Abstract
Experimental and computational studies on a turbopump inducer with and without a bearing strut were performed to evaluate the effects of a strut on the performance of an inducer. Head rise, efficiency and surface static pressures were measured and compared with computational results. Generally a good agreement is observed between experimental and computational results, but some discrepancies are observed due to complex flow features such as backflows at the inlet and strut/inducer interactions. For the flow rates where the backflow region is large, installing a strut enhanced the hydraulic performance of the inducer by diminishing the size of the backflows. The results also show that the strut has negligible effect on the suction performance of the inducer.
