我们表明，离散的晶格效应必须考虑在引入力的晶格玻尔兹曼方程。然后提出了强迫项的表示。在此基础上，从格子Boltzmann方程出发，通过Chapman-Enskog展开，导出了Navier-Stokes方程。其他几个现有的力的治疗方法也进行了研究。
We show that discrete lattice effects must be considered in the introduction of a force into the lattice Boltzmann equation. A representation of the forcing term is then proposed. With the representation, the Navier-Stokes equation is derived from the lattice Boltzmann equation through the Chapman-Enskog expansion. Several other existing force treatments are also examined.
