Evolution of Unmagnetized and Magnetized Shear Layers
Evolution of Unmagnetized and Magnetized Shear Layers
We present numerical simulations of the growth and saturation of the Kelvin-Helmholtz instability in a compressible fluid layer with and without a weak magnetic field. In the absence of a magnetic field, the instability generates a single eddy which flattens the velocity profile, stabilizing it against further perturbations. Adding a …
