Improving Sonic Rarefactions in Elastic Vessels: Application to the Tourniquet Manoeuvre

Abstract

Elastic vessels like arteries and specially veins are prone to sharp changes in their area or external pressure. These phenomena create discontinuities due to a sudden jump on mechanical properties, which is a challenge when trying to simulate unsteady blood flow circulation. This work compares numerical methods to face this challenge in the context of a finite volume model.
