Simulation of Arbitrary Shaped Boundaries for Hemodynamic Studies

Abstract

The studies involve the solution of a system of non-linear, partial differential equations known as the Navier-Stokes equations. A particular requirement for hemodynamic studies is that a solution technique exists which allows flexible, arbitrarily shaped, no-slip boundaries to be defined in the model being studied. The technique which is developed in this report allows that kind of definition. It is a finite difference technique, based on the Marker and Cell method. Techniques for applying interactive computer graphics to the solution of hemodynamics problems involving flexible, arbitrarily shaped, no-slip boundaries are demonstrated for a particular problem. This problem involves the study of blood flow through a ball-type prosthetic heart valve. (Modified author abstract)
