Abstract

Results are presented of scale-resolving Zonal RANS-IDDES and pure RANS computations of a turbulent wake exposed to adverse pressure gradient. The RANS–IDDES is performed with the use of the NTS code of SPBPU, and the RANS computations are carried with the use of the TAU code of DLR. It is shown that none of the considered RANS models (two linear eddy viscosity models and a full differential Reynolds stress transport model) is capable of reproducing the mean wake characteristics and turbulent statistics predicted by the RANS-IDDES. Accumulated RANS-IDDES database may be used for improvements of RANS models.
