Computational Fluid Dynamics simulations were carried out in two and three spatial dimensions to assess the suitability of numerical models for the simulation of deep dynamic stall experiments. The numerical results were compared to pressure measurements and Particle Image Velocimetry flow surveys carried out on a pitching NACA 23012 airfoil. The pitching cycles considered as test cases reproduce the deep dynamic stall condition for a helicopter rotor retreating blade section. The comparison of the airloads curves and of the pressure distribution over the airfoil surface shows that a three-dimensional numerical model can better reproduce the experimental airloads behaviour during the pitching cycles. The three-dimensional simulation results...
