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 on the full turbine
Vertical force on the full turbine
Horizontal force on the full turbine

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

Power coefficient on 1 single blade
Vertical force on 1 single blade
Horizontal force on 1 single blade

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

Power coefficient (comparison full turbine (solid) vs single blade (dashed))
Vertical force (comparison full turbine (solid) vs single blade (dashed))
Horizontal force (comparison full turbine (solid) vs single blade (dashed))

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

Standard deviation of the power coefficient on 1 single blade
Standard deviation of the vertical force on 1 single blade
Standard deviation of the horizontal force on 1 single blade
