A meshfree arbitrary Lagrangian-Eulerian method for the BGK model of the Boltzmann equation with moving boundaries
Sudarshan Tiwari, Axel Klar, Giovanni Russo
In this paper we present a novel technique for the simulation of moving boundaries and moving rigid bodies immersed in a rarefied gas using an Eulerian-Lagrangian formulation based…
Modeling and simulations of moving droplet in a Rarefied gas
S. Tiwari, A. Klar, G. Russo
We study a two phase flow with interactions of liquid and rarefied gas inside the gas phase. The gas phase is modeled by the BGK model of the Boltzmann equation. The liquid phase i…
Relaxation models for scalar traffic networks and zero relaxation limit
Raul Borsche, Axel Klar
In this paper we propose coupling conditions for a relaxation model for vehicular traffic on networks. We present a matched asymptotic expansion procedure to derive a LWR- network…
Disease contagion models coupled to crowd motion and mesh-free simulation
Parveena Samim Abdul Salam, Wolfgang Bock, Axel Klar +1
Modeling and simulation of disease spreading in pedestrian crowds has been recently become a topic of increasing relevance. In this paper, we consider the influence of the crowd mo…
