摘要
目前,格子Boltzmann方法已被广泛应用于模拟各种非线性物理方程。文中用D1Q2模型给出MKDV方程的带修正项的BGK型格子Boltzmann方法。通过对演化方程的泰勒展开并应用多尺度技术恢复了宏观方程。数值模拟表明文中所建立的模型是有效的。
Lattice Boltzmann method is recently developed numerical schemes for simulating a variety of physical systems in recent years. In this paper, a lattice BGK Moltzmann method of MKDV equation is described by the D1Q2 model. Through Taylor expansion and multi-scale technique, macroecopic equation is recovered. Simulating results indicate that the model is very effective.
