On the Gap-Tooth direct simulation Monte Carlo method
… and evaluates Gap-tooth DSMC (GT-DSMC), a direct Monte Carlo simulation procedure for dilute gases combined with the Gap-tooth method of Gear, Li, and Kevrekidis. The latter was proposed as a means of reducing the computational cost of microscopic (e.g. molecular) simulation methods using …

Assessment of high-fidelity collision models in the direct simulation Monte Carlo method
… more complex physics to be modeled in the DSMC method. Beginning with the first paper on DSMC in 1963, 30,000 collision events per hour were simulated using a simple hard sphere model. Today, more than 10 billion collision events can be simulated per hour for the same problem. Many new and more …

Modeling reactive rarefied flows in Chemical Vapor Infiltration using Direct Simulation Monte Carlo
Chemical Vapor Infiltration (CVI) is a key method for fabricating silicon carbide (SiC) matrix composites. Gas-phase precursors flow into a porous fiber, react, and deposit to form the ceramic matrix. Deposition quality and rate are strongly influenced by surface reactions, depending on …

Deterministic numerical simulation of the Boltzmann and kinetic model equations for classical and quantum dilute gases
… from the Boltzmann equation, the numerical simulation of the Boltzmann equation is indispensable in the study of moderately and highly rarefied gas. We aim to develop an accurate and efficient deterministic numerical method to solve the Boltzmann equation. The fast spectral method [1], …

Modelling of satellite control thruster plumes
… programmes: (a) the Simons model, (b) the Method of Characteristics (MOC), and (c) the Direct Simulation Monte Carlo method (DSMC). The first two methods are derived from continuum equations whilst the third adopts a discrete particle approach.<br/>Several DSMC schemes exist for treating …

Simulation of rocket plume impingement and dust dispersal on the lunar surface
… of the complex physics are simulated using the direct simulation Monte Carlo method. A descent engine of comparable size and thrust to the Lunar Module Descent Engine is simulated because it allows for direct comparison to Apollo observations. Steady axisymmetric impingement was first studied …

Modeling of shock boundary layer interactions and stability analysis using particle approaches
… including rarefied, slip, continuum regimes. The direct simulation Monte Carlo (DSMC) method, a well-known stochastic approach to solving the Boltzmann equation, provides high-fidelity molecular transport and thermal nonequilibrium, commonly seen in strong shock-shock interactions and inherently …
