Graphics processing unit based direct simulation Monte Carlo

SIMULATION, 2011
The direct simulation Monte Carlo (DSMC) is a computational method for fluid mechanics simulation in the regime of rarefied gas flow. It is a numerical solution of the Boltzmann equation based on an individual particle basis. Accurate simulations typically require particle numbers in the range of hundreds of thousands to millions.

Direct simulation Monte Carlo method for particle coagulation and aggregation

AIChE Journal, 2000
AbstractA Monte Carlo simulation technique developed describes dispersed‐phase systems with emphasis on coagulation and aggregation. The method does not use particle trajectories, but is based on the transformation of known collision frequencies into collision probabilities of particle pairs.

Direct Monte Carlo simulation of the ocean surface

IGARSS '98. Sensing and Managing the Environment. 1998 IEEE International Geoscience and Remote Sensing. Symposium Proceedings. (Cat. No.98CH36174), 1998
Various elements of the ocean surface can focus or defocus light working as the lenses. In the latter case an underwater object can be hidden. When the ocean surface is focusing light, a strong return signal can be detected and misinterpreted as the underwater object at a given depth. Therefore, modeling the electromagnetic wave scattering on the ocean

Nonlinear acoustic simulations using direct simulation Monte Carlo

The Journal of the Acoustical Society of America, 2004
In the simulation of fluid dynamics, one can either treat the fluid as a continuum or as discrete particles. Although popular for acoustics, the continuum model is limited to small Knudsen numbers (the ratio of mean free path to a length scale). Particle methods are necessary for, but not limited to, problems with Knudsen numbers greater than 0.1 ...

Enabling Simulations of Droplets with the Direct Simulation Monte Carlo Method

2020
The evaporation behaviour of droplets changes with their size. Most numerical tools to simulate evaporation phenomena of droplets solve macroscopic models such as the Navier-Stokes equations. These numerical tools have an advantage in computational effort compared to tools solving microscopic models such as the Boltzmann equation.

Direct Monte Carlo Simulation of Oxygen Dissociation Behind Shock Waves

36th AIAA Thermophysics Conference, 2003
A study is conducted on the nonequilibrium dissociation of Oxygen behind shock waves. Numerical simulations are performed by means of the DSMC method. A state-to-state vibrational kinetic model is adopted specified by a set of microscopic cross sections.
