A Partial Entropic Lattice Boltzmann MHD Simulation of the Orszag-Tang Vortex

摘要

Karlin has introduced an analytically-determined entropic lattice Boltzmannalgorithm for Navier-Stokes turbulence. Here this is partially extended to alattice Boltzmann model of magnetohydrodynamics, on using the vectordistribution function approach of Dellar for the magnetic field. (which ispermitted to have field reversal). The partial entropic algorithm isbenchmarked successfully against standard simulations of the Orszag-Tang vortex(1979).
