Fokker-Planck-Poisson kinetics: Multi-phase flow beyond equilibrium
Mohsen Sadr, Marcel Pfeiffer, M. Hossein Gorji
Multi-phase phenomena remain at the heart of many challenging fluid dynamics problems. Molecular fluxes at the interface determine the fate of neighboring phases, yet their closure…
Multi-species modeling in the particle-based ellipsoidal statistical Bhatnagar-Gross-Krook method including internal degrees of freedom
Franziska Hild, Marcel Pfeiffer
The implementation of the ellipsoidal statistical Bhatnagar-Gross-Krook (ESBGK) method in the open-source particle code PICLas is extended for multi-species modeling of polyatomic…
Implementation of Asymptotic Preserving Discrete Velocity Methods into the Simulation Code PICLas
Félix Garmirian, Marcel Pfeiffer
The Bhatnagar-Gross-Krook (BGK) model of the Boltzmann equation allows for efficient flow simulations, especially in the transition regime between continuum and high rarefaction. H…
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…
