Taking equal-pitch inducer as research object, using cavitation and mixed two-phase flow model, this article applied transient state numerical simulation to the whole passage on front-loading inducer of Y2-315M-2 centrifugal pump with CFD software.Based on calculation result,the distribution of static pressure and the flow feature both of liquid phase and cavity phase on blade were analyzed. The simulated results showed that the inducer had good anti-cavitation performance by itself.
