Magnetogasdynamic Phenomena in Pulsed MHD Flows.

Abstract

This work is aimed at the understanding, description, and prediction of magnetohydrodynamic phenomena exhibited under conditions of extremely high interaction and large magnetic Reynolds number. The plasmas which constitute the fluid medium in such flows may exhibit nonideal thermodynamic and kinetic behavior. The theoretical work has two principal objectives: the elucidation of basic phenomena in strong interaction high magnetic Reynolds number flows independently of specific experiments or machines, and the perfection of predictive theories to accurately describe and model specific experiments aimed at magnetohydrodynamic power production. In what follows we present the general mathematical description of magnetogasdynamic flows in the high magnetic Reynolds number regime. We present several illustrative calculations of quasi-one-dimensional transient effects in strong interaction flows. Two-dimensional high Reynolds number electricity results are presented including the realistic effects of nonuniform velocity and electrical conductivity resulting from hypersonic boundary layers and from shock-induced nonuniformities.
