构造了用于Belosov-Zhabotinsky反应的格子Boltzmann模型。通过对使用多组分的分布函数满足的格子Boltzmann方程,进行多重尺度Knudsen数展开,得到了模型的平衡态分布函数的各向同性解。作为算例,给出随机初始条件下反应区域内的靶型波的模拟结果,再现了Belousov-Zhabotinsky反应的经典结果。 The lattice Boltzmann model for the Belosov-Zhabotinsky reaction is constructed. The multi-scale Knudsen number expansion is achieved by using the lattice Boltzmann equation which satisfies the distribution function of multiple components. The isotropic solution of the equilibrium distribution function of the model is obtained. As an example, the simulation result of the target wave in the reaction region under the random initial conditions is given, and the classical results of the Belousov-Zhabotinsky reaction are reproduced.
