Hi
Can anyone tell me which divergence scheme in openfoam to use for high reynolds number LES.

upwind cannot be used because of dissipation
linear cannot be used due to peclet number criteria ( too many number of cells to satisfy it)

I need a good validated scheme.

div(phi,U) Gauss linear;
is an standard option in unstructured LES solvers, however it is not the best. Higher order methods are less dissipative.
Upwind method can be used if you use implicit LES (Furbey et al.)
Peclet number is not an issue since the diffusion is not being solved explicitly.
Higher order central discretizations would've had the Peclet issue if it was the case.

I checked this scheme before. Since Iím working with OF v6 there is no such a scheme.
