DSMC simulations of chemically reacting gas flows have generally employed procedures that convert the macroscopic chemical rate equations to reaction cross‐sections at the microscopic level. They therefore depend on the availability of experimental data that has been fitted to equations of the Arrhenius form.

DSMC Simulation of Microfilter Elements
Micro-Electro-Mechanical Systems (MEMS), 1999Abstract Direct Simulation Monte Carlo (DSMC) analysis of micro-filter elements for collection of airborne particles is considered in this paper. Three filter elements with different dimensions were simulated. Boundary conditions were chosen to simulate an array of filters.

Parallel Implementation of a Corrected DSMC Method
2001In the paper it is suggested a correction of the Bird's algorithm in the DSMC method. It takes account of real distribution of collision events inside the time steps Δt and actual trajectories for the collided particles there thus diminishing asymptotical order of the error in time evolution from O(Δt) to O((Δt)2).

The early development of the DSMC method for the computer simulation of rarefied gas flows was made difficult by the slowness of the early computers, barely adequate procedures and molecular models, and a general lack of acceptance of the method. Computer speeds have increased by orders of magnitude more than would have been expected at that time and ...

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.

Detonation in Microchannel by the DSMC Method
42nd AIAA Thermophysics Conference, 2011A 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.

DSMC Calculations for The Double Ellipse
1991Rarefied flow about the double ellipse for test case 6.4.1 has been calculated with the direct simulation Monte Carlo (DSMC) method of Bird. The freestream conditions used in the numerical simulation assumed the flow to be in equilibrium at a temperature of 13.3 K, a velocity of 1.86 km/s, and a density of 1.729×10−5 kg/m3.

DSMC methods for multicomponent plasmas
AIP Conference Proceedings, 2012A 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.
