Numerical simulations combining solid and fluid models and fluid-structure interaction
effects were performed for a diaphragm-type ventricular assist device (VAD). These …

A numerical simulation of the fluid and structure interactions was performed for a diaphragm-
type ventricular assist device (VAD). The simulation was included two incompressible fluids …

This work extends previous open-loop simulations of an idealized, diaphragm-type
ventricular assist device by coupling it in a closed loop to a three-dimensional model of the …

A ventricular assist device (VAD) is a pump surgically connected to the heart and aorta in
order to boost systemic blood flow in heart failure patients. The design of these devices has …
