Abstract
A two-step kinetic/continuum approach has been used to study the ability of optical lattices to improve mixing rates of neutral gas mixtures. The kinetic step uses the direct simulation Monte Carlo method to model the gas-lattice interaction over the laser pulse period. The continuum step based on the solution of Navier-Stokes equations utilizes the kinetic solution as initial condition, and predicts the gas evolution at spatial and temporal scales larger than those associated with the optical lattice.
