摘要
用数值模拟研究了涡流阀的流量调节特性。在来流总压恒定的条件下，用时间相关法求解了雷诺平均的Ｎａｖｉｅｒ—Ｓｔｏｋｅｓ方程。计算了无控制流和有控制流两种情况，得到了流动参数在流场中的分布和控制流量与喷管流量的关系。计算表明，涡流阀有良好的流量调节特性。
The control properties of vortex valve for mass flow rate are numerically simulated. The time-dependent method is used to solve full Navier-Storkes governing equations. The calculation is made with the control mass added or not. The steady nozzle flowfield with vortex chamber is obtained and the nozzle mass flow rate is related withcontrol mass flow rate. The results indicate that the vortex valve has good property for controlling nozzle mass flow rate.
