Results are presented of scale-resolving computations of mean and turbulent (including the dissipation rate of turbulent kinetic energy) characteristics of the turbulent wake of a flat plate subjected to Adverse Pressure Gradient (APG). The computations are performed in the framework of a zonal RANS-LES model for two configurations. In the first one, APG is created by a plane symmetric diffuser and in the second one by a system of two pairs of thin liner foils specially designed for this purpose. In the both cases a volumetric synthetic turbulence generator is used for creating turbulent content at the inlet of LES sub-domain. High accuracy of results of the simulations is supported by their weak sensitivity to grid-refinement. Obtained detailed data on the wakes’ characteristics may be used for validation and improvement of RANS turbulence models as applied to the considered class of flows.
Keywords: turbulent wake behind flat plate, unfavorable pressure gradient
Mots-clés : zonal RANS-LES computations.
