Pulse wave propagation in a model human arterial network: Assessment of 1-D visco-elastic simulations against in vitro measurements

► We test the accuracy of the nonlinear 1-D equations of blood flow in large arteries. ► We compare wave measurements in a silicone tree with numerical predictions. ► 1-D modelling is able to capture the main features of pulse waveforms. ► Simulation of wall visco-elasticity significantly decreases relative errors. ► Energy losses at bifurcations have a secondary effect on pulse waveforms.
