Determination of the parameters of motion of a fluid during the diffraction of a powerful magnetogasdynamic shock wave at an angle approaching a straight angle
Abstract
A nonstationary, three-dimensional problem is presented, which examines the motion of an electrically conducting compressible fluid in a magnetic field in the presence of the diffraction of a strong magnetogasdynamic shock wave at a wall whose sides form an angle approaching a straight angle. Analytical relations are found for the parameters of motion behind the shock wave of a constant intensity. The Smirnov-Sobolev method is used to obtain the boundary value problem for determining the analytical functions; the problem is solved by the Lighthill method. The resulting linear-solution singularity for a fast magnetoacoustic wave is eliminated. A linear solution is also carried out in the vicinity of a singular point of a slow magnetoacoustic wave.
