HELICIEL PRO CFD video tutorial, film C5

Two rotors modeled in the Heliciel designer by the blade element method (BEM), simulated in the Heliciel PRO CFD bench: a 4 m, 3-blade wind turbine at 166.8 rpm in a 5.5 m/s wind, and a 16 m, 2-blade tidal turbine in a 2.4 m/s tidal current. Flow lines slowed down by the rotor, pressure on the blades, wake in vertical and cross cuts, thrust on the wind turbine blades 4 % from BEM, torque flagged not reliable by the bench, and 454,000 N on the tidal turbine structure with the rotor really turning.
