Hybrid Parallelization of Euler-Lagrange Simulations Based on MPI-3 Shared Memory
Patrick Kopper, Stephen Copplestone, Marcel Pfeiffer +3
The use of Euler-Lagrange methods on unstructured grids extends their application area to more versatile setups. However, the lack of a regular topology limits the scalability of d…
An ES-BGK model for diatomic gases with correct relaxation rates for internal energies
Julien Mathiaud, Luc Mieussens, Marcel Pfeiffer
We propose a new ES-BGK model for diatomic gases which allows for translational-rotational and translational-vibrational energy exchanges, as given by Landau-Teller and Jeans relax…
Exponential BGK Integrator for Multi-Scale Particle-Based Kinetic Simulations
Marcel Pfeiffer, Félix Garmirian, M. Hossein Gorji
Despite the development of an extensive toolbox of multi-scale rarefied flow simulators, such simulations remain challenging due to the significant disparity of collisional and mac…
