摘要：
In this paper, the impact of flow and submerged depth of diversion canal on free surface vortex is studied by numerical simulation and experiment of water and gas two-phase flow. It can be seen from the calculation results that the lower the submerged depth or the higher the flow, the stronger the vortex intensity on the free surface. The strong vorticity and air content in water will lead to uneven flow in the elbow canal, affecting the stable operation of the circulating pump. According to the results of simulation and experiment, the numerical value of vortex type on the free surface is expressed as a function of flow rate and submerged depth. This function can be utilized to predict the submerged depth limit of diversion canals in coastal nuclear power plants, which provides a favorable guarantee for the stability of circulating pump operation and the economy of pump room construction.
