Lagrangian scale-similaritydependent model湍流模型
-
LESGO(一个用fortran编写的基于伪谱法的开源大涡模拟求解器,主要用于大气边界层和风能的模拟,https://lesgo.me.jhu.edu/ )提到了两种LES湍流模型Lagrangian scale-similarity model和Lagrangian scale-dependent model。这两种模型似乎在大气边界层流动模拟用得较多,想请教一下OpenFOAM这边有和这两个湍流模型相关的资料吗?
注(https://lesgo.me.jhu.edu/subgrid.html ):
The Lagrangian scale-similarity model dynamically changes the Smagorinsky coefficient Cs,Δ(x,t) by test filtering the flow field at a larger scale, assuming scale invariance, and averaging over Lagrangian trajectories.
The Lagrangian scale-dependent model dynamically changes the Smagorinsky coefficient Cs,Δ(x,t) by test filtering the flow field at two larger scales and averaging over Lagrangian trajectories. Unlike the Lagrangian scale-similarity model, the Lagrangian scale-dependent model does not assume scale invariance. -
