基于空化模型的多级离心泵汽蚀性能分析
Analysis on Cavitation Performance in Multi-stage Centrifugal Pump Based on Cavitation Model
摘要
Abstract
A cavitation analysis model for centrifugal pump is developed based on the Rayleigh-Plesset bubble equation.The 3D turbulent flow field and gas-liquid phase distribution in a multi-stage centrifugal pump are computed by solving the bubble equation coupled with two-phase turbulent governing equations.The process of bubble vaporization, growing and condensation are simulated and visualized.The cavitation model and simulation are validated by comparing numerical solutions with tested curve of Q-NPSHr for the pump.关键词
