Mhd shock
WebbFigure 1. A sketch illustrating the coplanarity theorem for a plane ideal MHD-shock. The upstream and downstream bulk velocities U 1 and U 2, magnetic fields B 1 and B 2 and the shock normal N all lie in the same plane. The shock is at rest in the reference frame where also u t1 = 0. The shock is of infinitesimal width in the sketch.

Shocks are transition layers across which there is a transport of particles. There are three types of shocks in MHD: slow-mode, intermediate and fast-mode shocks. Intermediate shocks are non-compressive (meaning that the plasma density does not change across the shock). A special case of the intermediate shock is referred to as a rotational discontinuity. They are isentropic. All thermodynamic quantities are continuous across the shock, …

As is well known, sound waves propagating ahead of the disturbance give … WebbIn MHD shocks, you obtain a new type of discontinuity: Rotational discontinuity: A rotation of the transversal magnetic field associated with the Alfven wave speed ~~~ This concludes the basic theory background. You can click on the Euler and MHD tabs on the top of the page to explore the shock structure in a interactive Mathematica module.
WebbOnly a very limited number of MHD slow shocks are observed within 1 AU. In order to understand why there are only a few MHD slow shocks observed within 1 AU, we use a one-dimensional, time-dependent MHD code with an adaptive grid to study the generation and evolution of interplanetary slow shocks (ISS) in the solar wind.
