Large-Eddy Simulation of a Shear-Free Magnetohydrodynamic Mixing Layer

Abstract

We present LES results of the evolution of a decaying magneto hydrodynamic (MHD) mixing layer using dynamic eddy-viscosity subgrid scale models. The LES results are obtained using a spectral code with a 32(exp 3) resolution and are compared to a direct numerical simulation (DNS) with 128(exp 3) Fourier modes. The evolution of the kinetic and magnetic energies is presented and their profiles along the inhomogeneous direction is also discussed.
