Modeling of ionized gas flows with a velocity-space hybrid boltzmann solver

Oblapenko, G.; Goldstein, D.; Varghese, P.; Moore, Christopher H.

A novel method based on combining Direct Simulation Monte Carlo (DSMC) and Discrete Velocity Method (DVM) representations of the velocity distribution functions in velocity space is applied to rarefied ionized gas flows in order to study its efficiency and accuracy. The objective is to improve the efficiency of modeling of flows where trace populations have a significant effect on the flow physics. Numerical results are obtained for a 0-dimensional flow of a Ar/Ar+ /e− mixture and compared with the BOLSIG+ solver.
