Effect of Horizontal and Vertical Magnetic Fields on Kelvin?Helmholtz Instability

Abstract

This paper discusses the effect of a general oblique magnetic field on the stability of two superposed fluids in relative horizontal motion. The stable and unstable cases at the interface (z = 0) between two uniform fluids with constant denRities and velocities of streaming are separately discussed. The combined effect of horizontal and vertical magnetic fields is to increase the wavelength at which the Kelvin-Helmholtz instability sets in.
