Abstract

In this paper, for a certain type of horizontal single-stage single-suction centrifugal pump, a 3d model based on Pro/e is constructed and imported into Fluent, using moving reference frame model and two-phase mixture model to simulate the internal state of pump, then get the pressure distribution, vapor-liquid two-phase flow distribution, the vapor-phase volume fraction distribution within pump, when temperature remains constant and operating speed is changed by frequency control technology. Finally, compare and analyze these distributions. According to the main flow characteristics of the liquid-phase and the vapor-phase, reveals the intrinsic characteristics of cavitations in the two-phase flow field within pump. The results can provide a reference for the design optimization of centrifugal pumps and a theoretical basis to make the variable frequency regulation of pump get better and more rational application, and improve the effects of economic operation and energy conservation.
