Abstract：It describes the computational study of horizontal-baffle type surge tank of the water flow standard facility based on the standard k-ε turbulence model and volume of fluid multiphase transient model.The PISO algorithm is used to discrete the control equation, and the inlet velocity pulsation is defined by the UDF. The key information of the surge tank is obtained, such as pressure field, velocity field, stream trace and so on. The simulation reveals the influence of inlet pulse frequency, volume ratio of gas to water and position of the vertical baffle plate on the flow stability, and the computational result is verified by the experiment.The calculated results show low frequency pulsation has a bad influence on stability, when the inlet pulse frequency is 5Hz, the best volume ratio of gas to water is about 1:3, and the preferable position of the vertical baffle is at the front 1/3 of the surge tank.The flow fluctuation coefficient is 0.058% with the best stable performance.
