多路换向阀流道的优化计算方法──代数应力模型

A new method of digital simulation for flow path in multiple directional control valve Al gebraic stress model (ASM)

本文根据Ｎａｉｖｅｒ－Ｓｔｏｋｅｓ方程推导一种比传统数学方法更优越的代数应力模型。这种模型除了能计算出传统的速度和压力外，它还能计算出紊动能和素动耗散率等。这是研究液压阀流道的一种很有效的数值方法。

This paper derives a superior alge braic-stressmodel to traditional mathematical method according to Navier-Stokes equation. The model can calculate turbulent energy and turbulentdissipation rating besides traditional velocityand pressure. It is a very valid simulation method for studying the hydraulic valves flow path
