离散 Ｂｏｌｔｚｍａｎｎ⁃ＢＧＫ 方程解的长时间特性研究

Large-time Behavior of Solutions of Discrete Boltzmann-BGK Equation

    摘要
  • 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

     

    Abstract: 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
