Hall Effects in Linearized Magnetogasdynamic Flows

Abstract

Hall effect in a steady flow of a conducting gas past a thin wedge section in a strong aligned magnetic field is considered within the linearized theory. The flow field around the obstacle is found by the numerical integration of the Fourier transform. The outer flow is estimated by the method of asymptotic expansions. It is shown that the Hall effect leads to a dispersive field, which differs variously in association with the conductivity and compressibility of the flow, and that it tends to revive the ordinary gasdynamic aspects.
