Abstract

The features of the non-plane-polarized interaction of two plane MHD shock waves colliding at an arbitrary nonzero angle in the presence of an arbitrary magnetic field are considered. The problem is solved over a wide range of key parameters. When the key parameters of the problem vary continuously, there are no sudden restructurings (catastropies) of the flow pattern characteristic of the plane-polarized case. As distinct from the plane-polarized case, in the flow developed always there are two Alfvén discontinuities of different intensities with circular polarization. The presence of a magnetic field along the line of intersection of the shock fronts smoothers variation of pressure on the contact discontinuity C as a function of the angles of inclination of the magnetic field, the pressure on C being less than that in the plane-polarized case by several times. The velocity acquired by the medium as a result of the interaction depends significantly on the inclination of the magnetic field.
