【Abstract】 Based on CFD related theory, the feasibility of the single-phase flow cavitation flow is analyzed. The geometric model for numerical simulation is built. A standard orifice plate model is used to study the reliability of the single-phase flow FloEFD. The flow characteristic of V-shaped orifice regulating ball valve is analyzed. Several groups of orifice regulating ball valve structure are designed. The optimal design scheme is put forward to realize accurate control flow.更多还原
