In our previous study, it has been found that installing an axi-asymmetrical baffle plate upstream of cavitating inducer is
very effective for the suppression of cavitation surge in two-bladed flat plate helical inducer. In the present study, to obtain
the design guideline of this suppression device, it was applied for the suppressions of cavitation surge and rotating cavitation
in a three-bladed inducer. It was confirmed that the cavitaion surge could be well suppressed by this device, especially
when installed at about 55% tip diameter upstream of inducer leading edge; this location is similar to that for the effective
suppression in two-bladed inducer. Rotating cavitation could be also weakened by this device, but the effect was very limited.
Many of serious left ventricle failure patients suffer from right ventricle disease, therefore, right ventricle assist blood
pump is necessary for bridge to transplantation. Moreover, the designing of the right ventricular assist centrifugal blood
pump by conventional pump design method is difficult, as the specific speed is low, as well as the left ventricular assist centrifugal
blood pump. In the present study, the shape of the right ventricular assist centrifugal blood pump, which has gradual
pressure drop characteristic within the range of adult blood flow rate, was investigated by the CFD analysis. As a result, it
was found that suitable pressure for assisting the right ventricular by adopting appropriate volute and vane shape is
obtained, and the maximum pump efficiency is about 45%, which doesn't increase even if various vane shapes are changed.
