纯水液压球阀阀口流场的fluent仿真研究

Using the commercial CFD software - Fluent, based on the standard of hydraulic valves turbulence model, have a numerical simulation to the valve ports and the nearby cavitation flow field, then get the valve sewing place flow velocity and flow chart and pressures, the distribution of physical quantities, thus looking for possible cavitation zone, and its influence of the valve ports open degree, inlet velocity and outlet pressure. The study of pure water hydraulic valves cavitation has certain reference value to the generation and cavitation erosion control theory and application.
