Shocks and discontinuities (magnetohydrodynamics) - Wikipedia
In magnetohydrodynamics (MHD), shocks and discontinuities are transition layers where properties of a plasma change from one equilibrium state to another. The relation between the plasma properties on both sides of a shock or a discontinuity can be obtained from the conservative form of the MHD equations, assuming conservation of mass, momentum ...
MHD Shocks and Discontinuities Nick Murphy Harvard-Smithsonian Center for Astrophysics Astronomy 253: Plasma Astrophysics February 22, 2016 These lecture notes are based o of §5.6 of The Physics of Plasmas by Boyd and Sanderson; Chapter 5 of Magnetohydrodynamics of the Sun by Priest; §4.5 of Goedbloed & Poedts; Chapter 20 of Goedbloed,
Magnetohydrodynamics Unit 9 – MHD Shocks and Discontinuities
MHD shocks and discontinuities are essential for understanding the dynamics of magnetized plasmas in space and astrophysical environments; Shocks can form due to supersonic flows, such as in the solar wind, or due to the collision of magnetized plasmas, such as in magnetic reconnection events
6.2 SHOCKS = discontinuities across which there is a flux of mass; they are created when the plasma is moving with a speed higher than the information can propagate and encounters an obstacle. All MHD shocks have the property of coplanarity = downstream magnetic field lies in the plane defined by the upstream magnetic field and the shock normal
Chapter 6 Magnetohydrodynamic Shocks - ScienceDirect
This chapter describes the magnetohydrodynamic shocks. According to the general theory of shocks, magnetohydrodynamic solutions involve discontinuities such as shocks are governed by the conservation laws.

Discontinuities and Shocks (Chapter 6) - Introduction to Modern ...
2016年10月13日 · Behind this shock, there is a turbulent area called the magnetosheath which serves as a transition to the magnetosphere that is reached by crossing a discontinuity called the magnetopause. There is another type of interface for the solar wind: the terminal shock at the edge of the solar system (~100AU) when the wind speed becomes subsonic.

Stability of Strong Discontinuities in Fluids and MHD
2002年1月1日 · This chapter is devoted to the issue of stability of strong discontinuities in fluids and magnetohydrodynamics (MHD) and surveys main known results in this field. All the main points in the stability analysis are demonstrated on the example of shock waves in ideal models of gas dynamics, relativistic gas dynamics, and MHD.
