Simulation of Rotation Left Ventricle Assistant Device

Abstract

Left ventricular remodeling is a process of progressive alteration of ventricular size, shape and function. A left ventricular assist device (LVAD) receives blood from the left ventricle and delivers it to the aorta. The HVAD is a small continuous-flow rotary pump which working as third generationwhich is simulationits work in this project. Computational modeling is the first step to simulation work of HVAD by using solid work program after this step must be tested the device to ensure if the device provide 5L/min so to reach this flow, the velocity is adjusted until achieved the flow in 50000RPM. Also the parameter (pressure and temperature) are tested to ensure the device is safe to human. The final step after testing the device is manufacturing it. There are three options to manufacture, but the option which we found is turn machine. The result in computational is acceptable but result after manufacturing is not acceptable (not provide 5L/min) due to the change occurring in the dimensions of devise.
