Abstract
Large-Eddy Simulations (LES) for an oscillating NACA0012 aerofoil at Reynolds number 1.35 × 105 have been performed to investigate the capability of a new approach of a One-equation SGS model. The phenomena of the oscillating aerofoil at higher amplitude angle (𝛼𝑎𝑚𝑝) is believed to produce deep dynamic stall in which strong non-equilibrium turbulence could also visible. Hence, a new approach of a one-equation SGS model is proposed where the coefficient of production term in the kSGS transport equation is defined dynamically. From the simulations, the leading-edge vortex (LEV), dynamic stall vortex (DSV), shedding mechanism and trailing edge vortex (TEV) are captured in this study.
