Dynamic characteristics analysis of the r eactor coolant pum p variationb ased on fluid-structure coupling
摘要
Abstract
In this paper, a study of the blade deformation caused by cavitation and the change law of radial force when cavitation occurred in the reactor coolant pump is presented.On the basis of considering the fluid-structure coupling, the impeller maximum deformation and radial force of the reactor coolant pump under different cavitation conditions were simulated numerically.The results showed that the maximum gas volume fraction corresponds to the maximum deformation of the vane inlet in the region of cavitation occurred.The maximum deformation of the impel-ler is mainly affected by the pressure pulsation in the initial cavitation.When the cavitation develops, the cavitation only has influence on the impeller's maximum deformation amplitude.The fluctuation amplitude is still dominated by the pressure pulsation and the cavitation only impacts the radial force position and fluctuation amplitude.Cavita-tion is a main factor of the impeller's maximum deformation fluctuation amplitude under the serious cavitation condi-tion.Under this condition, the cavitation not only has effect on the radial force position and the fluctuation ampli-tude, but also is a significant impact on the value of the radial force, so in the following design the focus needs to be put on considering effects of cavitation on the radial force.关键词
