我们发展了一种构造格子Boltzmann方法(LBM)局部平衡函数的简单方法。这种新方法可以使LBM模型满足可变比热比的可压缩流动。文中给出了一维Sod流、一维Lax流和热Couette流的算例。用所提出的新方法得到了较好的结果，表明该方法有可能构造LBM的局部均衡函数。
We have developed a simple method to construct local equilibrium function for lattice Boltzmann method (LBM). This new method can make LBM model satisfy compressible flow with a flexible specific-heat ratio. Test cases, including the one-dimensional Sod flow, one-dimensional Lax flow and thermal Couette flow are presented. Good results obtained using proposed new method, indicate that the proposed method is potentially capable of constructing of the local equilibrium function for LBM.
