Analysis of blood flow in 3d heart valve model under steady state condition

Mitral valve (MV) and Aortic valve (AV) are very important in circulatory blood inside the heart which function as a gate for the blood flow. Since the heart valves not working properly, the normal flow of blood inside the heart will be interrupeted. Malfunctioning Mitral Valve and Aortic Valve will...
