失水事故初期核主泵气液两相流动特性
Gas-liquid two-phase flow characteristics of the nuclear main pump during the initial localized constructed analogs condition period
摘要
Abstract
The gas-liquid two-phase flow in a nuclear main pump during the initial stage of localized constructed an-alogs (LOCA) condition was investigated through simulative calculation with ANSYS CFX.Several aspects of the nuclear main pump were investigated, such as the outer properties of the nuclear main pump and the distribution of the gas phase.The analytical results indicate that the efficiency of nuclear main pump, the axial torque, and the change of delivery lift follow a proper law.In addition, gas phase aggregation is characteristic.The influencing fac-tors mainly include the physical properties of gas, the instability of the flow field in the pump, and rotor-stator in-teraction.The degree of pressure fluctuation in the flowpassage of the vane is related to the distance between the lo-cation and the stator-rotor interface, and the degree of pressure fluctuation in the guide vane is more intense than that in the impeller.The radial force exerted on the impeller has many maximum values throughout one impeller ro-tation cycle.Following the continuation of accident, these maximums tend to be equal.关键词
