▼ This thesis deals with two problems in viscous flow.In the first part, fluid-structure interactions were investigated, with connections to swimming microorganisms. Motivated by a numerically proposed swimming mechanism, we studied an elastic straight rod rotating on an imaginary cone. The shapes of the rod which rotates at either prescribed torques or speeds were experimentally measured and theoretically calculated. The rod undergoes a discontinuous transition to a helical shape at a critical torque, with increased propulsion force. A simple model was presented to capture and explain the essential physics. In addition, the longstanding hypothesis of hydrodynamic synchronization was investigated using a scale model experiment. We demonstrated that hydrodynamic interactions can cause synchronization between rotating paddles driven at constant torque if the shafts supporting the paddles have some flexibility. The synchronization state depends on the symmetry of the paddles and the torque mismatch. Excellent agreements were shown between the experiments and the regularized stokeslets simulations. And a simple analytic theory was built to predict the synchronization time as a function of paddle separation.In the second part, contact drop formation on a hydrophobic surface was examined experimentally and theoretically. A wide range of droplet sizes can result from the same syringe by varying the dispensing speed. Three dispensing regimes were identified according to the motion of the contact line, a line coexisting between liquid/vapor/solid interfaces. In the fixed and the expanding contact-line regimes, a power dependence of the drop sizes on the dispensing speeds was observed experimentally and obtained theoretically. In the receding contact-line regime, the contact-line motion consists of two stages: a slow retraction at the beginning and a rapid retraction immediately prior to drop breakup. The dispensing process was modeled as a stretching liquid bridge with a free moving contact-line. A quasi-static analysis and numerical calculations were performed to accurately predict the initial evolution of the liquid bridge and the final breakup respectively. The influences of the contact-line movement on the onset instabilities of liquid bridges and thus the deposited drop sizes were discussed.

Ph.D. University of Hawaii at Manoa 2012.

This thesis conducts the investigation into the metallicity history of galaxies between redshift 1 and 3, using gravitationally lensed galaxies. We use metallicity as a tool to understand the formation and evolution history of galaxies. We direct our research in two areas. 1. We combine our new sample of gravitationally lensed galaxies with existing lensed and nonlensed samples to conduct the largest investigation so far into the mass-metallicity (MZ) relation at z > 1. We apply a self-consistent metallicity calibration scheme to investigate the metallicity evolution of star-forming galaxies as a function of redshift. We find that at the median redshift of z = 2.07, the median metallicity of the lensed sample is 0.35 dex lower than the local SDSS starforming galaxies and 0.18 dex lower than the z ∼ 0.8 DEEP2 galaxies. Our lensed sample shows a much larger metallicity range and scatter (> 0.2 dex) than the z ∼ 2 UV selected galaxies at similar masses. These offsets translate into a metallicity evolution of-0.23±0.01 dex per unit redshift from z ∼ 0 → 1, and-0.14 ± 0.08 dex per unit redshift from z ∼ 1 → 3. A more rapid evolution is seen between z ∼ 1 → 3 (with a mean fall in metallicity of-0.05 ± 0.01 dex Gyr−1) than z ∼ 0 → 1 (-0.020 ±0.001 dex Gyr−1). This evolution agrees with the most recent cosmological hydrodynamic simulations with momentum driven winds within the errors. 2. Combining the magnification power of gravitational lensing and AO-aided Integral Field Unit spectrographs (IFUs) is the only way to achieve sufficient signal-to-noise and angular resolution for spatially resolved metallicity studies. Using this technique, we present the first metallicity gradient measurement for a grand-design face-on spiral galaxy at z ∼ 1.5. The gradients of our spiral and another 2 lensed galaxies at z ∼ 2 are much steeper than local disk galaxies, supporting an "inside-out" galaxy formation scenario. We also report spatially resolved emission lines of a z ∼ 1 lensed galaxy. We find significant shock excitation due to galactic outflows. Our analysis suggests that shocked regions may mimic flat or inverted metallicity gradients at high redshift. We find that high angular resolution observations provide the most accurate metallicity gradient measurement,whereas seeing-limited studies under estimate the slope of the gradients

▼ Using two hydrodynamic galaxy formation simulations from the Mufasa project that I helped develop, we aim to better understand the relationship between galaxy evolution and its cold gas content commonly known as the neutral hydrogen or Hi. We first look at the environmental properties of the simulated galaxies and compare to those that are available observationally. As a proxy, we specifically quantify the so-called galactic conf ormity, which is the concordance between the properties of galaxies neighbouring the primaries, in chapter 2. We show that the Hi, the specific star formation rate (sSFR) and the colour of galaxies show galactic conformity in qualitative agreement with previous observed data, i.e. the Hi-rich primary galaxies are surrounded by Hi-richer galaxies than the Hi-poor primary galaxies, and similarly for the sSFR and the colour. We find that environment, quantified by the number of neigbouring galaxies within a fixed aperture, stellar age and molecular hydrogen (H2) also show conformity. Galactic conformity also depends on the dark matter halo mass of the primary galaxy. The galactic conformity signal from the primaries of smaller haloes is weak but extends out to several virial radii of those structures, whereas the signal is very strong for high mass haloes but lowers quickly with distances from the primaries. We also find the galactic conformity only emerges in the later half of cosmic evolution. We next quantify the gas content and star formation depletion timescales in chapter 3. We use two carefully chosen groups of simulated galaxies and find that timescales are affected by both the mass of the virialised structure of the first infall and the galaxy stellar mass at infall: the higher the halo mass or the stellar mass the shorter the timescale. The gas or Hi depletion timescale is concordant to that of the star formation quenching, indicative of direct decrease of SFR due to depletion of the extended cold gas reservoir. The neutral atomic or molecular hydrogen consumption timescale depends on the Hubble time. Galaxies tend to form stars more efficiently at lower redshift. While the halo mass of infall affects the consumption timescale of the Hi, it does not correlate with the H2. We lastly develop machine learning tools to use galaxy photometric data to predict a galaxy’s Hi mass in chapter 4, to allow predictions for Hi from much larger optical photometric surveys. The training and testing of the algorithms are done first with the simulated data from Mufasa. We show that our model performs better than previously done with ad hoc data fitting approaches. Random Forest (RF) followed by the Deep Neural Networks (DNN) perform best among the explored machine learning techniques. Extending the trained models to observed data, namely the Arecibo Legacy Fast ALFA (ALFALFA) and REsolved Spectroscopy Of a Local VolumE (RESOLVE) survey data, we show the overall performance is slightly reduced relative to the simulated testing set owing to the small inconsistency between… Advisors/Committee Members: Dave, Romeel (advisor).

▼ Ohiwa Harbour is an estuarine lagoon located in the eastern Bay of Plenty, North Island, New Zealand. Ohiwa Harbour is bounded by two sand spits, Ohope and Ohiwa Spits. This study assessed the likelihood of a resistant barrier underlying Ohiwa Spit, which would control the inlet and spit locations. The observed depths of layers unable to be penetrated by a vibrocorer on Ohiwa Spit supported this idea, along with the discovery of a rock outcrop on the eastern harbour entrance using sidescan SONAR. Vibrocoring on Ohiwa Spit added to the knowledge of the prehistoric evolution of Ohiwa Harbour, and an attempt to infer various subsidence events on Ohiwa Spit were made. Fining upwards coarse sand sequences with dominant shell material were found in the cores. These sequences could be related to a change in harbour hydrodynamics, or recent subsidence events in Ohiwa Harbour, such as the 0.6m subsidence of the Waimana Fault 636 to 575cal yrs BP. A sharp change in the core profile was observed at 1.4m in core C and 1.7m in core C2, marked by increased grain size and an abundance of shell material, mostly Austrovenus stutchburyi. This could be related to a change in wave energy in the harbour or an erosional contact associated with subsidence of Ohiwa Spit. Comparison of radiocarbon dated shells in this study with Murdoch (2005) on Ohope Spit suggests that more subsidence has occurred at Ohiwa Spit than Ohope Spit; this may be associated with a fault through the harbour entrance. Subsidence associated with earthquakes, and erosion associated with at least four tsunami events in the last 6000 years has increased the depth and extent of Ohiwa Harbour, increasing its volume. This study used numerical modeling to determine the hydrodynamic impacts of past catastrophic events (earthquake related subsidence and volcanic eruptions) on Ohiwa Harbour. Ten scenarios along with present conditions were modelled. • In scenarios where sea level was modified only (scenarios 1-5 and 8), tidal range and surface elevation increased within the harbour, but not at the harbour entrance. The entrance hydrodynamics were also influenced by its width; as Ohope Spit accreted, the surface elevation and flow velocities increased within the tidal inlet • Flow speeds increased at the harbour entrance by up to 50% following subsidence in scenarios 9 and 10 • A drop in sea level during subsidence (scenario 6) resulted in a smaller tidal prism and hence reduced flow velocities at the inlet, despite the subsidence • Scenario 7 involved subsidence and the breaching of Ohope Spit, which would divert flow away from the entrance and result in reduced flow velocities at the entrance Advisors/Committee Members: de Lange, Willem P (advisor).

▼ An efficient and robust predictive technique has been developed for the analysis of dynamically loaded, flexible journal bearings using the finite element method. The work is in two parts. In the first part a fast predictive technique is developed for the analysis of dynamically loaded, rigid journal bearings. The finite element formulation of Reynolds equation is presented using both 3-node triangular and 8-node isoparamteric elements to model the lubricant film. The latter are shown to approximate the problem more closely using fewer nodal points and hence requiring fewer equations. The Gauss-Seidel over-relaxation method is used to solve the resulting system equations and the sparseness of these equations is exploited. Comprehensive results are presented for the Ruston and Hornsby 6VEB Mk ifi marine diesel engine connecting rod bearing. Two different time stepping methods are considered and the effects of incorporating various oil feed features in the analysis are also presented. The second part of the work deals with the flexible bearing problem. The method of carrying out the structural modelling and the way in which the structural compliance relationships are obtained is described. A fast matrix inversion technique used to obtain these relationships is also described. Based on the rigid bearing work 8-node isoparametric elements are used to model the lubricant film. Two methods are presented for coupling the structural and lubrication analysis. The first method, the under-relaxation method, although proving straightforward to implement is shown to be unsatisfactory for this particular problem due to to convegnence problems. The second method is the Newton-Raphson method which is shown to be highly convergent. The Newton-Raphson method is subsequently highly modified to produce a fast solution method. This is shown to be several orders of magnitude faster than any previously developed method making this technique viable as a general design tool rather than just providing benchmarks against which to compare simpler analysis techniques. Again results are presented for the Ruston bearing showing the effect upon the predicted performance of incorporating elasticity into the analysis.

Hydrodynamic separators are widely used in urban areas for removal of suspended sediments and floatables from stormwater due to limited land availability for the installation of above ground stormwater best management practices (BMPs). Hydrodynamic separators are often sized based on relatively frequent storm events. However, during less frequent storm events, device design treatment rates are exceeded and previously captured sediments can be washed out of the devices. To study the potential for scour and washout of previously deposited sediments in the sumps of hydrodynamic separators under high flow conditions during infrequent storm events, sediment washout testing methods using mass balance were developed for both controlled field testing and laboratory testing. The developed testing methods were utilized to conduct sediment washout testing on three full scale hydrodynamic separators: 1) an Environment21 V2B1 Model 4, 2) a STC1200 Stormceptor and 3) a 6-ft Downstream Defender. All three devices were tested in the laboratory. The Environment21 V2B1 device was also tested in the field. In addition to full scale testing, two scale models were constructed and tested in the laboratory. Previous work by others on describing sediment washout in standard stormwater sumps was applied to data obtained from the sediment washout tests to develop sediment washout functions which incorporate non-dimensional parameters. Washout functions were developed for each of the devices tested in the laboratory and the field, as well as for a modified ecoStorm device previously tested by others. The washout functions that were developed can be incorporated, along with removal efficiency functions, into continuous urban runoff models to predict maintenance schedules for hydrodynamic separator devices.

▼ Integrally geared compressors (IGCs) comprise of single stage impellers installed on the ends of pinion shafts, all driven by a main bull gear (BG) and shaft system. When compared to single shaft multistage centrifugal compressors, the benefits of IGCs include better thermal efficiency, reduced footprint and simple foundation, dispensing with a high speed coupling, as well as better access for maintenance and overhauls. In IGCs the compression of the process gas induces axial loads on the pinion shafts that are transmitted via thrust collars (TCs) to the main drive shaft and balanced by a single thrust bearing. The TCs, located on either side of pinion gears, slightly overlap with the BG outer diameter to form lentil-shaped lubricant-wetted regions. A numerical model, based on classical thin film lubrication theory, predicts the force response of lubricated thrust collars for use in integrally geared compressors. The predictive model determines performance parameters such as lubricant flow rate, mechanical power loss, peak pressure, lubricant temperature rise, as well as rotordynamic stiffness and damping coefficients for a lubricated TC and bull gear pair. A Newton-Raphson based iterative procedure determines an equilibrium operating position for a given set of TC and BG operating conditions and geometry. Periodic, dynamic displacements from the equilibrium position renders complex dynamic stiffnesses (H = K+i?C), from which the fluid film force and moment stiffness and damping coefficients are determined. In a lubricated thrust collar and bull gear, a hydrodynamic pressure builds in the lower half of the lubricated zone and lubricant cavitation occurs in the upper half. The minimum film thickness and peak pressure in the lubricated zone shift location due to the difference in taper angles between the TC and BG surfaces. For a given applied load, a study on the differences in taper angle between the TC and BG surfaces reveals that current angular tolerances of ?0.1 produce TC/BG pairs with similar performance parameters (power loss, lubricant temperature rise, etc.) and dynamic force and moment stiffness and damping coefficients. Increasing the taper angles of both the TC and BG decreases mechanical power loss and lubricant temperature rise, but also decreases the fluid film axial stiffness and damping coefficients. In addition, static angular misalignments of the TC and BG about the horizontal (x) axis joining the BG and TC centers alters the shape and extent of the lubricant cavitation region. This change alters the load carrying capacity and mechanical power losses of the lubricated element. For the specific TC/BG pair investigated herein, there exists a maximum difference between the two taper angles for which the mechanical element can support an imposed thrust load. Increasing the speed of the BG (and proportionally the TC speed) increases the mechanical power loss and lubricant temperature rise and decreases the fluid film axial stiffness and damping coefficients. As with most fluid film bearings,… Advisors/Committee Members: San Andres, Luis (advisor), Childs, Dara (committee member), Strouboulis, Theofanis (committee member).

▼ In the northwestern Gulf of Mexico there is a need for reliable water level forecasts to facilitate safe commercial navigation, marine construction, and emergency management. Though the low amplitude tides of the region can be predicted with conventional harmonic techniques, frequent strong storms make accurate forecasts of water levels difficult. Prediction of surge associated with storms is useful for management of activities in low lying coastal areas subject to flooding, while prediction of drawdown is important for estimating the under keel clearance of deep draft vessels. First, this thesis presents the analysis of nine years of observations to quantify the effects of extra-tropical storms on water level fluctuations at four locations along the northwestern coast of the Gulf of Mexico. The monthly root-mean-square of the meteorological component of the observed water level is shown to be of similar magnitude to the astronomical tide from September to April, attributed to the weekly passage of storm systems. Return periods for extreme maximum (surge) and minimum (drawdown) meteorological water levels associated with these storms are computed using a 9-year record of observed water levels. Significant surge and drawdown water levels, defined as those exceeding 30 cm, are shown to have return periods ranging from 0.17 to 7.14 years at the four stations studied. At the entrance to Galveston Bay, Texas, both significant storm surge and drawdown can be expected to occur about four times each year. These results reinforced the need to include meteorological forcing in the forecasting of water levels in the region. In an effort to provide more accurate water level forecasting within Galveston Bay during storms, the finite element (FE) hydrodynamic model ADCIRC was applied to simulate a range of observed storm events by inclusion of wind stress and remote forcing from the Gulf of Mexico. Comparisons with observations showed the limited accuracy of ADCIRC, as applied here, in predicting the water level response for drawdown events. Thus, the ADCIRC output was incorporated into a data assimilation method utilizing artificial neural networks (ANN). This hybrid FE/ANN approach substantially improved the pure FE simulations for short term forecasts and also outperformed other forecasting methods. With further refinement, this hybrid approach could provide operational forecasts of water levels within Galveston Bay during storms. Advisors/Committee Members: Cox, Daniel T. (advisor), Haller, Merrick (committee member).

▼ The work detailed in this thesis investigates the behaviour of the hydrodynamic interaction effects acting on an unappended AUV manoeuvring in proximity to a larger moving underwater vehicle such as a submarine. The investigation examined the steady-state and transient interaction effects on the hydrodynamic coefficients of the AUV as a function of the relative: speed, longitudinal position, lateral position, and size between the two submerged vehicles. The work involved extensive development of Computational Fluid Dynamics (CFD) models to simulate the manoeuvres in order to map the interaction behaviour. Experimental Fluid Dynamics (EFD) involving captive-model tests of the two vehicles were carried out to validate and supplement the CFD data. The results show that the hydrodynamic interaction acts to attract and repel the AUV at the stern and bow regions around the submarine, respectively. The magnitude of these attraction and repulsion interaction effects varied significantly due to small changes in the relative longitudinal position, suggesting the need of an accurate and fast responsive control system for the AUV to adequately maintain its trajectory around the submarine. These adverse interaction effects were found to be minimal around amidships of the moving submarine, suggesting a safe path for the AUV to approach or depart the submarine laterally within that region. In addition, the interaction effects on the hydrodynamic coefficients of the AUV were shown to reduce as the relative speed of the latter increased. Due to the need to simulate large relative motions between the two vehicles, this thesis also investigate and identifies the merits of two dynamic mesh techniques within ANSYS CFX (i.e. Immersed Solids, and AMP Re-Meshing) to simulate multiple bodies in relative motion. Although the numerical models behind the techniques have undergone substantial development in recent years, as they are beta-features in ANSYS CFX there are currently no existing studies demonstrating their capabilities in modelling multiple bodies in relative motion. The developed CFD simulation models are suitable for future work involving appended AUVs and the coupling with a control system for manoeuvring simulations of multiple underwater vehicles.

▼ The function of a sensory system is to effectively extract relevant information about the environment in order for an organism to make behavioral decisions. Sensory stimuli can be shaped, in part, by their propagation within the local habitat. In order to separate relevant information from background noise, sensory systems are equipped with filters. Because information differs between environments, sensory filters are matched to the specific environment in which an organism lives, thus developing what are known as 'matched filters.' An organism's sensory filters are therefore 'tuned' to the demands of its unique sensory environment. The 'tuning' of an organism's sensory system is caused by the pre-existing sensory biases that are inherent within an organism. As interactions between an organism and its environment are continued over time, natural selection will drive an organism's sensory biases to align, or become 'tuned,' to use types of information that are relevant within the specific environment. The purpose of this thesis is to determine how the sensory biases of aquatic organisms will influence their behavior in response to chemical information. In order to ascertain this knowledge, the orientation behavior of crayfish, Orconectes virilis originating from two distinct hydrodynamic habitats (i.e. lentic and lotic) was tested. Crayfish originating from each habitat were allowed to orient to an odor source under both lentic and lotic conditions. We analyzed both spatial (e.g. heading angle) and temporal (e.g. walking speed) characteristics of the orientation patterns. The results of this study showed that each type of crayfish displayed unique orientation behaviors under each condition. From these results we conclude that lentic and lotic crayfish, O. virilis have behaviors that are uniquely 'tuned' to the hydrodynamics of their native habitat. Furthermore, this supports the theory that 'sensory biases' drive an organism to develop 'matched filters.' Advisors/Committee Members: Moore, Paul (Committee Chair).

▼ Bearings are basic and essential components of nearly all machinery. They must be designed to work under different loads, speeds, and environments. Of all the performance parameters, load-carrying capacity (LCC) is often the most crucial design constraint. The objective of this research is to investigate different design methodologies that significantly improve the LCC of liquid-lubricated bearings. This goal can be achieved by either altering the surface texture or the bearing geometrical configuration. The methodology used here is based on mathematical topological/shape optimization algorithms. These methods can effectively improve the design performance while avoiding time-consuming trial-and-error design techniques. The first category of design studied is a micro-scale mechanical self-adaptive type which can provide “flexible surface texturing”. An accurate 3D model based on the classic plate theory and thin film lubrication is developed and a shape optimization analysis is carried out. Special attention is given to the cavitation phenomena and its numerical analysis. Also proposed is a numerical procedure to improve the convergence rate and stability of the Elrod cavitation algorithm. The idea of using self-adaptive mechanism to improve LCC is also adopted for thrust bearings. Novel flexible-pad thrust bearing designs that provide an optimum load-responsive mechanism are presented and an accurate multi-physics model that considers the coupled mechanism between the lubricant pressure and the pad deformation is developed. The optimum shapes for different bearing geometries are given and a detailed design guideline is provided for optimum performance. The second category of design studied focuses on bearing geometrical configuration. The optimum shape of finite width sectorial sliders, which is an open problem in the field, is determined for the first time in this research using topological optimization algorithms. Also three suboptimum solutions for special cases of 2D step profile, constant film thickness in the radial direction and constant film depth with quadrilateral shape are presented. These configurations are particularly attractive because they can be easily manufactured. The optimum shape of bearings with periodic surface grooves is also determined in this research. It is shown that the optimum shape is dependent to the aspect ratio of the grooves and it can change from elongated “heart-like” shapes to spiral-like shapes. A series of laboratory tests to authenticate the theoretical development is carried out. Results show very good agreement with the theory validating the accuracy of the model. Finally, the optimum geometry of spiral grooves that provide the highest LCC in liquid-lubricated parallel flat surface bearings is determined and a detailed design guideline is provided. The thermal effects are also considered and an approximate thermo-hydrodynamic model is developed for a range of seal geometries and operating conditions.

▼ In the last two decades many microfluidic devices have been developed in order to provide better and more reliable tools for biological assays and analysis. Microfluidic technology has proven its functionality and advantages over conventional cellomics methods such as flow cytometry (FC) and laser scanning cytometry (LSC) in particular for processes that require the analysis of single cells. Different microfluidic platforms capable of capturing, positioning, and sorting single cells have been developed; however, such devices are incapable of working with various sizes of cells. Therefore, once a device has been designed and fabricated it is not possible to modify its dimensions so a new device is required for each different cell size for analysis. In an effort to overcome the limitation of adaptability of microfluidic cell trapping devices, this thesis presents a new microfluidic single cell-trapping device capable of capturing cells of various diameters. This thesis conducts a review and analysis of several microfluidic cell trapping devices under the FCBPSS (function-context-behavior-principle-state-structure) framework to have a better understanding and classification of the most relevant microfluidic devices, followed by the design of a new device capable of trapping large batches of single cells and modifying its physical features in order to work with multiple sizes of cells. The design process of the new device is based on and guided by the Axiomatic Design Theory. From the thorough review of the literature, it was concluded that the most suitable structure to demonstrate the concept proposed on this thesis an array of single cell trappers, and the best tuning method would be a mechanical stretching to generate a uniform distributed strain on the device. After designing and modeling the new device, it was imperative for this research to fabricate a device which could be tested in accordance with the literature. The final device consists of two thin layers of polydimethylsiloxane (PDMS), one of which bears trapezoidal microstructures (traps) to physically capture cells. The size of the traps can be modified by stretching the device via a uniform distributed force, which is applied using a stretching apparatus. Finally, the performance of the new device was assessed by conducting two main experiments. The first experiment consisted of characterizing the mechanical behavior of the device when different strains were applied. It has been found that all the traps of the device have a uniform deformation when a strain is applied, and the minimum size increment permitted by the stretching apparatus is of 2μm.The second experiment was done in order to characterize the hydrodynamical and trapping behavior of the device. By using water-in-oil microspheres of various sizes the trapping of particles was demonstrated; it was determined that the device can capture particles between 20μm and 30μm. To demonstrate cell viability, the device was tested using melanoma cells. No visible damage onto the cells was observed after… Advisors/Committee Members: Zhang, Chris, Badea, Ildiko, Yang, Qiaoqin, Szpunar, Jerzy A, Deters, Ralph.

▼ A high-resolution, three-dimensional, hydrodynamic model of the Duplin River estuary on Sapelo Island Georgia has been developed using Finite Volume Community Ocean Model. Using a model to describe transport and retention is a good way to estimate the efficiency of an estuary at remediating contaminants. The model shows good agreement with time series of sea surface height and salinity from monitoring stations within the domain. The model does well at predicting tidal oscillations and subtidal SSH and salinity variations. However, there is room for improvement with regard to salinity variability in the upper model domain. A Lagrangian particle tracking analysis was carried out to study the effects of semi-diurnal tides, spring/neap tidal cycles, and seasonal forcings on residence times. Residence time is most sensitive to the stage of the tide (slack high or slack low) when starting the particle tracking and had maximum values on slack low water. Neap tides had characteristically longer residence times than spring tides. Residence time was also dependent on seasonal changes and was higher during periods of low river discharge which correspond to higher sea surface inundation than periods of high river discharge. An Eulerian salt flux analysis was carried out to study the relative roles of advective and dispersive flux on transport processes. The residual or advective flux, dominates the transport within the system and marsh circulation in the upper reaches shows net inward movement along the channel and net outward movement over the marsh. Tidal flux dominates the dispersive flux over estuarine exchange flux and thus controls the horizontal dispersion. The horizontal dispersion coefficient was dependent on seasonal river discharge as the horizontal salinity gradient switches from a positive to a negative estuary causing very large and highly variable values during periods of high river discharge. Alternatively, the horizontal dispersion coefficient was more periodic and controlled by the spring/neap cycle, showing maxima on spring tides during the season of low river discharge and high sea surface inundation.

▼ Vibration and cavitation can be generated in many ways and serve many useful purposes. This study describes physical aspects of useful vibration and cavitation for a broad spectrum of applications at atmospheric or elevated pressures. After a review of available devices, hydrodynamic vibrating-body-in-pipe tools as described in patents by Ivannikov are identified as having a major potential and being largely unexplored. Major advantages of these tools are simplicity of construction, scalability, powerful effects and attractive frequency range for well cleaning applications. Self induced vibration with a free body colliding with the pipe wall causes alternating flow around the body with a water hammer effect that enhances the vibration and cavitation. Cavitation can thus be generated at lower flow rates and at higher backpressures than with passive tools such as orifices. Cavitational collapse at high backpressure creates exceptionally strong effects, giving access to novel applications. At backpressures where even water hammer enhanced cavitation ceases to exist, very strong vibrations persist to pressure levels encountered in deep wells. This unique dual enhanced vibration and cavitation behaviour of the tools is the key to vibrating-body-in-pipe technology for which the new name VibroCav was coined. The study focuses on VibroCav tools with balls, except for one series of tests with a so-called flip-flop body. Exploratory tests in a 350 bar test circuit in Assen lead to the design of a 50 bar laboratory closed test circuit installed in the 3ME lab in Delft with facilities to apply up to 10 bar backpressure and up to 40 bar pressure differentials over the tools. In the 50 bar test circuit many experiments were carried out, firstly with bottom supported balls in a straight pipe and secondly with hanging balls in a pipe with a conical outlet allowing remote adjustment of the gap between the ball and the pipe wall. The influence of water composition, gas content and various ball materials was tested. Selected high backpressure test were carried out with a 350 bar closed test circuit in Drachten. A total of 29 field trials on an industrial scale were carried out for cleaning the porous media around water and oil wellbores under widely varying conditions and 5 field trials were done to evaluate the potential of the technology for the removal of scale deposits in wellbores. The laboratory experiments with the 50 bar test circuit delineated various operational modes of the VibroCav tools as function of flow rate and backpressure with regimes designated as (i) vibration only, (ii) active cavitation always combined with vibration, (iii) no vibration and passive cavitation and (iv) no vibration and no passive cavitation. The vibration regime persists to the maximum backpressure that could be reached and probably to much higher pressures, however at high flow rate conditions and a narrow gap vibration ceases when the Re value increases beyond the point of drag reduction due to shifting of the boundary separation point (Re… Advisors/Committee Members: Witkamp, G.J., Kramer, H.J.M..
