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. |

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. |
