Large eddy simulations of inhomogeneous high-magnetic Reynolds number magnetohydrodynamic flows

Large eddy simulations of high-magnetic Reynolds number (Rem) inhomogeneous magnetohydrodynamic (MHD) flows are performed. Dynamic Smagorinsky sub-grid scale model is used for closure. A hybrid formulation spectral and finite difference methods developed to carry out the simulations. The current code validated by comparing it previously published benchmark channel flow results. carried at a bulk 2200 unity magnetic Prandtl increasing values interaction parameters. This paper aims explore effect velocity shear on initially band or striae-type structure field, using MHD Rem low (0.0088) high (0.5) parameters (N). analyzed plotting mean quantity variations with time in direction, spectra (a) kinetic energy; (b) transfer energy from large small scales; (c) between field. It observed that higher parameter, transition laminar turbulent inhibited, while lower value, state observed. final N= 0.0088 characterized homogeneous distribution scales formed due breakdown initial striae structures as seen x-direction iso-surface plots density, second invariant gradient tensor.
