Opis

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. Malfunctioning Mitral Valve and Aortic Valve will cause death if it not immediately detected. This book has been written to investigate the blood flow pattern for MV and AV in 3D view which developed by ADINA-FSI application. Both of valve models have been implemented without ventricles and presented as a newtonian fluid flow in steady condition. The simulation from this study will cover the blood flow pattern in term of velocity, effective stress on the leaflets, strain occurred in the critical area of both heart valves and the nodal pressure pattern flow during the steady condition. The findings shown, the velocity and nodal pressure are linear correlation with the blood pressure increased during systole process. The significant simulation results from this study were very useful to give a clear view to the medical practitioners about the pattern of blood flow.
