Fluid flow and slope stability model
… changes in the water saturation. A two-phase fluid flow model was incorporated to calculate the saturation and saturation changes in fractured and nonfractured soil and rock. A slope stability model was created to calculate the factor of safety. The fluid flow module executes for every time …

Fluid flow measurement using correlation techniques
… cross correlation method to measurement of flow under steady and pulsating flow conditions is investigated. The factors to be considered in applying this technique to different flow systems are discussed and its advantages over the conventional techniques are highlighted. The method involves …

MICA: Fluid Flow Over Varying Geometries
… and portable set-ups. A portable water flow visualization chamber was designed and prototyped for use in fluids courses to enable hands on opportunities in classes that are typically theory based. The initial prototype had a lower flow rate than expected, but was able to generate some …

Multigrid solutions of elliptic fluid flow problems
… and economic simulation of convection dominated flows. The use of a high-order approximation to the convective transport terms found in the governing equations of motion has been investigated in conjunction with an unsegregated smoothing technique. Results are presented for a sequence of problems …

Efficient High Order Ensemble for Fluid Flow
<p>"This thesis proposes efficient ensemble-based algorithms for solving the full and reduced Magnetohydrodynamics (MHD) equations. The proposed ensemble methods require solving only one linear system with multiple right-hand sides for different realizations, reducing computational cost and …

A Spectral Element Method for Viscoelastic Fluid Flow
… technique for solving incompressible Newtonian flows and viscoelastic flows of non-Newtonian fluids. In the numerical simulation of the incompressible Newtonian fluid in two dimensions, the spectral element approximations of the Stokes and Navier-Stokes equations are established, based on the …

Modelling the endothelial cell response to fluid flow
In vitro endothelial cells respond to fluid flow by elongating in the direction of flow. How the mechanical signal is transformed into an organised and directed response is poorly understood. The most studied and crucial aspects to this response are; actin filament alignment, mechano-transduction, …

Bioinspired Robust Underwater Behaviors Using Fluid Flow Sensing
The lateral line sense organ in fish detects fluid flow around its body, and is used to perform a wide variety of behaviors such as rheotaxis, wall-following, prey detection, and obstacle and predator avoidance. Currently there are no equivalent engineering analogues that can sense fluid flow …

Viscous Fluid Flow in Bifurcating Channels and Pipes
In the present thesis the flow of a viscous Newtonian fluid in a bifurcation of thin three-dimensional pipes with a diameter-to-length ratio of order O(epsilon) is studied. The model is based on the steady-state Navier-Stokes equations with pressure conditions on the in- and outflow boundaries. …

Nonlinear dynamics of three dimensional fluid flow separation
Flow separation (the detachment of fluid from a no-slip boundary) is a major cause of performance loss in engineering devices, including diffusers, airfoils and jet engines. The systematic study of flow separation dates back to the seminal work of Prandtl in 1904. He showed that a two-dimensional …

Optimal Linear Feedback Control for Incompressible Fluid Flow
Linear feedback control is considered for large systems of differential algebraic equations arising from discretization of saddle point problems. Necessary conditions are derived by applying the Maximum Principle and have the form of constrained Riccati equations. We consider two approaches for …

Fault rock evolution and fluid flow in sedimentary basins
… mechanisms involved in fault rock evolution and fluid flow associated with extensional faulting in upper crustal conditions. Intrabasinal fault rock evolution has been investigated in the Orcadian Basin, NE Scotland, which developed in Old Red Sandstone (ORS) times, soon after cessation of the …
