Abstract
Among the several aspects of numerical simulations, the boundary condition is one of the most important issues to deal with in simulations of the cardiovascular network. Previously we introduced a new method for modelling the downstream of the truncated artery by means of porous media theory. In the present work, we aim to investigate the reflection characteristics of this new model and find the relation between the permeability and the reflection ratio. Numerical simulations have been performed and seven different cases have been tested. The results show a strong dependence of reflection on the permeability magnitude and it was found that the porous interface behaves like an intermediate situation between closed-end and open-end tubes.
