Lattice Boltzmann formulation for Braginskii magnetohydrodynamics

摘要: Braginskii magnetohydrodynamics is a single-fluid description of large-scale motions in strongly magnetised plasma, one which the ion gyroradius much smaller than mean free path between collisions an unmagnetised plasma same density and temperature. The relation stress strain rate then becomes highly anisotropic, with viscous being predominantly aligned parallel to magnetic field lines. We modify existing lattice Boltzmann formulation isotropic resistive simulate by introducing anisotropic collision operator for hydrodynamic distribution functions. This applies different relaxation time component directed field. method illustrated comparison independent numerical solutions steady planar channel flows.
