Abstract: This paper shows a first version of a new geometrical and computational model of a Ventricular Assist Device (VAD). The main aim and purpose of this model is to serve as a computational test case and benchmark for mutual cross-comparison of numerical simulations employing different grids, solvers, and additional mathematical model extensions. The simplified VAD was designed as a fully parametric adjustable geometry, allowing for easy change of the essential model shape parameters to assess their effect on the VAD’s performance. The description of the newly developed VAD geometry is presented, briefly describing its structure and main shape parameters. The first numerical simulations of the flow in the resulting VAD model are presented, based on the OpenFOAM finite-volume solver implemented in the TCAE Engineering Simulation Environment. The presented first numerical results show the applicability of the newly developed VAD’s model geometry for computational fluid dynamics (CFD) evaluation and benchmarking.
