Implementation and Extension of the Variance-Reduced BGK Method in PICLas
Leon Teichröb, Félix Garmirian, Marcel Pfeiffer
Traditional particle-based kinetic methods, such as DSMC, suffer from prohibitive computational cost in low-signal flows, where the deviation from thermodynamic equilibrium is smal…
Crank-Nicolson BGK Integrator for Multi-Scale Particle-Based Kinetic Simulations
Marcel Pfeiffer, Félix Garmirian, Tobias Ott
Solving the Bhatnagar-Gross-Krook (BGK) equation with a stochastic particle approach enables efficient and flexible simulations of flows in the transition regime, between continuum…
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…
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…
