Large eddy simulation of a pitching airfoil undergoing deep dynamic stall

Representation of the flow field developed around a pitching airfoil under deep dynamic stall. This video shows how the large-scale Leading Edge Vortex is formed during pitch-up motion and it gets shed due to a Trailing Edge Vortex formed prior the maximum pitch angle is reached. Case simulated with the LES-solver Hydro3D and published in Journal of Fluids Engineering:
