本文针对滑阀阀道内的流体流动，采用湍流模型的K─ε两方程模型和有限容积数值方法，对其进行了数值分析。同时计算了流动区域内各节点上的压力p，速度v，湍流脉动动能K和脉动能耗散率ε。通过计算，对于阀道内的流动有了一个初步的了解，为滑阀内部的结构设计及各几何参数的确定提供了一定的参考依据。 In this paper, for the flow of fluid in the valve spool, a K-ε two-equation turbulence model and a finite volume numerical method are used to analyze the numerical results. At the same time, the pressure p, velocity v, turbulent pulsating kinetic energy K and pulsatile energy dissipation rate ε on each node in the flow area are calculated. Through calculation, it has a preliminary understanding of the flow in the valve, which provides a reference for the structural design of the slide valve and the determination of the geometric parameters.
