Using one way fluid structure interaction coupling to investigate the effect of blood flow on the bileaflet mechanical heart valve structure

A numerical simulation investigation was conducted to investigate the effect of vibration on the structure of bileaflet mechanical heart valve by using one way Fluid Structure Interaction coupling technique. The forces generated due to blood flow and heart pulsation which consequently cause vibratio...
