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。
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, the function of the density distribution of Poiseuille pipeline flow and the simulating solution was presented. the relaxation time τ was determined under the small Knudsen number . The solution of the simulation was in agreement with the analytical solution.
