Abstract:  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. This is joint work with Marlies Pirner (Wurzburg University, Germany) and Gabriella Puppo (Universita Insubria, Italy).
