▼ The use of data extracted from particle image velocimetry (PIV) along with vector and tensor
visualization techniques provides a valuable tool for understanding a complex
flow field. By studying a simple geometric structure such as a cylinder under a simple transient waveform, fundamental mechanisms of wake development under solitary wave
flow can be explored using this method of
flow visualization.
In order to quantify these wake formations, laboratory experiments were performed using a particle image velocimetery (PIV) system to extract velocity vector field data in the three planes of motion in the cylinder wake. Based on observations made from these images, the interaction of a cylinder with a solitary wave was categorized into three phases: 1) formation of a shear layer and generation of primary vortices, 2) generation of secondary vortices and shedding of primary vortices, and 3) migration of vortices outward and upstream of the cylinder.
A second
visualization technique developed by Zhang et al. (2008) and Palke et al. (unpublished) based on asymmetric tensor analysis is applied to the velocity data to determine non-translational components (volumetric dilation, angular deformation and rotation) of the cylinder wake. This technique provides a means of visualizing and quantifying the velocity gradient tensor components of scaling, stretching, and rotation in the fluid. These images provide valuable insight into the development and dissipation of vorticity in the cylinder wake. In particular, they suggest fluid elongation perpendicular to areas of intense rotation contributing to vortex dissipation outward and in the upstream direction of the cylinder.

▼ We consider the problem of efficient particle advection in a distributed- memory parallel setting, focusing on four popular parallelization algorithms. The performance of each of these algorithms varies based on the desired workload. Our research focuses on two important questions: (1) which parallelization techniques perform best for a given workload?, and (2) what are the unsolved problems in parallel particle advection? To answer these questions, we ran a “bake off” study between the algorithms with 216 tests, going to a concurrency up to 8192 cores and considering data sets as large as 34 billion cells with 300 million particles. We also performed a variety of optimizations to the algorithms, including fundamental enhancements to the “work requesting algorithm” and we introduce a new hybrid algorithm that we call “HyLiPoD.” Our findings inform tradeoffs between the algorithms and when domain scientists should switch between them to obtain better performance. Finally, we consider the future of parallel particle advection, i.e., how these algorithms will be run with in situ processing.
This dissertation includes previously published co-authored material.

▼ This study develops a general discrete
flow model which is
discrete both in time and space. A stirred tank network model
(continuous time compartment model) is summarized and then compared
with the discrete
flow model. Both models make use of a
fractional input matrix with elements representing the fraction of
flow
into the jth region which originates in the ith region. It is
shown that the discrete
flow model is more general and computatiomally
much simpler than the stirred tank network model.
The fractional input matrix is used to find the sizes of the
regions, to predict the residence time distribution (RTD) of the fluid
in
flow systems, and to compute the conversion for chemical reaction
occurring in a
flow system. Direct methods for finding the fractional
input matrix from either steady state or transient data are developed,
and methods and problems of fitting the model to data are presented.
Two simple numerical examples are given to demonstrate the use of
the model. Lumping is important for modeling
flow systems with very
many regions, thus a lumping analysis for discrete
flow systems is
presented. The methods for obtaining the sizes of the regions and the
fractional input matrix provide an important tool to analyze the lumping
problems in
flow systems.

▼ As the size and complexity of
flow data sets continuously increase, many vector field
visualization techniques aim to generate an abstract representation of the geometric characteristics of the
flow to simplify its interpretation. However, most of the geometric-based
visualization techniques lack the ability to reveal the physically important features. Additional efforts are needed to interpret the physical characteristics from the geometric representation of the
flow. In this work, the Lagrangian accumulation framework is introduced first, which accumulates various local physical and geometric properties of individual particles along the associated integral curves. This accumulation process results in a number of attribute fields that encode the information of certain global behaviors of particles, which can be used to achieve an abstract representation of the
flow data. This framework is utilized to aid the classification of integral curves, produce texture-based visualizations, study property transport structures, and identify discontinuous behaviors among neighboring integral curves. Although the accumulation framework is simple and effective, the detailed
flow behavior at individual integration points (and times) along the integral curves is suppressed, leading to incomplete analysis and
visualization of
flow data. In order to achieve a more detailed exploration, a new
flow-exploration framework is investigated based on the time-series data or Time Activity Curves (TAC) of local properties. In this framework, the physical behavior of the individual particles can be described via their respective TACs. An event detector based on TACs is proposed to capture the local and global similarity of any spatial point with its neighboring points with a new dissimilarity metric. A hierarchical clustering framework is then developed based on this metric, upon which a level-of-detail representation of the
flow can be obtained. This new framework is applied to a number of 2D and 3D unsteady-
flow data sets to demonstrate its effectiveness.

▼ Experiments were conducted in a recirculating water channel to determine the flow topology around a simplified two-wheel landing gear model. Both hydrogen bubble visualization and Particle Image Velocimetry techniques were employed. The Reynolds number based on wheel diameter was 32,500. The general flow topology was characterized for several wheel configurations. Previously undiscovered structures have been found in several regions of the flow field, and their behavior was found to depend strongly on the geometry of the wheels. The phenomena of vorticity amplification near the stagnation point of the wheels was also studied. Weak upstream vorticity was found to collect, grow, and amplify into large coherent structures which then shed in a regular manner. The size, location, and shedding frequency of these structures has been characterized. The impingement point of the upstream vorticity was found to dictate the dynamics of the phenomena.

Suspension Taylor-Couette flow: Investigation of particle loading effects on transitions between flow regimes.

▼ Taylor-Couette (TC)
flow refers to the
flow in the annulus between two coaxial, independently rotating cylinders. The TC system has been
subject to multiple experiments spanning over decades due to the instability phenomena that occur in the
flow. When the rotation rates of the cylinders are increased beyond a critical value, instabilities appear in the system that result in the formation of different
flow regimes. Single-phase
flow in the TC system has been studied extensively and the various
flow transitions have been catalogued for different geometrical parameters and rotational conditions. In the current experiments (Radius ratio= 0.917, Aspect ratio= 22),
flow visualisation with anisotropic reflective particles has been used to obtain qualitative and quantitative information about the different
flow regimes using Space-Time (S-T) plots and their spectral analyses. An aqueous glycerine solution was used as the working fluid for single-phase flows. The critical Reynolds number (calculated based on inner cylinder shear rate) for the transition from laminar Couette
flow was found to be slightly higher for the current setup in comparison to other experiments found in literature, but the order of
flow transitions and their spectral characterisation for all the
flow regimes showed good agreement, serving as a validation for the setup. With the established single-phase
flow as a base, the effect of particle loading on the
flow transitions was studied. A neutrally buoyant particle-laden suspension was prepared using an aqueous glycerine solution with Poly(methyl methacrylate) (PMMA) particles of 619-micrometer diameter. The volume fraction of the particles was varied from 0.05 till 0.40 and the
flow map was constructed for multi-phase
flow. The primary effect of particle addition is an earlier onset of the first transition from laminar Couette
flow, thus indicating a destabilisation of the
flow by particles. In addition to this, several non-axisymmetric
flow structures appeared in the suspension experiments which were absent in the single-phase
flow experiments. The particles caused the appearance of
flow regimes such as spirals (Taylor vortices that move up the cylinder axis in a helical motion) and ribbons (block-like structures that have alternating light and dark squares), which normally occur in the case of counter-rotating cylinders for single-phase
flow. The transitions across all volume fractions were characterised based on the S-T plots and/or spectra to obtain a consolidated
flow map for particle-laden suspensions. The results presented point towards intriguing
flow behaviour that provides a large parameter space for further research in the years to come.

▼ In recent times, the
visualization and data analysis
paradigm is adapting fast to keep up with the rapid growth in
computing power and data size. Modern scientific simulations run at
massive scale to produce huge datasets, which must be analyzed and
visualized by the domain experts to continue innovation. In the
presence of large-scale data, it is important to identify and
extract the informative regions at an early stage so that the
following analysis algorithms, which are usually memory and
compute-intensive, can focus only on those regions. Transforming
the raw data to a compact yet meaningful representation also helps
to maintain the interactivity of the query and
visualization of
analysis results. In this dissertation, we propose a novel and
general-purpose framework suitable for exploring large-scale data.
We propose to use importance-based data summaries, which can
substitute for the raw data to answer queries and drive visual
exploration. Since the definition of importance is dependent on the
nature of the data and the task at hand, we propose to use suitable
statistical and geometric measures or combination of various
measures to quantify importance and perform data reduction on
scalar and vector field data. Our research demonstrates two
instances of the proposed framework.The first instance applies to
large number of streamlines computed from vector fields. We make
the visual exploration of such data much easier compared to
navigating through a cluttered 3D
visualization of the raw data. In
this case, we introduce a fractal dimension based metric called box
counting ratio, which quantifies the geometric complexity of
streamlines (or parts of streamlines) by their space-filling
capacity. We utilize this metric to extract, organize and visualize
streamlines of varying density and complexity hidden in large
number of streamlines. The extracted complex regions from the
streamlines represent the data summaries in this case. We organize
and present them on an interactive 2D information space, which
allows user selection and
visualization of streamlines in the
original spatial domain. We also extend this framework to support
exploration using an ensemble of measures including the box
counting ratio. We strengthen our claims with elaborate case
studies using combustion and climate simulation datasets.We also
use our framework to speed up query-driven exploration of volume
data. Our approach speeds up range query response by using
distribution-based data summaries as opposed to repeatedly scanning
sub-domains of the raw data. Our work is mainly concerned with the
range distribution query, which returns the distribution of an
axis-aligned query region. Since the response time of such queries
scales up with the data and the query size, maintaining
interactivity is a challenging task. Our research offers the
ability to answer distribution query for any arbitrary region in
constant time, regardless of data and query size. We adapt an
integral image based data structure to reduce the computation, I/O
and communication…

▼ Statistical flow data such as commuting, migration, trade and money flows has gained manyinterests from policy makers, city planners, researchers and ordinary citizens as well. Therehave appeared numerous statistical data visualisations; however, there is a shortage of applicationsfor visualising flow data. Moreover, among these rare applications, some are standaloneand only for expert usages, some do not support interactive functionalities, and somecan only provide an overview of data. Therefore, in this thesis, I develop a web-enabled,highly interactive and analysis support statistical flow data visualisation application that addressesall those challenges.My application is implemented based on GAV Flash, a powerful interactive visualisationcomponent framework, thus it is inherently web-enabled with basic interactive features. Theapplication uses visual analytics approach that combines both data analysis and interactivevisualisation to solve cluttering issue, the problem of overlapping flows on the display. A varietyof analysis means are provided to analyse flow data efficiently including analysing bothflow directions simultaneously, visualising time-series flow data, finding most attracting regionsand figuring out the reason behind derived patterns. The application also supportssharing knowledge between colleagues by providing story-telling mechanism which allowsusers to create and share their findings as a visualisation story. Last but not least, the applicationenables users to embed the visualisation based on the story into an ordinary web-pageso that public stand a golden chance to derive an insight into officially statistical flow data.

▼ The helical coil steam generator is a type of tube and shell heat exchanger that is proposed for many small modular and Gen IV reactor designs. It is favored due to the higher heat transfer it provides compared to traditional U-tube steam generators, compact design and thermal stress flexibility. The arrangement of tubes, where the secondary two-phase fluid flows, determines the shell side, pressurized single phase
flow. This study focuses on the fluid structures that form in the shell side
flow when adjacent helical tube bundles coil in opposite directions. Two helical coil steam generator designs were created and studied using a high-resolution
flow visualization technique, refractive index matching particle image velocimetry (PIV). Experiments focused on multiple planes across each test section for different lateral pitch tube arrangements at Re ~ 8,500. Two-dimensional image sequences captured with a high speed camera were processed to determine average velocity
flow fields for x- and y-direction velocity components. Two main regions of
flow develop between tube bundle arrangements, center streamline
flow and recirculation regions below the tubes. Previous studies have shown these recirculation regions are responsible for the increase in heat transfer this geometry offers. Nevertheless, vortices that form in these regions have the potential to grow and enter the streamline, a phenomenon called vortex shedding. The frequency of this shedding behavior is currently correlated to lateral and transverse pitches between bundles. A comparative study showed that while the center streamline development remained consistent between helical coil steam generator models, the recirculation regions varied in strength and relative size. Areas with a larger lateral pitch, expected to have large recirculation development between the rods, did not have the highest velocity magnitude. These average velocity fields suggest that relative location along the coiling bundle also contributes to the vortex shedding behavior of the recirculation regions below the tubes. Future work aims to study the transient behavior of the
flow to have an in-depth analysis of the relationship between lateral pitch, transverse pitch, radial location around the helical coil tube bundle and recirculation region development.

▼ The Internet can be useful in supporting teacher planning and instruction. However, there is no way for teachers to know if they are progressing through the curriculum at an appropriate pace. The focus of this thesis is exploring the use of visualizations in aiding teacher planning and instruction. Visualizations were created using Processing, an open source programming language and environment. Data from the Curriculum Customization Service was used to display curricular
flow. The
visualization contains three layers representing the group's
flow, the ideal
flow, and an individual user's
flow. These layers show the
flow through the units of the curriculum. Another graph can be displayed by hovering over lines in the layered graph, which shows the most popular concepts among users. The visualizations were tested by asking five users to complete three tasks using the visualizations. All five users were able to complete the tasks though some had more difficulty than others, showing that while many improvements are needed, the visualizations do allow users to see their curricular
flow and make comparisons.

▼ With the increasing development of wind energy, it has become essential to study the interactions of turbines within wind farms. Wind turbines create wakes when harnessing the energy in the wind for electricity. Reduced velocities in the wakes and increased turbulence pose problems on nearby turbines. Therefore, to better understand the behaviour of wakes, experiments were conducted at the University of Waterloo Wind Generation Facility to study the behaviour of a wake behind a 3.3 m diameter turbine.
To ensure accuracy of measurements inside the facility, the flow distribution was measured upwind of the turbine to obtain a profile. This was completed through the development of a structure to orientate pitot tubes in front of the area of the turbine. The device allowed for various fan configuration settings of the facility to be tested to attempt
to obtain an even flow distribution profile. A completely uniform flow distribution could
not be achieved, however improvements to the profile were made.
Experiments were conducted through the use of ow visualization techniques to gain an initial understanding of the behaviour of the wake in both un-yawed and yawed turbine configurations. This was performed in two methods, to ignite a smoke emitter upstream of the turbine blade and to ignite smoke emitters on the blade tips of the turbine. Using the upstream smoke technique, the tip vortices could be seen to shed from the blades as they moved through the stream of the smoke. The vortices propagated downstream with the movement of the flow. The helical wake distribution of the wake could be seen using the blade ignited smoke technique. An estimate of the wake characteristics were obtained from this experiment, resulting in an approximate near wake length of 1.6 rotor diameters and helix angle of 30°.
Measurements of the wake of a wind turbine in un-yawed and yawed positions were conducted using three different measurement methods to gain an understanding of the wake behaviour in the range of 3 rotor diameters downstream of the turbine. The pitot tube structure previously developed was used to measure a two-dimensional profile of the wake at various downstream positions. With this method, the wake centre could be seen as well as temporal changes in the wake. A sonic anemometer was used to traverse the wake at hub height to obtain a horizontal velocity profile at various downstream distances. The velocity profile showed the decay of the wake as well as detection in the yawed turbine measurements. LiDAR measurements were collected by scanning the wake at hub height to obtain a flow distribution throughout the wake of the turbine. Through these measurements a clear wake profile was developed, which showed how the velocity profile progressed behind the turbine. When the turbine was yawed, the wake was seen to detect in the direction of the yaw angle.

▼ In this thesis, I will focus on developing computational methods that deliver intuitive and interpretable
visualization of single-cell data. The first chapter describes a software named Cluster-to-Gate (C2G) that can visualize existing clustering results of
flow/mass cytometry data in the format of 2D gating hierarchy. Though C2G presents a way to visualize and interpret clustering results, the
visualization is still data-driven and does not involve human-knowledge. To overcome the limitation of C2G, the second chapter describes a framework that can learn gating approach from existing publications to build a knowledge-graph. This knowledge-graph can automatically suggest the order of marker usage and gating hierarchy for the new data set, which can be used to gate the cell population. The obtained cell populations are immediately matched to some cell types in the knowledge graph, which makes them more interpretable. The third chapter describes a novel algorithm (GLaMST) to reconstruct lineage tree of B-cell receptor genes from high throughput sequencing data. This algorithm outperforms state-of-art in both accuracy and speed.

▼ Three-dimensional particle tracking velocimetry (3D-PTV) is a
flow measure- ment technique that tracks the Lagrangian paths of a set of particles using photogrammetric principles. This technique allows to investigate complex fluid flows by measuring velocity and acceleration along particle trajectories. Implementing and optimizing the technique is, however, a somewhat di - cult task involving accurate optical set-up, volumetric illumination, precise calibration and rigorous post-processing.
This thesis explains thorough guidelines to accomplish an optimal system set-up by discussing the hardware configuration, software operation, and post processing methods. First, this paper describes the system background for an e cient experimental set-up, such as the required camera specification, an accurate calibration method, an appropriate type of tracer particles and the illumination source. Then, the detailed usage of the 3D-PTV software, including the compilation and operation, with a description of file structures are discussed. To further utilize the output data, post-processing methods developed by Dr.Alex Liberzon, Dr.Beat Luthi and the author, which in- terpret the data both in Eulerian and Lagrangian frames, are explained. A circular jet
flow is analyzed as demonstration of the technique.

▼ Soccer is a fascinating sport that captures the attention of millions of people in the world. Professional soccer teams, as well as the broadcasting media, have a deep interest in the analysis of soccer matches. Statistical summaries are the most-used approach to describe a soccer match. However, they often fail to capture the evolution of the game and changes of strategies that happen. In this work, we present the Visual Soccer Match Analysis (VSMA) system, a tool for understanding the different aspects associated with the evolution of a soccer match. Our tool receives as input the coordinates of each player throughout the match and related events. We present a visual design that allows to quickly identify relevant patterns in the match. Our approach was developed in conjunction with colleagues from the physical education field with expertise in soccer analysis. We validated the system utility using several matches together with expert evaluations.

▼ Flow visualization plays an important role in many scientific and engineering disciplines such as climate modeling, turbulent combustion, and automobile design. The most common method for
flow visualization is to display integral
flow lines such as streamlines computed from particle tracing. Effective streamline
visualization should capture
flow patterns and display them with appropriate density, so that critical
flow information can be visually acquired. In this dissertation, we present several approaches that facilitate expressive
flow field
visualization and exploration. First, we design a unified information-theoretic framework to model streamline selection and viewpoint selection as symmetric problems. Two interrelated information channels are constructed between a pool of candidate streamlines and a set of sample viewpoints. Based on these information channels, we define streamline information and viewpoint information to select best streamlines and viewpoints, respectively. Second, we present a focus+context framework to magnify small features and reduce occlusion around them while compacting the context region in a full view. This framework parititions the volume into blocks and deforms them to guide streamline repositioning. The desired deformation is formulated into energy terms and achieved by minimizing the energy function. Third, measuring the similarity of integral curves is fundamental to many tasks such as feature detection, pattern querying, streamline clustering and hierarchical exploration. We introduce FlowString that extracts shape invariant features from streamlines to form an alphabet of characters, and encodes each streamline into a string. The similarity of two streamline segments then becomes a specially designed edit distance between two strings. Leveraging the suffix tree, FlowString provides a string-based method for exploratory streamline analysis and
visualization. A universal alphabet is learned from multiple data sets to capture basic
flow patterns that exist in a variety of
flow fields. This allows easy comparison and efficient query across data sets. Fourth, for exploration of vascular data sets, which contain a series of vector fields together with multiple scalar fields, we design a web-based approach for users to investigate the relationship among different properties guided by histograms. The vessel structure is mapped from the 3D volume space to a 2D graph, which allow more efficient interaction and effective
visualization on websites. A segmentation scheme is proposed to divide the vessel structure based on a user specified property to further explore the distribution of that property over space.

▼ The structures formed in the separated shear layer within a Laminar Separation Bubble (LSB) over a NACA 0018 airfoil at a chord Reynolds number of 100,000 and Angles of Attack (AOA) of (5°, 8°, and 10°) were investigated. Techniques used during investigation include high-speed flow visualization synchronized with embedded microphones for pressure measurements.
High-speed flow visualizations reveal the formation of coherent structures within the laminar separation bubble. These structures develop from disturbances that roll up into vortices, may merge, and then break down as the shear layer reattaches. Microphone measurements indicate that the growth of the structures are accompanied by growth in a band of frequencies in the fluctuating surface pressures. When simultaneous visualizations and microphone measurements were compared, it was found that a local pressure minimum indicates a vortex passing over a microphone. The merging of vortices was found to result in the merging of the associated pressure minima. To track vortices along the separation bubble, the microphone signals were cross-correlated around the minima. This tracking matches well with the reference tracking of vortices from images.
The vortex dynamics at AOA = 5°, 8°, and 10° were also compared. Visualizations show that structures decrease in scale at higher angles of attack, and show greater temporal variations. The spectra of pressure fluctuations show higher-frequency activity related to the smaller scales at greater angles of attack. The vortices at all of these angles of attack develop to a peak downstream of mean transition where roll-up is complete. At reattachment although the vortices come closer to the surface, the magnitudes of the pressure fluctuations decrease as the vortices break down. Merging of vortices was also investigated using the vortex tracking technique based on surface pressure fluctuations. Merging was present at AOA = 5°, 8°, and 10°, but more prevalent at larger angles of attack. Merging occurs at a range of intervals of vortices, and does not follow a dominant frequency from the disturbance environment.

▼ Exploratory
visualization and analysis of time-dependent vector fields or
flow fields generated by scientific simulations is increasingly challenging on modern supercomputers. One possible solution is the use of a Lagrangian-based in situ reduction and post hoc exploration approach. Although this approach offers improved accuracy-storage propositions, prior work has failed to evaluate the viability and efficacy of this method at scale. Additionally, there is a lack of understanding surrounding best practices that advance the effectiveness of
the Lagrangian-based approach. This dissertation contributes empirical studies measuring absolute error, calculating the practical in situ encumbrance, and understanding tradeoffs involving accuracy, storage, and performance. Further, this dissertation proposes algorithms that 1) improve accuracy-storage propositions via improved in situ seed placement and post hoc interpolation, and 2) achieve scalability via a communication-free model. Overall, the research presented in this dissertation establishes the viability and efficacy of using Lagrangian representations extracted in situ for post hoc exploratory
visualization of large time-dependent vector fields.

▼ Based on many studies and experiments, blood
flow patterns are associated with cardiovascular diseases and it usually is a sign of cardiovascular disease when the blood
flow becomes unusual. Magnetic resonance (MR) imaging is a non-invasive medical technique and the characteristic of phase contrast can use to measure the
flow velocity and patterns in vivo.
As far as we know, for the cardiovascular of region of interest, 4D
Flow-sensitive MRI technology is good at spatial coverage and temporal resolutions.It is easier for the researcher to analyze blood
flow patterns in the clinical diagnosis by
visualization processing.
EnSight (CEI, USA), a kind of commercial software, is often used to do
visualization processing of data of 4D
Flow-sensitive MRI. However, before
visualization of the data, several actions must be completed, such as ROI selection, correction or conversion of data, and etc.
Therefore, our thesis hopes to develop a simple but practical user interface tool for 4D
Flow-sensitive MRI data. From reading the file and ROI selection to correction and conversion of data as well as the
visualization processing are completed by this tool. It provides researchers a rapid examination of data and analysis of blood
flow patterns in the diagnosis.

▼ Boiling can provide several orders of magnitude higher performance than a traditional air cooled system in electronics cooling application. It can dissipate large quantities of heat while maintaining a low surface temperature to fluid difference.
Flow boiling with microchannels has shown a great potential with its high surface area to volume ratio and latent heat removal. However,
flow instabilities and early critical heat flux (CHF) have prevented its successful implementation. A novel
flow boiling design based on a mechanistic approach is taken to overcome the above mentioned disadvantages while presenting a very low pressure drop. The design uses open microchannels with tapered manifold (OMM) to provide stable and efficient operation.
The tapered manifold above the microchannels provides an increasing cross-sectional area in the
flow direction. The extra
flow cross-sectional area allows bubbles to emerge from the microchannels and expand in the manifold along the
flow direction. Using a 6% taper and a moderately high inlet liquid
flow Reynolds number of 1095, a CHF of 1.07 kW/cm
2 with a heat transfer coefficient of 295 kW/m
2°C and a pressure drop of 30 kPa was recorded. Baseline test with uniform manifold were conducted and compared with tapered geometry. The experimental data was substantiated with pressure drop modeling for the new geometry. High speed
visualization was also conducted to understand the underlying mechanism in the tapered configuration.

▼ Multiphase
flow is a common
flow when oil and gas are produced from underground, and in the process of hydrocarbon products transportation. Multiphase
flow meters have been one of the most important developments in oil and gas industries. The purpose of inventing a multiphase
flow meter is to measure the
flow rate of a fluid with multiple phases and/or the fraction of different components in the multiphase fluid.
Electrical impedance measurement is a method that has been recently applied so that a new type of multiphase
flow meter can be developed. Its principle is to record instantaneous measurements of impedance of a multiphase fluid. After comparing it to the impedance of each component of the fluid, the fractions of each component are known.
One of the limitations of this method is that the multiphase
flow needs to be well homogenized so that the measurement of impedance is accurate and steady. Therefore, in this study a slotted orifice plate is used to homogenize the multiphase
flow.
Venturi meters are commonly used to measure the
flow rate of a fluid. It uses a converging section of pipe to increase the velocity of the
flow which causes pressure drop according to Bernoulli’s theory.
Flow rate can be calculated when the differential pressure is measured.
Flow visualization is a method to get qualitative or quantitative information of a
flow by making the
flow patterns visible.
In this research,
flow rate and gas volume fraction of a water and gas
flow is measures by a slotted orifice plate
flow meter coupled with a Venturi meter in different orientations. Electrical impedance measurement method is used to obtain the Gas Volume Fraction of the working fluid. Results show that the gains of the signals at 1 MHz frequency have 6th order polynomial correlations with GVF values in both horizontal and vertical orientations, and that phase angles of the signals at 10 MHz frequency have linear correlations with GVF values only in horizontal orientation. The Venturi meter is used to measure the bulk
flow rates of the working fluid. The Discharge Coefficients of the Venturi meter is calculated to be 0.97 and 0.89 in horizontal and vertical orientations respectively. In addition, the Discharge Coefficient of the slotted orifice plate is proved to be independent from orientations. At last, a
flow visualization study is conducted to show different
flow patterns as well as the homogenization ability of the slotted orifice plate. Results of the
visualization study show that the slotted orifice plate has remarkable ability to homogenize the water-air mixture in all
flow regimes and in both horizontal and vertical orientations.

▼ The hydrodynamic and thermal boundary layers are known to be key regulators of the interfacial transport of mass, momentum and heat, which are crucial in a wide range of engineering and environmental applications. The boundary layers encountered in these applications are often turbulent in nature and characterized by the presence of three-dimensional motion and non-linear dissipative phenomena. The presence of heat transfer between the bulk fluid and the solid wall increases flow complexity due to the interaction of the buoyant force with flow inertia and non-linear coupling between thermo-fluid variables. As a key contributor to multiple engineering systems and environmental phenomena, advancement of the current knowledge on turbulent boundary layer dynamical behaviors is crucial.
In the present study, turbulent boundary layer flow over a heated horizontal smooth wall was investigated utilizing an experimental approach. The current state-of-the-art techniques for 3D flow characterization are often limited in their broad applicability. The present knowledge is improved upon with the development of a novel technique based on volumetric illumination with a multi-color pattern. In the absence of heat transfer, the turbulent boundary layer is known to contain a wide range of dynamical phenomena whose behaviors still lack a comprehensive understanding. The present study investigated the unheated turbulent boundary layer utilizing a unique implementation of the Particle Image Velocimetry (PIV) technique to characterize the three-dimensional (3D) nature of the flow and reported new findings on near-wall turbulent flow behavior. In the presence of heat transfer, once the buoyant force magnitude is sufficiently large, thermals detach and rise from the heated wall. The characteristics of thermals in a heated turbulent boundary layer was investigated in 3D utilizing PIV. A novel image processing algorithm was developed to detect thermals. The modification to the turbulent boundary layer velocity field by wall heating was studied utilizing PIV data. Results indicate that boundary layer behavior is influenced by the buoyant force via modification to the turbulent velocity field and associated velocity statistics. This study provides multiple new contributions on flow characterization techniques and the behaviors of the turbulent boundary layer in the presence and absence of heat transfer.

▼ The current study is a part of a long term experimental project devoted to investigate flow boiling heat transfer, pressure drop and flow visualization of R134a in small to mini/micro-diameter tubes. The experimental facility was first designed and constructed by X. Huo (2005) with the contribution of L. Chen (2006). In the present study, the experimental facility was upgraded by changing the heating system from AC to DC heating and also upgrading the logging system through using a faster data logger and developing a new Labview program. The objectives of the current study include (i) contribute in identifying the reasons behind the wide scatter in the published flow boiling heat transfer results, (ii) contribute in understanding the fundamentals of flow boiling heat transfer in mini/micro-diameter tubes and (iii) evaluation of the existing heat transfer and pressure drop prediction methods. Two sizes of stainless steel tubes were investigated in the current study; 0.52 mm and 1.1 mm diameter. In the current study, the 0.52 mm tube was roughly called a “micro-tube” whilst the 1.1 mm tubes were called “mini-tubes”. The present study proposes two possible reasons for the scatter in the published heat transfer results. The first reason is the variations in the heated length from one study to another–there is no criterion for choosing the heated length. The second reason is the variations in the inner surface characteristics of the channels from one study to another. These two important parameters were not taken into consideration by researchers in the past studies. Accordingly, the effect of the heated length was investigated in the current study using a seamless cold drawn tube with diameter of 1.1 mm and heated length ranging from 150 to 450 mm. The effect of the tube inner surface was also tested here by conducting the test in two stainless steel tubes with diameter of 1.1 mm and manufactured by two different processes. The first tube was manufactured by welding technique whilst the second tube was a seamless cold drawn tube. Both tubes were identical in design and dimensions. The inner surface of each tube was examined first using SEM analysis and demonstrated that, the surface morphology is completely different. The local heat transfer coefficient was determined through measuring the local wall temperature using 14 K-type thermocouples attached to the wall using thermally conducting but electrically insulating epoxy supplied by Omega. Pressure drop was measured directly across the heated section and a high speed camera was used for the flow visualization at 1000 frames/s. All measurements were recorded after the system attained steady state. The experimental conditions include mass flux range of 100 – 500 kg/m2 s, system pressure range of 6 – 10 bar, inlet sub-cooling of about 5K and exit quality up to about 0.9. The most frequently observed flow regimes in the 0.52 mm tube were found to be slug (elongated bubble), transition to annular and annular flow regimes. In the 1.1 mm tube, the observed regimes were found…

▼ Often times, simulations involve repeated runs where certain parameters, e.g. initial and boundary conditions, or model parameters are varied slightly, in order to capture the variability of the phenomenon being studied. The results are referred to as ensembles. Ensembles are very attractive since they represent both the data values and their uncertainty. Ensembles challenge us to extend traditional visualization assuming that the ensemble represents the distribution of all possible simulation outcomes given an input parameter space. Extending the traditional paradigm is also better suited for complex data associated with ensemble vector fields (EVFs). Derived features of the EVF allow for their summary visual analysis. This approach is related to traditional methods of visualization for crisp fields but require the definition and calculation of additional derived features of interest.We first focus on a consolidated and extensible representation of EVF. A distinguishing aspect of this dissertation is the treatment of the values at each spatial point of the ensemble field as forming a probability distribution function (PDF) that need not conform to a Gaussian distribution. We present a new method for interpolation of distributions of 2D vector fields, required for handling velocity distributions. We also include velocity probability density information from the EVF in the feature set of streamlines.Another defining characteristic of this work is considering streamline information content and geometrically based streamline clusters as a derived feature of EVF. We apply a suitable and proven streamline clustering method first introduced to summarize regions of crisp vector fields. Our contribution is redefining this method for use in EVF, both for seed points over the spatial domain and for entire sub-regions of the EVF. We also show correlation between the associated cluster counts and streamline information content at seed points in the EVF.Our goal is to enable simulation scientists and consumers of ensemble data sets, such as weather forecasters, to visualize areas of predicted flow that are improperly represented by a Gaussian simplification. The potential impact of this work ranges from better representation of current weather prediction forecasts for public consumption to the refinement of computational fluid dynamics (CFD) models.

▼ Multiphase flows are encountered in the majority of crude oil wells. Electrical Submersible Pumps (ESPs) are used to pump the crude oil in wells that do not have sufficient pressure head. Conventional ESPs are mixed or radial
flow pumps which have limited gas handling capabilities. For handling high GVF (Gas Volume Fraction) fluids, advanced gas handlers (a type of ESP) were used in series before the conventional ESPs. These homogenize the
flow and eliminate gas lock occurrence. The behavior of ESPs (Advanced Gas Handlers) under two phase flows was not widely understood. To better understand the behavior, a helico-axial pump capable of handling fluids up to 90% GVF has been investigated.
Using the high pressure closed loop test facility at the Turbo Machinery Laboratory, a 4-stage helico-axial pump has been tested experimentally using water and air as test fluids for varying conditions such as inlet pressure,
flow rate, GVF, and rotating speed. Performance maps of the pump along with vibrational characteristics have been obtained to identify the Best Efficiency Point (BEP) and stable operating regimes. The head degradation of the pump under two phase
flow conditions as a function of stage has been obtained. From the head degradation results, the number of advanced gas handler stages to be used before conventional ESPs in an actual assembly has been identified to improve the total system efficiency when used in the field. Based on the experimental data, a new empirical model is developed to predict the stage by stage performance under multi-phase
flow conditions.
To understand the two-phase
flow behavior in the pump,
flow visualization was performed on a full scale single stage pump that was designed and built using transparent Polycarbonate material.
Flow visualization was performed using a laser and a high speed camera. The
visualization has provided much insight into how the
flow goes through the pump: showing recirculation zones, back
flow, vortices, and impeller diffuser blade interaction. The bubble diameter obtained from the
flow visualization is being used as one of the inputs to allow two phase CFD Simulations.
The efficiency of Advanced Gas Handlers is less than conventional ESPs. To better understand the
flow behavior, 3-D single- and two-phase
flow through the pump was modeled numerically using the commercial software ANSYS. The pump
flow model was validated using the experimental data. From the single-phase simulations, regions of improvement were identified to increase the efficiency of the pump. Different diffuser designs were evaluated to improve the performance of the pump. Two-phase simulations are performed to study the homogeneity of the
flow and to identify head degradation. Head degradation can be improved by identifying the regions where the phases tend to separate in the
flow path and eliminating them.

▼ A series of experimental work to investigate the subcooled boiling
flow in a vertical square upward
flow channel is described. As experimental methods, high-speed photography and infrared (IR) thermometry were employed simultaneously. The research scope explored includes (i) measurement issues of fundamental bubble parameters through
visualization, (ii) experimental methodology to achieve both enhanced two-phase
flow visualization and accurate wall temperature measurement, and (iii) measurement of diverse aspects of bubble dynamics as well as wall heat transfer by applying the verified experimental approach.
Before producing the actual data, substantial effort was first made to identify the critical measurement issues of fundamental bubble parameters in a forced convective boiling system. Those issues have never been explicitly addressed in previous studies despite the possibly critical impacts on the experimental results. Thus, a series of systematic experimental investigations was performed to uncover those issues and to verify the errors created by not addressing them, based on which more suitable ways of observing and characterizing such parameters through experiments were discussed.
Then, an experimental strategy to achieve high-fidelity optical measurements using both high-speed photography and IR thermometry was established. To attain the goal, the important issues such as test section design, IR thermal imaging issues,
visualization strategy, wall temperature tracking method, and experimental validations were extensively addressed. Also, the feasibility of current experimental approach was demonstrated through the subcooled
flow boiling experiment.
Finally, by employing the experimental strategy established, an experimental investigation of the subcooled boiling
flow was conducted. The experiment was performed in a vertical square upward
flow channel using refrigerant NovecTM 7000, in which a single nucleation site was purposely activated for a fundamental study of subcooled
flow boiling process. The various aspects of bubble behavior under different subcooled
flow boiling conditions were examined using both micro- and macroscopic views of high-speed cameras while measuring the wall temperature/heat flux with IR thermometry. Additionally, based on the measurements of various bubble parameters as well as wall heat transfer, relevant relations among those parameters and the underlying mechanisms were intensively discussed.

▼ Contingency analysis is a critical technique for evaluating the operational capability of power systems and characterizing their vulnerability to component faults. The traditional requirement for reliable operations has been an n-1 security constraint – an electrical network should be resilient to contingencies involving any one element.Contingency analysis is critical to evaluating the operational capacity of power systems and characterizing their vulnerability to component faults. As we look to increase the resilience of networks to element failure, the instance of multiple contingencies is of growing concern for planners and operators in identifying weak points in the system. Multi-element contingencies introduce new challenges for how to reliably and consistently measure the severity of a fault, how to perform contingency analysis on an expanding range of contingency scenarios in a timely manner, and how to interpret the increasingly hierarchical data obtained by contingency analysis. This research explores techniques that can be used to generate, summarize and display the results of multi-element contingency analyses in power systems, including high-performance computational methods for evaluating contingencies and new visualization techniques that leverage visual summarization and live interaction to extract valuable insights from the resulting data.
