Advances in an open-source direct simulation Monte Carlo technique for hypersonic rarefied gas flows
Hypersonic vehicles that travel through rarefied gas environments are very expensive to design through experimental methods. In the last few decades major work has been carried out in developing numerical methods to capture these types of flows to a certain degree of accuracy. This accuracy is …

Weighted particle variance reduction of Direct Simulation Monte Carlo for the Bhatnagar-Gross-Krook collision operator
… stochastic particle method for high-speed rarefied gas flows-simulates the Boltzmann equation using distributions of representative particles. Although very efficient in producing samples of the distribution function, the slow convergence associated with statistical sampling makes DSMC …

An investigtion into the ability of a kinetic particle-based solver for study of gas flows in micro-scale structures
… in the fields of MEMS and porous media. These flows occur in pathways whose width is comparable to the mean free path and thus, are classified as rarefied gas flows. Assuming continuum and resorting to traditional CFD techniques leads to results with severe reservations while, deterministic …

Modeling reactive rarefied systems using a novel quasi-particle Boltzmann solver
… solver, such that it can adequately model the rarefied portion of an atmospheric reentry trajectory. Direct Simulation Monte Carlo (DSMC) is the conventional solver for such conditions, but struggles to resolve transient flows, trace species, and high level internal energy states due to …
