Eulerian simulations of parallel transport in the SOL

We continue to investigate kinetic models for simulating the heat load on the divertor plates during transient events as edge-localised modes (ELMs). Our previous work [36] deals with Vlasov-Poisson equations for two particle species for the dynamics of their transport parallel to the magnetic field. We started to improve this model by adding an equation for the evolution in time of the perpendicular temperatures. These equations take also into account the collisions between species which may play a role over long times. The first numerical results are encouraging, showing different features with respect to the older (simpler) model when computing total particles and energy fluxes on the divertor plates.
