摘要：
The paper describes a simplified numerical analysis of turbulent flow field inside hydraulic conical valves using RNG k-epsilon turbulent model. The simulations are under unsteady, incompressible and cavitating conditions. The Reynolds numbers based on the uniform velocity and inlet diameter are 6.5x10(4) and 1.0x10(5). The fluid is water, and the structure of the flow passage in the valve is simplified as a two dimensional axisymmetric geometrical model. The velocity and pressure fields and the cavitation distribution are presented. The effects of flow rate, valve opening as well as cone shape on flow field are numerically investigated and compared.
