Some Remarks on the Magnetogasdynamic Linearized Theory

Abstract

The general theory of magnetogasdynamic linearized flow is extended to cover the case of unsteady flow in an arbitrary direction with respect to the magnetic field. This theory is also valid in the case when the frame is “body axes” slightly inclined against the free stream direction. For the case of steady flow, quadratic expression for the pressure disturbance is derived. Some problems when weak electromagnetic interaction exists are solved for illustration of the application.
