摘要
本文研制了一种启闭频率高达10Hz的气动发声阀门。利用了流体动力学数值仿真软件(FLU ENT)对其内部流场先进行数值仿真,并通过改变均衡进气孔参数,优化了阀门内部流场分布情况。
The pneumatic Valve of a high intensity sound generator whose open frequency is 10Hz is developed. Numerical simulation of the inner flow field of the pneumatic valve is carried out using FLUENT software. Distribution of the inner flow field of the pneumatic valve is optimized by adjusting parameters of the inlet.
