FEMTA micropropulsion system characterization by DSMC
AIP Conference Proceedings, 2019CubeSats with compact, low-power attitude-control systems open up opportunities for deep-space missions as well as cost-effective constellation-based satellites targeting remote sensing and communication applications. Film Evaporation MEMS Tunable Array (FEMTA) is a micropropulsion technology that employs thermally-controlled surface tension in a ...

AIP Conference Proceedings, 2001
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 ...

DSMC Convergence Behavior for Fourier Flow
AIP Conference Proceedings, 2005The convergence behavior of Bird’s Direct Simulation Monte Carlo (DSMC) method is explored for near‐continuum, one‐dimensional Fourier flow. An argon‐like, hard‐sphere gas is confined between two parallel, fully accommodating, motionless walls of unequal temperature.

Efficient DSMC Collision-Partner Selection Schemes
AIP Conference Proceedings, 2011The effect of collision‐partner selection schemes on the accuracy and the efficiency of the Direct Simulation Monte Carlo (DSMC) method of Bird is investigated. Several schemes to reduce the total discretization error as a function of the mean collision separation and the mean collision time are examined.

Dsmc Procedures Ina Homogeneous Gas
1994Abstract The DSMC procedures for the simulation of a representative set of intermolecular collisions are best derived and demonstrated in the context of a homogeneous or ‘zero-dimensional’ gas. However, in order to make the procedures directly useful as subroutines in the later programs, the homogeneous gas is divided into a one ...

Oxygen transport properties estimation by DSMC-CT simulations
AIP Conference Proceedings, 2014Coupling DSMC simulations with classical trajectories calculations is emerging as a powerful tool to improve predictive capabilities of computational rarefied gas dynamics. The considerable increase of computational effort outlined in the early application of the method (Koura,1997) can be compensated by running simulations on massively parallel ...

SUPREM-DSMC Version 1.0 User's Manual
2000Abstract : SUPREM-DSMC is a scalable, parallel, reacting-flow Direct Simulation Monte Carlo code for modeling nonequilibrium and collisional gas dynamic processes in complex geometries of interest to DoD. This manual is intended to document installation and operation of the SUPREM-DSMC package. This manual is presently under development.

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.

A detailed DSMC surface chemistry model
AIP Conference Proceedings, 2014This work is aimed at development of detailed molecular surface chemistry models for DSMC method, their implementation into the SMILE++ software system, verification and validation. An approach to construction of DSMC suface chemistry models based on macroscopic reaction rate data was proposed.
