Comment on the paper J. G. Zhou, Rectangular lattice Boltzmann method, Phys. Rev. E 81, 026705 (2010)
摘要:
分析和数值计算表明,矩形网格上的格子Boltzmann模型导致流体动量的各向异性耗散,因而不能恢复纳维-斯托克斯方程。因此,它不能用于流体动力学的模拟。
英文摘要:
It is shown both analytically and numerically that the suggested lattice Boltzmann model on rectangular grids leads to anisotropic dissipation of fluid momentum and thus it does not recover Navier-Stokes equations. Hence, it cannot be used for the simulation of hydrodynamics.
