我们开发了具有灵活比热比的可压缩纳维-斯托克斯方程的格子玻尔兹曼模型。给出了几个数值结果，它们与纳维-斯托克斯方程的相应解非常吻合。此外，还提出了一种显式的有限差分格式用于数值计算，可以在大库朗数下进行稳定的计算。
We have developed a lattice Boltzmann model for the compressible Navier-Stokes equations with a flexible specific-heat ratio. Several numerical results are presented, and they agree well with the corresponding solutions of the Navier-Stokes equations. In addition, an explicit finite-difference scheme is proposed for the numerical calculation that can make a stable calculation with a large Courant number.
