Abstract

Modelling and simulation of the human arterial tree - a combined lumped-parameter and transmission line element approach M. Karlsson Applied Thermodynamics and Fluid Mechanics Department of Mechanical Engineering, Linkoping University, Linkoping, Sweden 1 Introduction Computer models of the arterial tree has been a goal in bio-fluid dynamics ever since the advent of the digital computer. Over the years several con- tributions have been made and increasingly more elaborate models of the systemic arterial tree have been developed in order to gain a better insight into the hemodynamics of man. This paper describes a model of the arterial tree with distributed pa- rameters which has been developed in order to quantify hydro-mechanical effects in the arterial system. Any such model must resolve the characteris- tic features of the arterial tree such as distributed resistance and the ability to incorporate local variations in segrnental compliance. The topology of the arterial
