Abstract

This is an initial study of overall prediction exercise to simulate blood flow through three-dimensional arterial bifurcations, ASTEC code is used with finite element grid definition and finite difference solution methods. Results are compared with laboratory measurements of Ku and Liepsch for T-junctions. Comparison is excellent for two-dimensional steady flow tests, and very good for three-dimensional pulsatile flows.
