Steven J. Plimpton,Stan Gerald Moore,Arnaud Borner,A. K. Stagg,Timothy P. Koehler,John R. Torczynski,Michail A. Gallis +6 more
TL;DR: SPARTA as mentioned in this paper is an implementation of the Direct Simulation Monte Carlo (DSMC) method for modeling rarefied gas dynamics in a variety of scenarios, and it can operate in parallel at the scale of many billions of particles or grid cells.

Molecular-Level Simulations of Turbulence and Its Decay.
Michail A. Gallis,Neal Bitter,Timothy P. Koehler,John R. Torczynski,Steven J. Plimpton,George Papadakis +5 more
TL;DR: The direct simulation Monte Carlo method, a molecular-level technique for simulating gas flows that resolves phenomena from molecular to hydrodynamic (continuum) length scales, is applied to simulate the Taylor-Green vortex flow, providing strong evidence that molecular- level methods for gases can be used to investigate turbulent flows quantitatively.

Comparison of interparticle force measurement techniques using optical trapping
TL;DR: In this article, the authors compare measurements of interparticle forces applying both optical tweezers and direct force measurements to a model system of polystyrene particles in an aerosol-OT (AOT) hexadecane solution where the screening lengths are very large.
