The multi-phase flow model in fluent is used to simulate and analyze the cavitation phenomenon of U + U-shaped combined throttle of multi-way valve core.The three-dimensional model of combined throttle with differ-ent length C,width R and depth B is established through SolidWorks.The three-dimensional model of throttle is ex-tracted in workbench,and the extracted channel model is simulated by fluent,Through the comparative analysis of 36 groups of data,the influence law of the depth,width and length of the large U-groove on the gas volume fraction at the throttle of the multi-way valve core is obtained.
