A spectral approach to interface layers on networks for the linearized BGK equation and its acoustic limit

Raul Borsche, Tobias Damm, Axel Klar +1

We consider in this paper a velocity discretized version of the full linear kinetic BGK model and the corresponding limit for small Knudsen number, the linearised Euler or acoustic…

A hierarchy of kinetic discrete-velocity models for traffic flow derived from a non-local Prigogine-Herman model

Raul Borsche, Axel Klar

Starting from a non-local version of the Prigogine-Herman traffic model, we derive a natural hierarchy of kinetic discrete velocity models for traffic flow consisting of systems of…

Implicit Active Flux methods for linear advection

Wasilij Barsukow, Raul Borsche

In this work we develop implicit Active Flux schemes for the scalar advection equation. At every cell interface we approximate the solution by a polynomial in time. This allows to…
