Computational Fluid Dynamics

■Research Interests

Parallel processing for CFD
Computational Fluid Dynamics (CFD) deals with the solution of fluid-dynamic equations on computers and the related use of computers in fluid-dynamics research. Recent successes in CFD are based on innovative numerical algorithms that discretize the continuous equations of fluid dynamics into a large number of algebraic or ordinary differential equations. These equations are then solved using currently available, large-memory, high-speed computers. Unfortunately, the rapid advances in both algorithms and hardware appear to be approaching some intrinsic limits. Current finite-difference, finite-volume, finite-element and spectral algorithms for solving partial differential equations have reached the point of diminishing returns in terms of trading off computational cost for accuracy. We are interested in new numerical algorithms optimized for parallel processing as well as old ones recast in parallel form. Though some of the current popular methods may be eclipsed because of the difficulty of constructing efficient parallel implementations, other models, better suited to the directions of parallel processing, will take over their role.
Flow visualization with computer graphics
Scientific visualization is a rapidly growing area in which efforts from computer graphics research and many scientific and engineering disciplines are integrated. Flow visualization is one of most challenging areas in scientific visualizations. For 3D flow visualization a variety of techniques can be used, such as drawing particle trajectories, vector plots, contouring, and particle tracing, each with its own advantages. The main problem in 3D flow visualization is the comprehension of the spatial structure of a flow field using images or animated sequence of images. Our approach is to combine the technique of particle tracing with surface interpretation combining the advantages of both. We achieve spatial information with surface shading and transparency, and motion information with a moving texture.
Biofluid Mechanics
Detailed knowledge of flow patterns and wall shear stresses in regions of non-uniform conduit geometries such as arterial bifurcations, bends, stenosis and aneurysm is of the utmost importance for clarifying of the link between the local fluid dynamics and the development of atherosclerosis. Flow of blood through such sites is not simple, due to the complex geometry of blood vessels, the pulsatile nature of the flow, the distensibility of the arterial wall and the non-Newtonian characteristics of the blood. Finite element methods have the great advantage of offering geometrical flexibility, so that complex geometries can be modelled with relative ease. However, these methods are sophisticated and very expensive for a three-dimensional problem, since it has proved difficult to produce an economical three-dimensional finite element fluid flow code. We are interested in solving the Navier-Stokes equations governing three-dimensional, pulsatile, non-Newtonian, incompressible flow by an efficient finite element method.
