Abstract

This paper presents a one-dimensional model, based on Navier Stoke's equations, that predicts the blood pressure and flow in the larger arteries. The outflow con- dition is based on the assumption of a constant peripheral resistance, i.e. that the ratio between pressure and flow is constant. Simulations are carried out for two cases: 1 - the aorta is regarded as a single tapered tube, and 2 - the iliac bifurca- tion and part of the femoral arteries are included. 1 Introduction The major purpose of this study is to investigate the blood pressure and flow in aorta with special regard to the influence of the outflow boundary condition. First, we experiment with the aorta regarded as a single tapered vessel with the outflow boundary condition placed at the iliac bifurcation. We study how a change in t
