Аннотация

The present paper describes the approach implemented in EDF in-house CFD tool Code_Saturne in order to couple several instances of the code, running on separate computational domains with different turbulence models such as RANS and LES. After a brief discussion on data exchange between at least two instances of the code and on the numerical interpolation between two overlapping unstructured grids, the paper focuses on the Synthetic Eddy Method (SEM) implemented in Code_Saturne. Finally, the RANS/LES tangential coupling is treated by using the SEM to generate a fluctuating field departing from RANS quantities.
