Publisher's Synopsis
Excerpt from Diffraction of a Hydromagnetic Wave by a Half Plane
In this paper we solve for the diffracted wave which results when a weak hydromagnetic shock impinges on a rigid perfectly conducting half plane. We assume a medium which is a compressible perfect fluid (no heat conduction, no viscosity) and a perfect electrical conductor. In the undisturbed state the fluid is at rest and is permeated by a constant magnetic field B6. The fluid extends through all space around an obstacle, in the shape of a half plane, made of a rigid perfectly conducting material. Then, possibly due to a distant disturbance, a weak plane discontinuous wave or weak shock propagates through the fluid. We are interested in the diffracted wave caused by the interference of the half plane obstacle after the incident wave arrives. We assume that the amplitude of the disturbance of the fluid is small, so that it is appropriate to employ the linearized equations of motion.
