DSMC methods for multicomponent plasmas

AIP Conference Proceedings, 2012
A general approach to Monte Carlo methods for Coulomb collisions is proposed. Its key idea is an approximation of the Landau-Fokker-Planck equations by the Boltzmann equations of a quasi-Maxwellian kind. This means that the total collision frequency for the corresponding Boltzmann equation does not depend on velocities.

A Practical Variance Reduced DSMC Method

AIP Conference Proceedings, 2011
The goal of this work is to develop a practical method for simulating low‐signal kinetic (and small‐scale) gaseous flows. These flows have recently received renewed attention in connection with the design, manufacturing, and optimization of MEMS/NEMS devices operating in gaseous environments; they are typically described using the Boltzmann equation ...

Parallel DSMC method using dynamic domain decomposition

International Journal for Numerical Methods in Engineering, 2005
Summary: A general parallel direct simulation Monte Carlo method using unstructured mesh is introduced, which incorporates a multi-level graph-partitioning technique to dynamically decompose the computational domain. The current DSMC method is implemented on an unstructured mesh using particle ray-tracing technique, which takes the advantages of the ...

Detonation in Microchannel by the DSMC Method

42nd AIAA Thermophysics Conference, 2011
A detonation wave propagation along a two-dimensional 1-mm-width channel in hydrogenoxygen stoichiometric mixture has been simulated by Direct Simulation Monte Carlo method. A detailed chemical kinetic mechanism for 6 species has been implemented and all the chemical reactions have been modeled at a level of molecular collisions.

Efficient CUDA implementation in the DSMC method

AIP Conference Proceedings, 2012
An algorithm of DSMC computations on several graphic processor units (GPUs) is proposed. The efficiency of this algorithm is demonstrated. The computational efficiency of one GPU is equivalent to 10-30 processors of a computational cluster based on multicore CPUs.

DSMC/Continuum hybrid methods

AIP Conference Proceedings, 2001
In the past decade a number of hybrid methods, which combine Direct Simulation Monte Carlo (DSMC) with computational fluid dynamics (CFD) algorithms, have been proposed. The motivation for developing such hybrids is primarily the computational expense of DSMC relative to continuum CFD schemes.
