Abstract

Computational and experimental studies on a forward-sweep inducer for turbopumps were performed to see the effect of the blade sweep on the suction performance of the inducer. Computational results show that backflows at the inlet decrease in the case of the forward-sweep inducer by inhibiting pre-rotation of the inflow and the low pressure region near the tip also diminishes, which is presumed to improve the suction performance of the inducer. The predicted suction performance of the inducer is compared with the experimental result. The result shows that the computation overestimates the suction performance of the inducer compared to the value from the experiment.
