TAYLOR-COUETTE-POISEUILLE FLOWS: FROM RANS TO LES

Abstract

The present paper proposes a study of a Taylor-Couette-Poiseuille flow in a narrow gap between a rotor and a stator, using two different rotation rates. Refined Large-Eddy Simulation results, using the WALE model Nicoud & Ducros (1999), hold for reference data, whereas the efficiency of a RANS model, the Elliptic Blending Reynolds Stress Model (EB-RSM) (Manceau & Hanjali, 2002; Manceau, 2005), and a hybrid RANS/LES method, the so-called "Equivalent DES" (Manceau et al., 2010; Friess & Manceau, 2012) is studied.
