Null-collision technique in the direct-simulation Monte Carlo method
The Physics of Fluids, 1986The null-collision concept is introduced into the direct-simulation Monte Carlo method in the rarefied gas dynamics. The null-collision technique overcomes the principle fault in the time-counter technique and the difficulties in the collision-frequency technique.

Direct simulation Monte Carlo method for an arbitrary intermolecular potential
Physics of Fluids, 2012A scheme to implement an arbitrary intermolecular potential into the direct simulation Monte Carlo method is proposed. To illustrate the scheme, two benchmark problems are solved employing the Lennard-Jones potential. Since the computational effort of the new scheme is comparable with that of the hard sphere model of molecules, it can completely ...

On an Axisymmetric Direct Simulation Monte Carlo Method
International Journal of Computational Fluid Dynamics, 2021This study proposes an application of the variable time step (VTS) method to solve the non-conservation of fluxes encountered in the conventional direct simulation Monte Carlo (DSMC) method in axis...

Mean scattering angle method for direct simulation Monte Carlo
Physical Review E, 2022In order to predict the postcollision velocities in the binary collision, one needs the deflection angle given by the solution of the trajectory equation of classical mechanics. In the direct simulation Monte Carlo, it has been conventional to assume that the scattering is isotropic taking the hard sphere scattering law (the variable hard sphere model).

On Direct Simulation Quasi-Monte Carlo Methods
40th Thermophysics Conference, 2008Equations derived from kinetic theory often express a desired quantity in terms of a probability density. For example, the Direct Simulation Monte Carlo (DSMC) method is a well-known powerful technique for computational rarefied gas dynamics. It uses an algorithm that begins with an initial distribution and, through random sampling, converges to a ...

Distributional Direct Simulation Monte Carlo Methods
10th AIAA/ASME Joint Thermophysics and Heat Transfer Conference, 2010The Direct Simulation Monte Carlo (DSMC) method has gained popularity in recent years for treatment of flows in which the assumptions behind the continuum equations of fluid mechanics break down. In traditional DSMC methods, simulated particles may possess only a single velocity. This representation leads to a nonphysical representation of the velocity

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.

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.
