THE PROPAGATION OF THE ALFVEN WAVES IN THE FLOW AND THE MAGNETIC FIELD WITH AN ARBITRARY CONFIGURATIONS

This paper presents the propagation features of Alfven waves in the viscous and the thermal anisotropic plasma with an arbitrary flow and magnetic field configurations. The WKBapproximation is used for getting the tensor solution of the Alfven wave amplitude vector, which is a function of the density, velocity, magnetic field, Alfven speed, thermal ani-sotropy and viscosity. Some of simple cases are discussed and the result shows that the solution given by this paper is suitable for general cases and is convenient for studying three dimension propagation problems.
