气动发声的数值计算

Numerical Simulation of the Aeroacoustic Generator

为研制一种低频高声强的气动发声器,对气动发声过程在理论分析的基础上,利用流体动力学计算和声学分析结合软件进行了系统地仿真和计算,得出了气动发声系统的匹配参数的影响规律,为气动发声系统设计研究提供参考依据。

In order to develop the aeroacoustic generator of the high sound intensity of a kind of low frequency, on the basis of the thing that the theory is analyzed to the course of sounding pneumatically, we utilize hydrokinetics to calculate to analyze with acoustics that the software of combining has carried on the systematic ground emulation and calculation, draw aeroacoustic to sound match influence law of parameter of system, for being aeroacoustic to sound system is it is it offer reference basis to study to design.
