Direct simulation Monte Carlo method for particle coagulation and aggregation
AIChE Journal, 2000AbstractA 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), 1998Various 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, 2004In 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 ...

Direct Monte Carlo Simulation of Oxygen Dissociation Behind Shock Waves
36th AIAA Thermophysics Conference, 2003A 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.

Enabling Simulations of Droplets with the Direct Simulation Monte Carlo Method
2020The 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.

Implementing direct Monte Carlo simulation in batch mode
Computers and Electronics in Agriculture, 1995Abstract A flexible, easily implemented procedure for direct Monte Carlo simulation of deterministic computer models is presented. The procedure is implemented in two stages, with the required random variates generated first using a general-purpose pre-processor module, and model-specific linking routines employed to generate input files and provide ...
