Abstract

In the divertor plasma detachment regime one expects to encounter turbulent collisional neutral gas dynamics. These conditions are ideally simulated by lattice Boltzmann methods — methods ideal for application on multi-parallel processors. As illustrative of this method, we specifically show the effect of conductivity in the Rayleigh-Benard convection cells, using an octagonal velocity lattice.
