In this paper we outline the hyperbolic system of governing equations describing one-dimensional blood flow in arterial networks. This system is numerically discretised using a discontinuous Galerkin formulation with a spectral/ element spatial approximation. We apply the numerical model to arterial networks in the placenta. Starting with a single placenta we investigate the velocity waveform in the umbilical artery and its relationship with the distal bifurcation geometry and the terminal resistance....

There are two mathematical models of elastic walls of healthy and atherosclerotic blood
vessels developed and studied. The models are included in a numerical model of global
blood circulation via recovery of the vessel wall state equation. The joint model allows
us to study the impact of arteries atherosclerotic disease of a set of arteries on
regional haemodynamics.
