摘要： 应用Lattice-Boltzmann方法,由7-Bit的FHP模型得到了描述粘滞流的N-S方程。在小Knudsen数条件下,给出了Poiseuille管流的密度分布函数和模拟解,确定了弛豫时间τ,模拟解与其解析解吻合。

Abstract: Navier-Stokes(NS) equations of viscosity flow were expressed with Lattice-Boltzmann method in low Mach number range and a 7 Bit-FHP model. The population distribution, thefunction of the density distribution of Poiseuille pipeline flow and the simulating solution was presented. the relaxation timeτwas determined under the small Knudsen number.The solution of the simulation was in agreement with the analytical solution.
Key words: Lattice-Boltzmann Method, Navier-Stokes equations, density distribution, poiseuille flow
