Lattice Boltzmann Simulation of Micro-scale Couette Flow of Two-component Gas Mixtures in the Slip Regime

 Lattice Boltzmann method (LBM) is considered as a promising numerical method for simulating the micro-scale flows. In this work, the LBM is employed to simulate the micro-scale Couette flow of two-component gas mixtures in the slip regime. The bounce-back and full diffusive boundary condition is proposed to deal with the gas-wall interaction. Based on the simulations, linear velocity profiles and obvious slip at the wall are observed, which are affected by the molar fraction, gas components, and Knudsen number. In comparison with the molar fraction and gas components, the Knudsen number has a more significant effect on the velocity profiles. The LBM provides an efficient way to capture the flow behavior of the micro-scale Couette flow of two-component gas mixtures. Furthermore, the proposed LBM can also be used to simulate other complex micro-scale flows of two-component gas mixtures.
