湍流、明渠流动的动态粗糙表面对空气中声音的散射问题知之甚少。本文利用激光诱导荧光(LIF)技术，对雷诺数为10,800的矩形水槽中6个亚临界湍流的动态粗糙表面的瞬时高程进行了精确的测量
The problem of scattering of airborne sound by a dynamically rough surface of a turbulent, open channel flow is poorly understood. In this work, a laser-induced fluorescence (LIF) technique is used to capture accurately a representative number of the instantaneous elevations of the dynamically rough surface of 6 turbulent, subcritical flows in a rectangular flume with Reynolds numbers of 10,800
