DBM vs LBM
Does it mean the larger Kn , the high order of kinetic momentum is required and thus more velocity components are required? If so, does this limit the application of this model, as it normally requires much more memory space ?
How to validate the nonequilibrium effects?
Is the DBM a 2nd order method? How is its performance in capturing the shock waves? Thanks!
What range of Kn values does this simulation method cover, and can it compute things like wall slip, or is the no slip condition still imposed?
Can DBM apply in the simulation of rarefiled gas ?
是不是使用分子动力学模拟能够更精确地描述非平衡态统计力学?
统计力学中的相空间跟DBM 中的相空间是同一个含义吗?
DBM对流固耦合等边界条件有没有特殊的要求 ?
如果时间步长和空间步长取得越来越小,结果一定会越来越好吗?有没有可能变差 ?
要分清楚啥是平均分子间距,啥是平均自由程撒
TNE(热力学非平衡)值得研究吗?
评论:个人觉得高阶 f 分量的DBM 应该和高阶宏观方程对比,比如 Burnett, Super-Burnett等方程比较。求解这些高阶宏观方程,也会得到比 NS 方程更多的物理特征。???
DBM建模的基本考虑
DBM算得准吗?
算法模型 vs 物理模型
