Math/ICES Center of Numerical Analysis Seminar: Multi-species kinetic and fluid models and applications by Christian Klingenberg (Wuerzburg University, Germany) in POB 6.304
We consider a multi component gas mixture. This mixture is modelled by a system of kinetic BGK equations. Consistency of the model is proven, also existence, uniqueness and the positivity of solutions. We can extend our model to an ES-BGK model and to polyatomic mixtures. By taking moments, this allows us to derive macroscopic two-species conservation laws. We present numerical simulations using an adaptive kinetic-fluid models for plasma simulations. This is joint work with Marlies Pirner (Wuerzburg University, Germany) and Gabriella Puppo (Universita Insubria, Italy). Submitted by
