On description of periodic magnetosonic perturbations in a quasi-isentropic plasma with mechanical and thermal losses and electrical resistivity
Abstract
Magnetosonic periodic perturbations in a uniform and infinite plasma model are considered. Damping due to compressional viscosity, electrical resistivity, and thermal conduction are taken into account, as well as some heating–cooling function, which may destroy the isentropicity of wave perturbations. The wave vector forms arbitrary angle h with the equilibrium straight magnetic field, and all perturbations are functions of time and longitudinal coordinate. Variable h and plasma- b bring essential difficulties in the description of magnetosonic perturbations, which may be fast or slow. Wave damping of each kind depends differently on h and plasma- b . Longitudinal velocity, which is periodic at any distance from an exciter, is analytically constructed. It approximates the exact solution with satisfactory accuracy.
