Asymptotic preserving schemes for magnetic confinement
Friday, April 27, 2PM – 3PM
One of the main topics in plasma physics concerns the energy production through thermonuclear fusion, which is achieved by magnetic confinement. From the mathematical point of view, the transport of charged particles under strong magnetic fields reduces to multiscale analysis. This paper deals with numerical schemes, based on macro-micro decomposition of the particle distribution function, which are uniformly consistent with the pde models for any order of the magnetic field. Numerical simulations, based on this approach, are presented for the resolution of the Vlasov equation.
