Explosion Driven Magnetogasdynamic Flows with High Magnetic Reynolds and Interaction Numbers

摘要

Detonation driven magnetogasdynamic generators with external R-L load circuits are analyzed, for which the external and induced magnetic fields are parallel and antiparallel, respectively. Two plasma shock flow models are treated: (i) implosion produced jet flow and (ii) plane detonation flow. - A theory of power generation is developed for a stress polarizable solid between plane electrodes (with an external ohmic load circuit), which is electrically polarized by an explosion produced stress shock wave. - In connection with the analysis of flux compression power generators, initial-boundary-value problems for the diffusion of magnetic fields into conductors with external electromagnetic transients and the electromagnetic induction in conductors accelerated in external magnetic fields are solved. - A quantum-kinetic theory of the anomalous electron heating in plasmas by high-frequency electromagnetic fields is presented.
