Fluid equations governing the dynamics and energetics of partially ionized dusty magnetoplasmas

A set of nonlinear equations for multi-component partially ionized dusty magnetoplasmas is developed, taking into account the contributions of frictional thermalization, collisional heating in the energy equations on one hand, and those of ionization and recombination in the continuity equations on the other hand. The present nonlinear equations form a tool for numerical simulation studies of various collective effects in the presence of sources and sinks. However, in order to illustrate possible applications of the present system of equations, two examples of thermal condensation instabilities are discussed. (C) 1997 American Institute of Physics.
