TCL model implementation into Code_Saturne




Validation

The version of the TCL implemented in saturne is such that results matches those from the version of Stream of Tania (STREAM_Tania) in a channel flow (Re*=395).

Results on the periodic hill case (Reh=10590, 150x172 2D mesh)

Tests of the TCL with and without the Yap correction in the dissipation rate equation. The general conclusion at light of those results is that the current CS implementation of the TCL model yield strongly underpredicted ww quantiies leading to strongly erroneous values of A.
