根据模拟条件的不同,混合的拉格朗日粒子可以用作直接数值模拟(DNS)、大涡模拟(LES)或过滤密度函数(FDF)方法。我们估计与DNS,LES和FDF制度的主要参数,并证明,在一定的条件下,在该文件中指定的,模拟使用不同的混合模型接近DNS限制。
Lagrangian particles with mixing can be used as direct numerical simulations (DNS), large eddy simulations (LES), or filtered density function (FDF) methods depending on conditions of the simulations. We estimate major parameters associated with the DNS, LES, and FDF regimes and demonstrate that, under certain conditions specified in the paper, simulations using different mixing models approach the DNS limit.
