文摘

The Improved Delayed Detached Eddy Simulation and polyhedral mesh are utilized. Power coefficient and wake velocity are compared between experiments and simulations. Improved Delayed Detached Eddy Simulation shows more vortices under dynamic stall. Different scales of flow separations are distinguished by these two models.
