An Experimental Study of Formation of Circulation Patterns in Laminar Unsteady Driven Cavity Flows Using Particle Image Velocimeter (PIV) Techniques
… in the high laminar to transitional range. Driven Cavity Flow is a classic fluid dynamics case often used for benchmarking of computational codes. Previous work has primarily focused on improving computational codes, experimental work is lacking and focused on obtaining steady state …

Efficient solutions of 2-D incompressible steady laminar separated flows
… two-dimensional incompressible laminar steady flows at moderate-to-high Reynolds numbers. The method uses an incremental multigrid method and an extrapolation procedure based on minimum residual concepts to accelerate the convergence rate of a robust block-line-Gauss-Seidel solver for the …

The large-eddy simulation of incompressible flows in simple and complex geometries
… the turbulent physics of an incompressible flow in simple and complex geometries. The Cartesian form of the governing equations was first verified, and then later used to investigate a three-dimensional shear-driven cavity flow. The investigation involved Reynolds numbers of 2000, 3200, 5000 …

Development of an efficient finite volume computational platform for the simulation of complex flows of complex fluids governed by the Rolie-Poly model
The flow of non-Newtonian fluids, also known as complex fluids, is an important area of fluid mechanics due to their applications in industries such as food processing, mining, chemical and plastic industries. It is therefore essential to understand the flow and general behaviour of such fluids. …

The Stability Properties of Some Rheological Flows
The stability of wall driven and thermally driven cavity flow is investigated for a wide range of viscous and viscoelastic fluids. The effect of inertia, elasticity, temperature gradients, viscous heating and Biot boundary conditions are of particular interest. Both destabilisation and bifurcation …

ILU and Machine Learning Based Preconditioning For The Discretized Incompressible Navier-Stokes Equations.
… Numerical experiments for model problems of a driven cavity flow, and flow over a backward-facing step illustrate the performance of one-parameter and two-parameter ILU factorizations as preconditioners. We also introduce a Machine Learning (ML) based approach for building ILU factorizations …

Least squares finite element methods for the Stokes and Navier-Stokes equations
… Finally, we compare numerical results for the driven cavity flow problem with some benchmark results reported in the literature.

An Approximation for the Twenty-One-Moment Maximum-Entropy Model of Rarefied Gas Dynamics
… to predict continuum and moderately rarefied flow offers many modelling and numerical advantages over traditional methods. The maximum-entropy family of moment closures offers models described by hyperbolic systems of balance laws. In particular, the twenty-one moment model of the …

High order stochastic transport and Lagrangian data assimilation
… tracer advection in a deterministic swirl flow, stochastic flow past a cylinder, and stochastic lid-driven cavity flow. We show that our schemes improve the consistency between reconstructed DO realizations and the corresponding MC realizations, and that we achieve the expected order of …

Chaos in Pulsed Laminar Flow
Fluid mixing is a challenging problem in laminar flow systems. Chaotic advection can play an important role in enhancing mixing in such flow. In this thesis, different approaches are used to enhance fluid mixing in two laminar flow systems. In the first system, chaos is generated in a flow between …

Quantitative methods to regulate angiogenesis: applications to cancer and cardiovascular disease
… element numerical method with the benchmark lid-driven cavity flow problem. Numerical simulations show that the Newtonian model gives similar velocity profiles in the 2-dimensional cavity given different height and width dimensions, given the same Reynolds number. Conversely, the SDF model gave …
