Analysis of Moment Closures Using -Divergences for Rarefied Dynamics with Binary Collisions and Their Galerkin Discretizations
Michael R. A. Abdelmalik, Irene M. Gamba, Torsten Keßler +1
This work introduces a robust deterministic framework for approximating solutions of the Boltzmann equation with binary collisions by discretizing their dependence on time, positio…
Multidisciplinary benchmarks of a conservative spectral solver for the nonlinear Boltzmann equation
George J. Wilkie, Torsten Keßler, Sergej Rjasanow
The Boltzmann equation describes the evolution of the phase-space probability distribution of classical particles under binary collisions. Approximations to it underlie the basis f…
Vlasov-Poisson system tackled by particle simulation utilising boundary element methods
Torsten Keßler, Sergej Rjasanow, Steffen Weißer
This paper presents a grid-free simulation algorithm for the fully three-dimensional Vlasov--Poisson system for collisionless electron plasmas. We employ a standard particle method…
Galerkin-Petrov approach for the Boltzmann equation
Irene M. Gamba, Sergej Rjasanow
In this work, we propose a new Galerkin-Petrov method for the numerical solution of the classical spatially homogeneous Boltzmann equation. This method is based on an approximation…
A novel formulation of nonlocal electrostatics
A. Hildebrandt, R. Blossey, S. Rjasanow +2
The accurate modeling of the dielectric properties of water is crucial for many applications in physics, computational chemistry and molecular biology. This becomes possible in the…
