The dynamics of charged particles in electromagnetic fields is an essential component of
understanding the most extreme environments in our Universe. In electromagnetic fields of …

This paper presents a hybrid particle-in-cell (PIC) fluid approach to model the interaction of a
plasma plume with a spacecraft and/or any nearby object. Ions and neutrals are modeled …

A new computational framework for a coupled PIC-DSMC tool using multiple GPUs to model
the kinetic behavior of electrons in plasma plumes is presented in this work. The disparate …

Grid-based kinetic models are promising in that the numerical noise inherent in particle-
based methods is essentially eliminated. Here, we call such grid-based techniques a direct …

The expansion of a rarefied axisymmetric plume emitted by a plasma thruster is analyzed
and compared with a 3D Cartesian-type and a 2D cylindrical-type simulation code, both …

A kinetic description for electronic excitation of helium for principal quantum number n
$\leqslant $4 has been included into a particle-in-cell (PIC) simulation utilizing direct …

The non-uniform grids in the axisymmetric coordinate system pose a significant challenge
for electrostatic particle-in-cell/Monte Carlo collision (PIC/MCC) simulations because they …

We propose a new scheme for simulation of collisions with multiple possible outcomes in
variable-weight DSMC computations. The scheme is applied to a 0-D ionization rate …

In particle-in-cell simulations, excessive or even unfeasible computational demands can be
caused by the growth of the number of particles in the course of prolific ionization or …

The stochastic weighted particle method (SWPM) is a generalization of the Direct Simulation
Monte Carlo (DSMC) method where particle weights are variable and dynamic. SWPM is …
