VR-PIC: An entropic variance-reduction method for particle-in-cell solutions of the Vlasov-Poisson equation
Victor Windhab, Andreas Adelmann, Mohsen Sadr
We extend the recently developed entropic and conservative variance reduction framework [M. Sadr, N. G. Hadjiconstantinou, A variance-reduced direct Monte Carlo simulation method f…
Treatment of long-range interactions arising in the Enskog-Vlasov description of dense fluids
Mohsen Sadr, M. Hossein Gorji
The kinetic theory of rarefied gases and numerical schemes based on the Boltzmann equation have evolved to the cornerstone of non-equilibrium gas dynamics. However, their counterpa…
A Continuous Stochastic Model for Non-Equilibrium Dense Gases
Mohsen Sadr, M. Hossein Gorji
While accurate simulations of dense gas flows far from the equilibrium can be achieved by Direct Simulation adapted to the Enskog equation, the significant computational demand req…
Wasserstein-penalized Entropy closure: A use case for stochastic particle methods
Mohsen Sadr, Nicolas G. Hadjiconstantinou, M. Hossein Gorji
We introduce a framework for generating samples of a distribution given a finite number of its moments, targeted to particle-based solutions of kinetic equations and rarefied gas f…
An efficient jump-diffusion approximation of the Boltzmann equation
Fabian Mies, Mohsen Sadr, Manuel Torrilhon
A jump-diffusion process along with a particle scheme is devised as an accurate and efficient particle solution to the Boltzmann equation. The proposed process (hereafter Gamma-Bol…
