Abstract

Hemodynamics is the study of blood flow or the circulation. In the present talk we will firstly illustrate an importance of studying hemodynamical flows and formulate a mathematical model based on basic conservation laws (conservation of mass and momentum). We will discuss existence of the so-called weak solutions and propose a suitable numerical technique to simulate blood flows in elastic vessels. Finally we will illustrate the behaviour of numerical schemes on a series of numerical experiments. We also show the results for hemodynamic wall parameters; the wall shear stress and the oscillatory shear index that are of special interest for medical doctors.

The present research has been done in cooperation with A. Hundertmark-Zauskova (Mainz) and G. Rusnakova (Kosice / Mainz).
