Title
An Overset Mesh Approach for Valve Closure: An LVAD Application.
Abstract
A comprehensive Computational Fluid Dynamics (CFD) simulation of transient, non-Newtonian, and turbulent blood flow through a positive displacement pump, left ventricular assist device (LVAD), is executed. Non-Newtonian blood flow is conducted to investigate the flow through a pulsatile pump LVAD by using common blood viscosity model: Carreau. The numerical results of non-Newtonian fluid with a turbulence model, Elliptic Blending Reynolds Stress Model (EB-RSM) are presented. The computational domain that has been selected is a pulsatile pump, which includes valves and a moving pusher plate. An overset mesh zero gap technique was employed to capture the cyclic motion of pusher plate and valves rotation to mimic the scenario of a natural heart. The use of this technique to rotate the valves and ensure full valve closure presented a good agreement results with the experimental data.
