摘要
本文通过数值模拟的方法,探讨的两个同向旋转的涡,所产生的声场分布特性,结果表明,两个旋转的涡表现出四极子特性;涡心处的声压随马赫数的增加而增加;随涡间距的改变,涡心处的声压呈现正负交替变化的特性。
In this paper, the distribution of the acoustic field on the two co-rotating vortices by numerical simulation method. The results show that the two co-rotating vortices have quadrupole characteristics; The acoustic pressure in centre of vortex increases with the increase of Mach number; The acoustic pressure in centre of vortex presents the characteristics of positive and negative changes with increase of vortex spacing.
