▼ This thesis addresses the performance of jointed pipelines subject to ground deformations triggered at a large scale by earthquakes and a construction-related scale by tunneling. Understanding and quantifying jointed pipeline response at these scales allows for better design, operational management, and risk assessment of underground infrastructure, where cast iron (CI) and ductile iron (DI) pipelines in the U.S. account for approximately 75% of water distribution systems. The thesis covers the response of DI and molecularly oriented polyvinyl chloride (PVCO) pipelines to earthquaketriggered soil movement as well as CI and DI pipeline response to tunneling. A series of specially designed four-point bending experiments and 3D finite-element (FE) simulations were performed to characterize DI push-on joints commonly used in water distribution systems to develop a relationship between the rotation and axial pullout at both metal binding and first leakage. The results of uniaxial tension and onedimensional compression tests on the elastomeric gaskets in DI push-on joints were implemented in numerical models that show joint leakage to be independent of load path, with a unique pressure boundary that predicts leakage for many combinations of axial pullout and rotation. The increased circumferential strength, reduced pipe wall thickness, and enhanced cross-sectional flexibility of PVCO pipelines was evaluated through the characterization of PVCO material properties, axial joint tension and compression tests, four-point bending tests, and a full-scale fault rupture experiment. A nominal 150-mm (6-in.)diameter PVCO pipeline is able to accommodate significant fault movement through axial tensile and bending strains in the pipe in combination with modest levels of axial slip at the restrained joints. Relatively large levels of axial strain in the low modulus PVCO material, which varies between 1% and 2% at pipeline failure, are able to sustain substantial extension and compression from ground movements. Soil/pipeline interaction modeling was performed for vertical and horizontal ground movements caused by tunneling in jointed CI and DI pipelines perpendicular to the tunnel centerline that (1) extend beyond the width of the settlement profile and (2) connect through 90° tees with a pipeline parallel to the tunnel. The modeling incorporates the results of large-scale laboratory tests. Guidance is provided for design and the identification before tunneling of potential difficulties. In particular, CI tees are at high risk when subject to tunneling induced soil movement, whereas DI pipelines and tees have sufficient capacity to accommodate high levels of tunneling related ground deformation. iv Advisors/Committee Members: O'Rourke,Thomas Denis (chair), Stewart,Harry Eaton (committee member), Ingraffea,Anthony R (committee member).

▼ Cast-iron water mains are still in use in water distribution systems across North America. These pipes are now reaching the end of their expected service lives and are becoming a concern to water utilities. Large-diameter water mains (defined as water mains with a diameter greater than 500 mm (20”)) are particularly important because of they can entail severe consequences when they fail. A physical model is presented to estimate the time-dependent factor of safety and probability of failure of large-diameter cast-iron water mains. Failure is assumed to occur by longitudinal cracking caused by tensile hoop stress and a reduction in the strength of the pipe due to corrosion pitting. Six sources of loading are considered in the model, including: earth load, live load, frost load, internal water pressure, and the curvature caused by the live load. The model is used in a two-part sensitivity analysis to determine the influence of each input of the model outputs. The first part of the analysis is a one-way deterministic sensitivity analysis of all 28 input variables. This identified six variables as having a high impact: the pipe wall thickness, the pitting depth scaling constant, the corrosion rate inhibition factor, the fracture toughness, the constant S in the residual tensile strength calculation, and the pipe diameter. The second part is a stochastic sensitivity analysis to further investigate the sensitivity of the model to those variables identified in the deterministic analysis. The mean factor of safety and probability of failure were determined to be sensitive to the pipe wall thickness, corrosion rate, and the constants used to calculate the residual tensile strength, but were relatively insensitive to the diameter of the pipe. A case study of the City of Hamilton water distribution system was performed to characterize the failure of 20 large-diameter cast-iron water mains. Due to the uncertainty in the accuracy of the model, the pipes were assigned ranks relative to each other rather than an absolute probability of failure. The diameter, burial depth and soil type were all determined to have an effect on the ranking of each pipe.

▼ Ductile iron (DI) pipes have been used for the conveyance of drinking water in drinking water distribution systems over the past several decades. It has been estimated that almost half of all new water mains installed in North America are DI pipes. Although DI pipe itself is resistant to chemical permeation, the polymeric gaskets that join and seal the pipe segments are reported to be susceptible to permeation by organic contaminants. Pipe-drum, diffusion cell experiments, and numerical simulations were conducted in this research to obtain a faster mean to evaluate possible permeations through DI gaskets. Of the five types of gasket materials tested using the gravimetric sorption test, ethylene-propylene-diene monomer (EPDM) had the highest sorption of gasoline, while fluoroelastomer rubber (FKM) exhibited very low sorption of gasoline. The sorption test results suggested that the least to most resistance to permeation of premium gasoline for the five gasket materials were EPDM, styrene-butadiene rubber (SBR), chloroprene rubber (CR; neoprene), acrylonitrile butadiene rubber (NBR), and FKM. A typical gasket was found to be made of two portions, the heel and the bulb, of the same polymer but different formulation. Gravimetric sorption tests suggested that the heel portion of all gaskets may be more resistant to permeation than the bulb making it the limiting step for permeation of organic compounds in gasoline. Pipe-drum experiments showed that SBR gasket had the highest permeation rates of benzene, toluene, ethylbenzene, and xylenes (BTEX), followed by CR, EPDM, and NBR. With regards to threats to drinking water under water stagnation conditions in the pipe, the 5 μg/L maximum contaminant level (MCL) for benzene will likely be exceeded during an 8-hour stagnation period for SBR gaskets in contact with free-product premium gasoline. NBR gaskets were found to be sufficiently resistant to permeation by benzene or other BTEX compounds in gasoline and the benzene concentration is unlikely to exceed EPA MCLs. Assessment based on data from the pipe-drum experiments suggested that when there is flow of water in the pipe, benzene and other BTEX compounds in gasoline will not exceed EPA MCLs. A diffusion cell device was developed to obtain diffusion coefficients of BTEX compounds for various gasket materials under controlled conditions. Using curve fitting of the permeation data by numerical modeling, the diffusion coefficients of BTEX compounds through SBR and NBR gasket materials was found to range from 10-7 to 10-8 cm2/s. The steady-state permeation rates were found to correlate in a linear relationship with thickness while the diffusion coefficients were found to be invariable to the thickness of the polymer tested (2 mm to 5 mm). The diffusion cell provided a rapid, inexpensive, and relatively well-controlled means to study permeation of polymeric gasket materials for DI pipes and the data obtained were used to model benzene permeation of the pipe-drum experiments. The permeation of benzene through a 4-inch SBR gasket of…

▼ An experimental investigation of smooth wall, fully developed turbulence was undertaken in a high aspect ratio channel flow facility and a circular pipe flow facility. High fidelity hot-wire measurements of streamwise velocity with carefully matched experimental and anemometer parameters were made in order to facilitate the direct comparison of the two internal flows over a range of Reynolds numbers. Measurements where the inner scaled hot-wire sensor length was held constant at 22 with length-to-diameter ratio greater than 200 revealed that channels and pipes have similar streamwise mean velocity distributions in the near wall and logarithmic regions, with pipe flow mean velocity profiles showing a larger deviation from the log law in the outer region compared to the channel flow. The turbulence intensity profiles were found to match well throughout the flow, and importantly, the near wall peak in turbulence intensity was shown to increase with friction Reynolds numbers up to 3000. Further, the centreline turbulence intensity in both flows was also shown to increase with increasing Reynolds number in a manner consistent with data presented in the literature. The one-dimensional pre-multiplied energy spectra revealed that the near wall peak in turbulence intensity grows due to the increasing energy contribution of the large scales of turbulent motion, however, whilst the spectral energy distribution is similar in channels and pipe for the near wall and overlap regions, the channel flow maintains energy at longer wavelengths than the pipe flow at the centreline, indicating that there are some subtle yet important difference between the core regions of these two flows. Measurements where hot-wire sensor length and aspect ratio were systematically varied reveal that increasing sensor lengths lead to attenuation of an increasingly large range of small scales, whereas an insufficient aspect ratio causes the measured energy to be attenuated over a very broad range of scales. It was demonstrated that the competing effects of spatial filtering and increasing Reynolds number may be the cause for the conflicting reports regarding the Reynolds number dependency of the near wall peak in turbulence intensity. Spatial filtering effects were found to be no different in channels and pipes for the range of sensor lengths and Reynolds numbers investigated. While the effect of spatial filtering diminished when moving away from the wall such that little to no attenuation was observed in the outer region, an insufficient sensor aspect ratio appeared to attenuate energy over a broad range of scales in both the inner and outer regions of the flow. It was determined that a sensor aspect ratio greater than 200 is sufficient for the pure platinum hot-wires used in this study which is consistent with the findings of Ligrani & Bradshaw (1987). In a further set of experiments, an array of multiple wall…

▼ This thesis addresses the performance of ductile iron (DI) pipelines with restrained axial slip joints subject to earthquake-induced ground deformation. DI pipelines account for 23% of U.S. water distribution systems (US.EPA, 2013), and have been used extensively for replacing aging cast iron (CI) pipelines. Under earthquake-induced ground deformation a jointed DI pipeline is vulnerable primarily to joint pullout and excessive joint rotation. Improvements in pipeline technology have led to the development of DI pipelines with restrained axial slip joints that move axially and rotate to conform to differential soil movements, but are restrained from pullout without leakage and loss of structural integrity. A series of large-scale experiments was performed on DI pipelines with restrained axial slip joints to characterize tensile strength properties, direct axial compression and tension, moment vs rotation characteristics, soil axial restraint, and performance in response to fault rupture. Large-scale tests were performed primarily on 6-in. (150-mm)-diameter DI pipelines, but also included direct tension and bending tests on 12-in. (300-mm)-diameter DI pipelines. The direct compression tests show either leakage or irrecoverable deformation in the form of large rotation at loads equal to or slightly higher than load consistent with the proportional limit stress of DI pipe. The direct tension tests show that tensile failure of the pipeline depends on the locking mechanism of the joint. Joints that use full circumferential locking rings generate the highest resisting force. Failure and leakage under tension with these features occurred as DI ring shear fracture and bell fracture. In contrast, joints that use locking segments mobilized lower pullout force. Failure and leakage of joints with locking segments occurred as local deformation at the spigot caused by load concentration at the locking segments, allowing the weld bead to slip past the locking segments and cause leakage. Large-scale fault rupture tests provide a comprehensive and detailed understanding of the sequence of joint movements, combined axial pullout and rotation at each joint, and the actual axial forces influenced by longitudinal frictional resistance and axial resistance to movement at the joints. The longitudinal frictional forces are controlled by at-rest (Ko) conditions, which set the initial state of stress along the pipeline near the north and south ends of the split basin, and the conditions of maximum lateral soil reaction during fault rupture, which establish the maximum longitudinal frictional resistance for the pipeline in the vicinity of fault rupture. The joint axial resistance model proposed in this work is obtained from the expression for face resistance of the leading edge of a jacked pipe proposed by Meskele and Stuedlein (2015) from the work of Weber and Hurtz (1981). The model is used to predict the axial resistance from a restrained axial slip joint for DI pipe and the pullout restraints of PVCO and PVC pipelines.

▼ As vast networks of high pressure buried energy pipelines traverse North America and other continents, the stability of such essential buried infrastructure must be maintained under a variety of earth loading conditions. The pipe-soil interaction and the longitudinal behaviour of buried pipes due to relative ground movements is poorly understood. This thesis presents full scale testing and numerical modeling of steel and Glass Fibre Reinforced Polymer (GFRP) pipelines to better understand the flexural performance of buried pipes subjected to lateral earth movement. For the experimental phase of the study, a series of pipe bending experiments have been conducted on 102 mm nominal diameter and 1830 mm long steel and GFRP pipes buried in dense sand. Pipe loading was carried out by pulling pipe ends using two parallel cables attached to a spreader beam outside the test region, using a hydraulic actuator. The different tests covered burial depth-to-diameter (H/D) ratios of 3, 5 and 7. During the steel pipe testing phase, special consideration was given to assess the effect of boundary limits, friction within the pulling mechanism, and consistency of results using repeated tests. For the GFRP pipes, the experimental work investigated the effect of the laminate structure of the pipes, including both cross-ply and angle-ply laminates. Test results showed that burial depth significantly influenced the ultimate pulling forces, longitudinal strains, and pipe net deflection at mid-span. The results were also compared between the two types of pipes. The failure mechanism for all tests was consistently governed by soil failure, except for the angle-ply GFRP pipe that failed at a burial depth of H/D=7. For the numerical analysis, the study presents the development and verification of two and three-dimensional numerical models including material constitutive models for both the pipe and for the soil using a stress-dependent modulus. Calculations are presented for different burial depths and are compared to experimental data. It was shown that the numerical model can successfully capture the pipe-soil interaction behaviour for both pipe types in terms of load-displacement responses and net bending deflection. Also, the effect of material variation and laminate structure were in agreement with test data.

Dans le cadre d’une contribution à la modélisation des caloducs oscillants, le modèle mis en place se résume à une bulle seule se déplaçant dans un tube de dimension capillaire.Une densité volumique de chaleur est considérée dans la paroi du capillaire, et la température de référence considérée n’est pas la température de saturation de la phase vapeur,mais la température extérieure au tube ce qui permet la variation de la température de saturation dans le temps et une meilleur adéquation du modèle avec la réalité. La résolution du modèle est effectuée par étapes selon la technique de perturbation du domaine,et les effets physiques de moindres importances peuvent être ajoutés au problème simplifié, en particulier les effets inertiels. Cette résolution a permis de définir une nouvelle corrélation portant sur la hauteur de film déposé par le bouchon liquide en mouvement en fonction du nombre capillaire et d’un nombre d’évaporation représentant l’intensité du chargement thermique. Ce modèle permettra aussi d’étudier l’influence réciproque des champs de vitesse et de température sur le bouchon de liquide devant le ménisque en déplacement. La résolution du problème associé à la partie arrière de la bulle met en évidence la formation d’un bourrelet de liquide entre le film de liquide déposé à la paroi et le ménisque arrière. La taille de ce bourrelet est fortement dépendante de la densité de flux de chaleur imposée à la paroi. Dans le cas o`u le ménisque arrière remouille un film adsorbé laissé à la paroi après assèchement du film, la ligne triple présente des ondulations axiales dues à son déplacement, et non au chargement thermique. La densité de flux de masse évaporée à l’interface liquide-vapeur entraîne une modification non seulement de la température de saturation, mais aussi de la masse de la bulle. Un modèle thermodynamique de la phase vapeur a ´et´e mis en place pour étudier les paramètres importants influençant les variations temporelles des caractéristiques géométriques et thermodynamiques de la bulle.

The model of a single bubble moving in a capillary tube is written as a contribution to the modeling of Pulsating Heat Pipes. A constant heat load is considered at the wall, and the reference temperature of the problem is defined to be the outside medium temperature, which is closer to reality, and thus allowing the saturation temperature of the vapor phase to vary. Using domain perturbation techniques, a step-by-step resolution ofthe model is implemented, allowing minor physical effects to be taken into consideration,for example the inertial effect on the receding meniscus. A new correlation is proposed on the thickness of the liquid film deposited by the receding meniscus, by means of the capillary number and an evaporation number representing the thermal condition. The velocity and temperature fields in the liquid plug ahead of the meniscus can also be obtained. The resolution of the problem associated with the rear-end of the bubble,where the rear meniscus advances on either a micrometric liquid film or an…

▼ For utility trench backfill compaction, compaction-induced earth pressure in the backfill zone and deformation along the pipe are two important issues to be addressed. Backfill materials should be adequately compacted to lock the pipe in place and reduce potential settlement from external loading (e.g., traffic loading). On the other hand, excessive backfill compaction from compaction equipment may damage the pipe. Backhoe-mounted hydraulic plate compactors (hoe-packs) have been increasingly used for soil compaction in trenching, street repairing, or site preparations. Comparing to traditional compaction tools such as roller compactors, hoe-packs are advantageous for utility trench backfill compaction as they can be operated by the backhoe operator and requires no lifting of compaction machine during compaction process. However, uncertainty remains with regard to the maximum lift thickness to consistently achieve desired compacted dry mass density by hydraulic plate compactors. The large impulse energy and down pressure exerted by hydraulic plate compactors also raise concerns on potential damages to utility pipes. The objective of this study is to assess the capability of a hoe-pack for utility trench backfill compaction. Field tests were conducted to investigate the effect of hoe-pack on compacted dry mass density, compaction-induced earth pressures, and compaction-induced strains in pipe. Different values of lift thickness and pipe materials were used. Compaction tests using hand-held vibratory roller compactors which followed the specifications of the Pennsylvania Department of Transportation (PennDOT) were conducted as a control set. It is concluded that the hoe-pack used in this study can consistently achieve relative densities above 100% of the Standard Proctor Density (SPD) with a lift thickness of 8 inches or 12 inches. However, the hoe-pack is not able to consistently achieve relative densities above 100% of SPD 12 inches below the compacted surface when the lift thickness is 18 inches or greater. Comparing the performances of the hoe-pack and vibratory roller compactor used in this study for a lift thickness of 8 inches, the hoe-pack is more efficient in performing compaction. The hoe-pack used in this study is likely to induce higher dynamic earth pressures in the backfill zone, but may not induce higher static earth pressures depending on the pipe material and diameter. The hoe-pack used in this study generally induces similar strains along pipe as the vibratory roller compactor does. For the hoe-pack used in this study, the static earth pressures in the backfill zone are relatively insensitive to lift thickness, whereas the dynamic earth pressures may decrease as the lift thickness increases, depending on the pipe. The effect of lift thickness on strains developed along pipe also depends on the pipe. Advisors/Committee Members: Tong Qiu, Thesis Advisor/Co-Advisor.

▼ Fatigue failures of welded piping joints are continued to be the majority of the failures in the nuclear power plants (NPPTs), resulting in unscheduled plant downtime and financial loss. This study investigates the influence of ratcheting on the fatigue failure of the welded piping joints. Many studies on the phenomenon of strain ratcheting have been conducted at the macroscale but not in the microscale. This study presents results on the microstructure evolution of the heat affected zone under cyclic loading. Four welded piping specimens are subjected to displacement-controlled cyclic loading with different number of cycles. Microstructural evolutions of the piping material coupons conditioned by various temperature cycles to simulate HAZ materials are also investigated. The coupons are subjected to three different types of fatigue loading cycles, uniaxial strain-controlled, biaxial ratcheting, and uniaxial force-controlled before the microstructural investigation. The stress response of welded pipe specimens showed initial cyclic hardening until 20 cycles followed by softening, and strain ratcheting was observed at the weld toe. Microstructure at the weld toe showed various dislocation types under different number of cycles. More cell and wall structures were formed with changing volume fraction of each type of substructure as the number of fatigue cycles increases. Dislocation density measured at weld toe initially increased and then decreased until failure, which was attributed to cyclic hardening and softening. More heterogeneous dislocations were noted near the weld toe in contrast to more planar slip away from the weld toe. Cyclic hardening and softening are observed during cyclic loading of coupons. Stress amplitude responses show decrease in amplitude with increase in heat-treatment temperature under uniaxial strain-controlled tests. Before fatigue, heterogeneous dislocation structures are not visible, but various dislocation structures are observed after fatigue cycles; these include planar dislocations, dislocation cells, ladder like structures, tangles, dislocation walls as well as stacking faults. Percent of cell structure increases as the planar slip and tangles decrease with increasing number of cycles in both unconditioned and 800ËšC heat-treated materials. However, high proportion of planar slip remains even though cell structure increases in the 1050ËšC heat-treatment coupons. Dislocation density increases during cyclic loading where stress amplitude initially increases followed by decrease with progressive cycles. Dislocation cell size was inversely proportional to cyclic hardening. Ratcheting strain was observed when positive mean stress applied to a coupon under uniaxial force-controlled cycles. Dislocation structures were similar for both ratcheting and non-ratcheting coupons. However, cell and wall structures were better defined in non-ratcheting specimen while higher dislocation density is noted in ratcheting specimens. Under biaxial ratcheting cycles, all specimens exhibited dislocation… Advisors/Committee Members: K.L. Murty, Committee Chair (advisor).

▼ The trenchless technology known as pipe ramming for construction of culverts and buried pipes under roadways or other infrastructure has gained significant popularity due to its cost-effectiveness and ability to alleviate surface disruptions associated with open-cut trenching. Although the experience with pipe ramming is increasing, there has been remarkably little technical guidance available for engineers to appropriately specify aspects of a pipeline or culvert installation, including the planning of feasible layouts, rates of penetration, pipe diameters, and hammers. This research provides a comprehensive engineering framework for evaluation of culvert installations at the planning phase to address the gaps in knowledge associated with pipe ramming. Presently there are no existing and proven techniques for prediction of settlement, vibration, driving stresses, soil resistance to ramming, and drivability for pipe ramming installations. This study has adopted existing drivability, soil resistance, settlement, and vibration prediction models from pipe jacking, microtunneling, and pile driving models and examined their applicability in pipe ramming installations, resulting in new and technology-specific design guidance. The development of this comprehensive engineering guidance is based on engineering calculations empirically tuned using a database of actual performance measurements. Field observations of five production installations and a full-scale experiment were conducted to form the performance database employed to understand the mechanics associated with pipe ramming installations, ranging from vertical ground movements, ground vibrations, and installation performance. Settlement prediction was evaluated using the inverted normal probability distribution based models, and these methods over-estimated the observed settlements close to the center of the pipes and under-estimated settlements at radial distances away from the pipe. A pipe-ramming-specific hyperbolic model was developed for better prediction of the vertical settlement induced by pipe ramming in granular soils. Attenuation of observed pipe ramming-induced vibrations was modeled using a simple semi-empirical approach, and the calibrated model resulted in reasonable predictions of the ground vibrations for granular soils. The static soil resistance to ramming was evaluated using the traditional quasi-static pipe jacking models and the models resulted in inaccurate predictions for instrumented pipe ramming installations. Therefore pipe ramming-specific static soil resistance models were developed for both the face and casing resistance in granular soils. Principles of stress wave theory routinely applied in the drivability analyses for pile foundations were adopted for the evaluation of the dynamic response pipes during ramming. Reliable estimates of the static soil resistance and dynamic soil parameters were obtained through signal matching processes. Data-informed drivability analysis were performed to simulate the magnitude of… Advisors/Committee Members: Stuedlein, Armin (advisor), Istok, Jack (committee member).

▼ Centrifugal irrigation pumps discharge fluids at high velocities that must be slowed to minimize energy losses due to friction. Pipe expansions make the transition to larger pipes associated with slower velocities. Expansions convert the upstream velocity head to static head in the downstream pipe. The transition to a larger pipe is commonly an abrupt or single-stage conical pipe expansion. Two-stage conical pipe expansions have been shown to be more efficient and a potential alternative. Four two-stage pipe expansions using standardly available materials were constructed and tested at common irrigation flow rates. These expansions require less space and cost less than optimum two-stage expansions. Pressure change across the pipe expansions were measured. The calculated head loss coefficients were compared to published values of abrupt, single-stage, and optimum two-stage pipe expansions. Head loss coefficients for the 50 - 100 mm and 75 - 150 mm two-stage expansions averaged 0.32 and 0.28 respectively. Loss coefficients for the 100 - 200 mm and 125 - 250 rim two-stage expansions averaged 0.16 and 0.17 respectively. The two-stage expansions operated more efficiently than abrupt and single-stage expansions and were economically practical for many pumping situations. The 50 - 100 mm two-stage expansion was only a slight improvement over a single-stage welding cone expansion. The fitting was economical as electricity prices rose over $0.05/kWh for crops requiring 3000 annual operating hours. The larger fittings became progressively better. The 75 - 150 mm expansion became economically practical at $0.03/kWh when operating more than 1,600 hours. The 100 - 200 mm and 125 - 250 mm two-stage fittings were always practical. Beginning with the 75 - 150 mm size and increasingly with the next two larger sizes, optimum two-stage fittings became economically competitive. Optimum two-stage expansions operated most efficiently, but because of their high cost were only practical for high electricity costs and long irrigation seasons. The three largest two-stage expansions tested are improvements over abrupt or single-stage expansions when constructing a pump discharge. Replacing an existing, less efficient expansion may not be cost effective because the existing fitting cost is lost. While only a small part of an irrigation system, these two-stage expansions can improve system performance with little extra cost and without requiring difficult to obtain components.

The way in which mean strain affects the turbulent structures is imperative to understand various natural flows such as flow over a hill, the flow of a river in the delta, jet streams in the upper atmosphere etc. Further, it also has industrial implications viz; flow over bodies such as airfoil, turbomachinery, gas pipelines. The strained pipe flows, in particular, have huge engineering interest due to its prevalence in industrial fittings wherein a larger pipe diameter is connected to a smaller one and vice versa. This subject also has a fundamental interest as strain highlights the interaction of various scales of turbulence. This scale interaction essentially dictates transfer of energy in turbulence and hence is fundamental in understanding turbulence dynamics itself. The present work deals with the experimental study of the response of pipe turbulence to axisymmetric, irrotational strain using high-resolution planar Particle Image Velocimetry (PIV). A mildly rapid strain (s^*s ~ 3.2) is imposed on turbulence via a spatial contraction. It is seen that turbulence is suppressed upon straining. As a response to mean strain, transverse Reynold stress increases at the expense of streamwise Reynolds stress and anisotropy is induced in the turbulence. Despite strain being only mildly rapid, Rapid Distortion Theory (RDT) is found to predict the correct trend of normal Reynolds stress although traverse Reynolds stress is over-predicted. The effect of strain on different scales of turbulence is discerned. The large scales of turbulence are seen to get compressed in the radial direction although they do not get affected significantly in the streamwise direction. Near-wall coherent structures which were initially inclined w.r.t. the wall are seen to get aligned with the flow as they also get severely compressed in the radial direction. On the other hand, the small scales of turbulence are found to be spatially organised in the form of sheets or layers. Upon straining, these sheets are found to get aligned with the mean flow. Further, they get elongated in streamwise and compressed in the radial direction. It is observed that the small scales are more severely distorted than the large scales upon staining inside the contraction. At the Reynolds number (Re) range employed in this thesis, there is no substantial difference in which turbulence is strained inside the contraction at disparate Re. Downstream of the contraction, at the axis of the pipe, the anisotropy of Reynolds stress is found to recover slowly. Further, this relaxation is seen to be Re dependent with higher Re turbulence relaxing slightly faster.
