摘要 以D1Q3模型为例,研究了一维情况下具有特定离散速度的Boltzmann-BGK方程的解,当时间趋于无穷大时,可由Burgers方程自相似解叠加表示出来. Take D1Q3 Model as an example,it was showed that under suitable assumption the solution of discrete Boltzmann-BGK equations can be constructed in terms of the self-similar solutions of Burgers equation as time tends to infinity.
