RÉSUMÉ
The partially integrated transport modeling (PITM) method viewed as a continuous approach of hybrid RANS/LES with seamless coupling is used to derive a subfilter-scale stress model in the framework of second moment closures (SMC) applicable in a rotating frame of reference. In this work, the pressure-strain correlation term is modeled from a physical standpoint in an invariant form under an arbitrary change of non-inertial frame of reference. As a result of the simulations, it is found that the subfilter-scale stress model reproduces fairly well the mean features of turbulent rotating channel flows performed on coarse grids with a reduction of the computational cost.
