概要 | The present study discusses on the latest lattice Boltzmann methods (LBMs) for micro/nano fluidics to evaluate their applicability to micro/nano-flows in complex geometries. The discussed micro flow (mu-flow) LBMs are based on the Bhatnagar-Gross-Krook (BGK) model and the multiple relaxation-time (MRT) model. The presently chosen mu-flow BGK LBM (BGK-1 model) consists of the diffuse-scattering wall condition with the single relaxation time sensitized to the Knudsen number whereas the mu-flow MRT LBMs are combined with the diffusive bounce-back wall condition (MRT-1 model) and the bounce-back and specular-reflection condition (MRT-2 model). The simulated flow cases are canonical force-driven Poiseuille flows at 0.01 <= Kn <= 10 and a flow around an obstacle (a square cylinder) situated in a nanochannel at Kn approximate to 0.1. The second-order truncated system (nine discrete velocity model for two dimen'sions: D2Q9 model) is applied for the simulations. |
