Rambo, P W; Denavit, J

One dimensional multi-fluid simulations of interpenetrating plasmas are presented. Separate fluid equations for multiple species are solved with coupling between the different species due to the electric field and Coulomb collisions. These simulations show initial interpenetration followed by stagnation. We present scaling results for colliding plasmas characteristic of opposing, laser heated discs. Simulations of colliding CH plasmas with separate ion fluids for the Carbon and Hydrogen are presented showing appreciable atomic separation. We also show results from hybrid particle and fluid simulations, where particles are used in addition to fluids to represent physical species.
