    Abstract

    Copyright © 2016 by the International Society of Offshore and Polar Engineers.The flow around a circular cylinder at Reynolds numbers near the drag crisis was numerically simulated based on a dynamic Smagorinsky Large Eddy Simulation (LES) model at two Reynolds of Re = 1.0 × 105 and 6.0 × 105. The flow structures and the hydrodynamic force on the cylinder were analyzed. The numerical results show that the results at Re = 1.0 × 105 follow the key feature of subcritical turbulent flow and the results with Re = 6.0 × 105 capture the main features of the supercritical flow. This demonstrates that the Dynamic Smagorinsky LES model is a suitable numerical method for exploring high Reynolds flow around a circular cylinder.
