Abstract：For the horizontal-baffle type surge tank of the water flow standard facility, a computational fluid dynamic model was established on the basis of the Navier-Stokes equations. The numerical simulation of the two-phase flow field characteristics in the surge tank was achieved through the turbulence model and volume of fluid transient model, by applying the finite volume method for performing discretization, and standard wall function for modification in the near-wall region. The calculated results showed that, the water flow in the empty tank passes through the following states: anhydrous state, jet flow, upper backwater, overflow and steady state. Meanwhile, aerated flow and bubble flow were formed. In the case of gas-liquid ratio 13, there was a phenomenon of water sloshing in the flow filed of the tank with fixed period, and a vortex gas chamber was formed in the upper side which rotates counter clockwise. The flow field was characterized by lower turbulent viscosity, relatively uniform distribution and best stable performance.
