摘要:
本文对标准粘性边界法进行探讨.证明在平面波条件下只有波前法向垂直于边界时才是正确的,而在球面波条件下即使波前法向垂直于边界也不正确.本文提出了球面波条件下新的粘性边界法,计算结果亦表明,所提出的方法精度甚高.
Abstract:
It is proved that the standard viscous boundary is only correct when the normal of wavefront of the plane wave is perpendicular to the boundary. In the case of spherical wave eventhough the normal of wavefront is perpendicular to the boundary, this, method is incorrect.
A new viscous boundary under the condition of spherical wave is proposed. Numerical example illustrated that the new method is precise.
