-
摘要: 本文讨论了轴对称阻塞喷注中的湍流混合噪声源的分布。分析表明,在阻塞喷注中,声源的分布十分复杂。
同时,本文讨论了阻塞喷注中湍流噪声与压力的关系;定量地分析了阻塞喷注中压力梯度对源强度和湍流噪声的影响。Abstract: In this paper, the distribution of mixing turbulent noise source in a choked jet was studied. It was noticed that this distribution is very complex.
The relationship between turbulent noise and pressure in the choked jet was obtained. The effect of pressure gradient was also discussed in this formula.
