The fidelity of DSMC method to analyze the aerothermodynamics of the pure continuum flow regime
International Journal of Thermofluids, 2020 The statistical probabilistic Direct Simulation Monte Carlo (DSMC) method was developed to interrogate the flow regime, in which thermal non-equilibrium exists and flow properties are non-continuous.

Stochastic DSMC method for dense bubbly flows: Methodology
Chemical Engineering Science, 2018 A stochastic Direct Simulation Monte Carlo (DSMC) method has been extended for handling bubble-bubble and bubble-wall collisions. Bubbly flows are generally characterized by highly correlated velocities due to presence of the surrounding liquid. The DSMC method has been improved to account for these kind of correlated collisions along with a treatment ...

Beyond direct simulation Monte Carlo (DSMC) modelling of collision environments [PDF]
, 2019 Direct simulation Monte Carlo (DSMC) models have been successfully adopted and adapted to describe gas flows in a wide range of environments since the method was first introduced by Bird in the 1960s.
