摘要
Lattice Boltzmann Method(LBM)可用于计算气体动力学方程,通过浅水长波方程与气体动力学方程的比拟,可得到计算浅水长波方程的LBM。确定了LBM中微观状态函数的形式及随时间变化的方式,给出了一个一维算例,并与精确解作了比较。
Based on the equivalence between the aerodynamical equation and the shallow water long wave equation, the lattice Boltzmann method is proposed to simulate the shallow water wave equation. The evolution of the distribution function has been given. The numerical simulations are presented and compared with the exact solution.
