Multiscale Mathematics for Plasma Kinetics Spanning Multiple Collisionality Regimes.

摘要

The goal of this project is the development of accelerated simulation methods for plasma kinetics and the application of these methods to problems of interest for plasma fusion. Specifically, this project is developing methods for simulation of Coulomb collisions between charged particles. Collisional effects can be significant in the edge plasma of a fusion device, but correct simulation of the collisional effects is a computational bottleneck for current simulation methods. We developed two approaches to acceleration of simulation for Coulomb collisions. This is the Final Technical Report on this grant. The subject of this grant is accelerated simulation for plasma kinetics, in particular for Coulomb collisions in a plasma.
