Research on Flow Characteristics of Throttle Valve Based on Fluent

Abstract In order to improve the design of the throttle, a certain throttle is taken as the research object, and its flow coefficient is studied. Investigate the flow line characteristics of the throttle valve flow channel and the value of the flow coefficient of the throttle valve, use Fluent fluid software to perform numerical simulation analysis on the throttle valve flow channel, study the relationship between the throttle opening and the switching stroke, and simulate Calculation results The chamfer design of the throttle valve has a great influence on the initial section of the flow coefficient curve, and the opening range of the valve that can accurately control the flow rate is obtained.
