Abstract

Two dimensional flow field in the jet pump was computed by FLUENT software based on the body-fitted coordinate system. The compute model was divided into 10090 computing elements by GAMBIT software. Finite element method and k-ε double equation were used in the calculation. Boundary condition of pressure import and pressure export was calculated by SIMPLE method. It indicated that the flow field would emerge turbulence when the area ratio of cavitating flow was 10.9 in the jet pump. Strong vibration and high noise would generate when it appearing two-phase flow cavitation from outlet to end of the throat pipe. It provided a brief theoretical basis for researching and designing of jet pump.
