Аннотация: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 Alfven 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.
