Abstract：The high fuel temperature rise at the shut-off operating condition in a reheat fuel centrifugal pump is addressed by cooling the impeller by fuel flowing through a by-pass from the pump inlet. The ejection-cooling is analyzed using the Reynolds average Navier-Strokes (RANS) method with the shear stress transport (SST) turbulence model and the Rayleigh-Plesset cavitation model. The results show that the ejection-cooling design can reduce the high fuel temperature rise at the shut-off condition. The power consumption and the friction heat are both reduced in the reheat fuel centrifugal pump with the ejection-cooling device because of the vapor core region in the impeller central zone which reduces the fuel temperature rise.
