Monte Carlo-PIC simulation of plasma flows with space applications

摘要

Summary form only given, as follows. Particle simulations of spaceplasma flows are presented. The first case involves the simulation of apartially ionized hydrogen plume. The direct simulation Monte Carlomethod is used for the neutral flow component and a PIC basedmethodology is used for the ionized component. The second case involvesthe PIC-MC simulation of a fully ionized flowing plasma that includeslarge dust particles. Collisions of plasma species with the dustparticles are modeled via a Monte Carlo operator. The simulation resultsare compared to analytic solutions. Differences in the computationalstrategies involved in these two cases are discussed
