Fast Large-Eddy Simulation of Low Reynolds Number Flows over a NACA0025

摘要

BLADES of small vertical-axis wind turbines operate at lownReynolds numbers and undergo continuous dynamic stall [1].nTo improve the design of these blades, flow features such as separ-nation and turbulent transition need to be captured accurately,which isnstill a challenge for most of the computational fluid dynamics codes.nIn a first attempt to simulate these flows, a code is developed andntested on a static airfoil at a low Reynolds number.
