Hydromagnetic Stability of Free Flows at Large Reynolds Numbers. IV. Free Two-Dimensional Jet

Abstract

The effects of an aligned uniform magnetic field upon the stability of a two-dimensional jet of an incompressible, electrically conducting fluid with small magnetic Prandtl number are investigated for flows of large Reynolds number. The condition for stability is obtained as a relation between the wave number, the Reynolds number, and the Alfvén number for small magnetic Prandtl number.
