在下面的工作中，我们解决了一个平面声波的衍射问题的阻抗半平面在运动的流体。总远场的表达式推导出的前缘和后缘的情况。在后缘情况下，问题又增加了一个复杂的尾涡面或尾流。因此，施加Kutta-Joukowski边缘条件以确保流体速度在边缘处是有限的，并获得问题的唯一解。
In the following work we solve the problem of the diffraction of a plane sound wave by an impedance half-plane in a moving fluid. Expressions for the total far field are derived for both the leading edge and trailing edge situations. In the trailing edge situation the problem has the added complication of a trailing vortex sheet or wake. Hence a Kutta-Joukowski edge condition is imposed to ensure that the fluid velocity is finite at the edge and to obtain a unique solution to the problem.
