Web9 de dez. de 2016 · In analogy with the molecular viscous stress in laminar flows, the anisotropic part is approximated by relating it to the resolved rate of strain tensor as in Eq. In OpenFOAM, the subgrid scale viscosity is computed as where is a model constant whose default value is and is the grid size that defines the subgrid length scale. Web26 de dez. de 2024 · In a pseudo-spectral code [ 20] LES with the DSM overestimated the Reynolds stress anisotropy, while LES with the EAM produces results closer to DNS from the buffer region up to the outer region, with a reasonable prediction of the inner peak amplitude for the streamwise normal stress.

Just a side note, LES in OpenFOAM uses the implicit tophat filter at the first filter level (Delta). In this case, no explicit filtering is done, it are basically the grid and the discretization schemes that take care of the filtering. small eared owl
