Abstract

2D numerical simulations of some control valve were carried out based on RANS method by using FLUENT 6.3 software. The finite volume method, standard k-ε turbulence model and SIMPLE algorithm were applied in the calculations, the main factors of cavitaving flow in control valve was found out. According to the principle of throttle step-down, mutations in a high pressure drop to the pressure gradient over small with multi-level throttle step-down control measures. The feasibility of the principle of throttle step-down in cavitational noise was proved by using CFD software, which provide a reliable basis for theoretical study and optimal design of control valve.
