Weak disturbances of magnetogasdynamics discontinuities
Technical Report
·
OSTI ID:7221540
The influence of weak disturbances on magnetogasdynamic discontinuities was investigated. In particular, the important case of magnetogasdynamic shock waves was studied. After linearization of the magnetogasdynamic differential equations, the flow fields before and behind the discontinuity were matched by means of the linearized Rankine--Hugoniot relations. By specialization of these general equations the different cases up to the one-dimensional gasdynamic shock waves are obtained. As an example the disturbances for gasdynamic shock waves were calculated. A disturbance in front of the shock wave generates entropy when crossing the shock wave.
