Analyses of three shock interactions in magnetohydrodynamics: Alignedfield case
Abstract
The paper deals with the confluence of three shock waves at a point, in a magnetohydrodynamic (MHD) fluid. Based on the threeshock theory, the equations governing the flow field in the vicinity of the intersection point are obtained. The three shock confluences in fieldaligned cases are studied here using shock polars, revealing that only seven combinations of three shock types are possible. The relations among (a) the combinations of incident and reflected shock types, (b) the angle between incident and reflected shocks, and (c) the streamline deflection angle across the reflected shock are shown. As an example of application, the flow field induced by a supersonic MHD flow over a concave double wedge is studied both analytically and numerically. {copyright} {ital 1996 American Institute of Physics.}
