WebThe formation of the shock wave in front of the magnetopause is more complicated than the simple airplane analogy. For one thing, the magnetic field imbedded in the solar wind is intimately associated with establishing the detailed characteristics of the shock. Furthermore, the shock wave is a collisionless shock; that is, the solar wind ... WebIn this Letter, the dynamics of a collapsing vapor bubble is addressed by means of a diffuse-interface formulation. The model cleanly captures, through a unified approach, all the critical features of the process, such as phase change, transition to supercritical conditions, thermal conduction, compressibility effects, and shock wave formation and propagation.

WebThus, the shock wave formation process can be reasonably described without considering the re-absorption of radiation power inside the plasma volume. It is also revealed that even though the current rise rate is much increased, the energy transfer efficiency to the hydraulic motion becomes significantly degraded by the rapidly increasing ... In physics, a shock wave (also spelled shockwave), or shock, is a type of propagating disturbance that moves faster than the local speed of sound in the medium.
