摘要
采用CFD方法对一种锥形阀口滑阀内流场进行了数值仿真计算,分析了在固定条件下其阀口处流场分布情况,并从阀口开度及结构参数等方面对影响阀口处流场分布进行了分析比较。研究结果表明:其阀口处流体流动情况复杂,流场在其轴向及径向分布不均衡,受阀口开度及结构参数等方面的影响;可通过优化阀口结构参数,改变阀口开度来改善阀口处流场分布状况,抑制气穴及旋涡的产生与发展,减小压降及能耗。
The numerical simulation computation of flow field in a conical spool valve was carried,which was based on CFD approach. The simulation results of flow field distribution under fixed condition were analyzed,and the influence of opening and structural parameters of valve port on the flow field distribution in valve port were also analyzed and compared. The results show that the fluid flows complicatedly in valve port ,the flow field distribution is uneven in the axial and radial and affected by the opening and structural parameters of valve port; optimizing the structural parameters of valve port and changing the valve opening can improve the flow field distribution in valve port, prevent the cavitation and the vortex forming and developing, reduce pressure loss and energy consumption.
