A Dual-mesh Hybrid Les/rans Framework with Implicit Consistency

INTRODUCTION The high computational cost of Large Eddy Simulation (LES) for wall-bounded flows at high Reynolds numbers still is a major hurdle for applications to practical flows in industry and nature [3]. To overcome this difficulty, various hybrid LES/RANS methods have been proposed, of which the most widely used one is Detached Eddy Simulation (DES). Recently, Xiao and Jenny [4] developed ...

An extensive study on LES, RANS and hybrid RANS/LES simulation of a narrow-gap open Taylor-Couette flow

The present paper concerns a numerical benchmark of various turbulence modelings, from RANS to LES, applied to Taylor-Couette-Poiseuille flows in a narrow gap cavity for six different combinations of rotational and axial Reynolds numbers. Two sets of refined Large-Eddy Simulation results, using the WALE and the Dynamic Smagorinsky subgrid scale models available within an in-house code based on ...
