XFEM FSI simulations of new cardiac pumps

In the context of the European Project “ROMSOC – Reduced Order Modelling, Simulation and Optimization of Coupled systems’‘ (H2020-MSCA-ITN-2017, EU project 765374), a new family of cardiac pumps based on membrane waves oscillations which allow to win the adverse pressure gradient has been studied.
With respect to standard rotatory pumps, these new pumps reduce the stagnation and recirculation regions which are prone to formation of thrombi.
This project has been developed in collaboration with Corwave, a company based in Paris that proposed this new family of pumps. From the mathematical point of view, the problem is a fluid-structure interaction, with immersed structures handled by means of the XFEM strategy.
