Abstract:

"Compressible fluid dynamics of flow through plain-faced long orifices was investigated with the hope of gaining insight into the fluid dynamics of tip leakage flow. The Reynolds number range investigated was greater than 10*. Measurements were made of the discharge coefficient as a function of back pressure ratio for a sharp-edged orifice and long orifices with an l/d from 1/2 to 8. The discharge coefficient measurements indicate the mass flow rate in an orifice with an l/d of approximately 2 is the largest and the flow rate in a sharp-edged orifice is the smallest for pressure ratios greater

Abstract:

This thesis explored the potential of utilising Computational Fluid Dynamics simulations to design and improve a perfusion bioreactor for practical mesenchymal stromal cell experimentation. This method of simulations allowed for an in-depth analysis of the microfluidic nature within the custom-designed parallel plate flow chamber, creating the conditions the 3D PCL Scaffold carrying these cells would undergo. The focus on the simulated velocities and resulting shear stresses upon the scaffold surfaces (cells attachment site) ensures the cells survive. Further investigation was taken to improve

This thesis presents the numerical solution for two-dimensional incompressible viscous flow over a rigid bluff body which is elastically supported or alternately undergoing a specified harmonic oscillations. Solutions for the related associate flow in which the body is at rest in a two-dimensional incompressible time-dependent viscous flow have also been -obtained. This work is an extension of the work by Pattani [19] to include the effect of a steady far field flow on an oscillating body.

Transport phenomena inside a low consistency disc refiner were experimentally investigated. A transparent refiner door was designed and fabricated with four acrylic viewports enabling plate-scale and groove-scale visual observation. High speed video, ultra-violet fluorescent tracer particles and a MATLAB program were used to perform particle tracking velocimetry to gain further understanding of the flow field. The experimental working fluid under study was water. The effects of refiner operating parameters on the flow field were of particular interest. Refiner flow rates were varied from 300 t

Abstract:

The current work is a study of wax deposition, a phenomenon that is one of the main flow assurance problems faced by the oil industry, affecting numerous oil companies around the world. Wax deposition can result in the restriction of crude oil flow in the pipeline, creating pressure abnormalities and causing an artificial blockage that can lead to reduced or interrupted production. Wax can precipitate as a solid phase on the pipe wall when its temperature drops below the wax appearance temperature (WAT). The aim of this research is to study in a lab rig the influence of some of the factors tha

Tortuous microchannels have attracted increasing interest due to great potential to enhance fluid mixing and heat transfer. While the fluid flow and heat transfer in wavy microchannels have been studied extensively in a numerical fashion, experimental studies are very limited due to the technical difficulties of making accurate measurements in micro-scale flows. This thesis provides insights into thermohydraulics of tortuous microchannels by developing experimental techniques and performing systematic visualisation and heat transfer experiments.

One of the important scientific research focuses worldwide has been on the study of behavior of materials at micro and nano-scales. Continuing theoretical and technological development in this area has led to the development of many biological and engineering devices and systems which involve fluid flow through micro-channels, referred to microflows. Typical examples include fuel cells, drug delivery systems and energy conversion devices.As the functional characteristics of micro-systems depend, to a large degree, on the behavior of fluid flow in the micro-channels, it is extremely important t

Abstract:

This thesis describes a computational model for an initial/pre-collecting lymphatic network and a study on valvogenesis (formation of valves in the lymphatics during embryonic development). The computational model was applied to rat mesenteric lymphatic networks (19- and 163-segment) with sparse secondary valves. The network was simulated with these secondary valves being operational and non-operational. Sensitivity of parameters like the vessel stiffness, interstitial resistance, and the availability of primary valves, on the cycle-mean outflow-rate from the 19-segment network was considered.

Abstract:

Air quality in urban and industrial complexes is of great importance owing to the many implications on human and environmental health. Air pollution in built-up areas is typically associated with traffic exhaust emissions. High pedestrian level concentrations are the result of a non trivial combination of pollutant sources, climate and city morphological configurations. The increase of urbanisation puts a strain on city resources, resulting in increased use of transport and a denser and more compact urban fabric. The consequence of such a change in city morphology exacerbates current human air

The pressure drop was measured using 23 bottom tapping points along a 34 m test section. The results were compared with six well known pressure drop models; these models did not allow for diameter size effect, it was therefore not surprising that good agreement was not achieved.

Abstract:

The study and modelling of two-phase flow, even the simplest ones such as the bubbly flow, remains a challenge that requires exploring the physical phenomena from different spatial and temporal resolution levels. CFD (Computational Fluid Dynamics) is a widespread and promising tool for modelling, but nowadays, there is no single approach or method to predict the dynamics of these systems at the different resolution levels providing enough precision of the results. The inherent difficulties of the events occurring in this flow, mainly those related with the interface between phases, makes that

Abstract:

Understanding the hydraulic properties of rock fractures is an issue of great importance in fields such as petroleum engineering, groundwater hydrology, and underground waste isolation. Traditionally, models of fluid flow through rock fractures have been based on the cubic law, which asserts that the local value of the fracture transmissivity is equal to /i^/12, where h is the fracture aperture. The local cubic law is mathematically equivalent to assuming that flow in the fracture is governed by the Reynolds lubrication equation. However, this equation is only applicable if the aperture does n

Abstract:

Numerical calculations were performed over a variety of two-dimensional rib roughness configurations in which the ratio of flow depth to roughness height was varied from 1.1 to 40. Periodically fully developed flow was achieved by employing periodic boundary conditions and the effect of turbulence was accounted for by a two-layer model. These calculations were used to test the hypothesis that any rough wall resistance may be reduced to an equivalent wall shear stress located on a plane wall. The position of the plane wall is determined by a novel method of prediction obtained by consideration

However, the large degree of segregation of the phases obtained at the outlets of a T-junction for certain flow rates and geometries, has encouraged Industry and researchers to exploit this simple device as a partial phases separator.

The mechanisms which determine the noise floor of the interferometer are examined and minimisation procedures are defined. A prototype instrument is described which has a dynamic range of 60 dB over

Molecular dynamics (MD) and computational fluid dynamics (CFD) allowresearchers to study fluid dynamics from two very different standpoints. From a microscopic standpoint, molecular dynamics uses Newton's second law of motion to simulate the interatomic behavior of individual atoms, using statistical mechanics as a tool for analysis. In contrast, CFD describes the motion of a fluid from a macroscopic level using the transport of mass, momentum, and energy of a system as a model. This thesis investigates both MD and CFD as a viable means of studying viscous flow on a nanometer scale. Specifica
