| 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. This work was supported by DoE and a joint U.S-Czech grant. These results were presented at the 6th International Workshop on Plasma Edge Theory in Fusion Devices, 15–17 September 1997. |
