Receptivity characteristics of under-expanded supersonic impinging jets

The receptivity of an under-expanded supersonic impinging jet flow at a sharp nozzle lip to acoustic impulse disturbances is investigated as a function of geometric and flow parameters.

本研究针对尖锐喷嘴唇缘（sharp nozzle lip）处的欠膨胀超音速冲击射流（under-expanded supersonic impinging jet）流场，探究其对声脉冲扰动（acoustic impulse disturbances）的接收特性随几何参数与流动参数的变化规律。
