An Improved-Accuracy DSMC Algorithm
AIP Conference Proceedings, 2008The Direct Simulation Monte Carlo (DSMC) method is widely considered to be both an accurate and general method for simulating non‐continuum gas flows and a computationally intense method because of its molecular nature. Recently, the originator of the method proposed a new variant of DSMC, termed “sophisticated DSMC.” This new DSMC algorithm aims at ...

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.

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.

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.

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.

Forced Couette Flow Simulations Using DSMC
42nd AIAA Aerospace Sciences Meeting and Exhibit, 2004computational molecules are allowed to move and collide in the physical space. Macroscale flow properties can be obtained by sample averaging. Figure 1 shows a sketch describing the physical reasoning of the discrete modeling approach of fluid motion.

DSMC models for H2O condensation process
AIP Conference Proceedings, 2015Two DSMC models of cluster formation are developed for simulation of water condensation process. The first model is based on the modified classical nucleation theory and the second on the kinetic theory. The relaxation of the size distribution function is calculated for the spatially homogeneous case, where the water monomer parameters are kept ...

Gases Mixing in Microchannels Using DSMC
ASME 3rd International Conference on Microchannels and Minichannels, Parts A and B, 2005Mixing in microchannels is an important problem because the flow is always in laminar mode even though the velocity could be high. This present paper is trying to expose the inherent effect factors on micro gases mixing by using the direct simulation Monte Carlo (DSMC) method at high Knudsen numbers.

DSMC simulation of ionized rarefied flows
23rd Fluid Dynamics, Plasmadynamics, and Lasers Conference, 1993Recently a renewed interest has been exhibited in understanding contamination and space environmental effect in the LEO range of 200 to 600 km as well as in low density microelectronics manufacturing technologies. Realistic simulations must model the physics of the highly coupled effects of neutral and charged particle flows, thermodynamic ...
