摘要：

The normal velocity field on arbitrary three dimensional scattering surfaces struck by a weak acoustic plane wave, is considered. A numerical solution for a right angle corner (i.e. three orthogonal edges of infinite length) is found for a step incident pressure wave, while the wavefront normal is taken to form equal angles with the three orthogonal edges. The scattering obstacle is assumed to have a free surface (i.e., pressure is zero). © 1969, Acoustical Society of America. All rights reserved.
