Power coefficient, X and Y forces on the full turbine

The left graphs show the quantities as function of $\theta$ (angle from the top, 12 o'clock in the counter clockwise direction), and the right graphs show the quantities as function of the flow incidence angle

Power coefficient, X and Y forces on a single blade

The left graphs show the quantities as function of $\theta$ (angle from the top, 12 o'clock in the counter clockwise direction), and the right graphs show the quantities as function of the flow incidence angle

Single blade vs. full turbine

The solid line correspond to the full turbine data and the dashed line corresponds to the single blade data

Standard deviation

As those results were phase-averaged, it is interesting to look at the standard deviation, which gives an idea of the resolved / modelled turbulence proportion
