Abstract
Analytical solution for the axisymmetrical lattice Boltzmann model is obtained for the lowMach number cylindrical Couette flows. In the hydrodynamic limit, the present solution is in excellent agreement with the result of the NavierStokes equation. Since the kinetic boundary condition is used, the present analytical solution using nine discrete velocities can describe flows with the Knudsen number up to 0.1. Meanwhile, the comparison with the simulation data obtained by the direct simulation Monte Carlo method shows that higherorder lattice Boltzmann models with more discrete velocities are needed for highly rarefied flows.
