How does the maximum Power equation change if there's an angle to the way the wind falls into the wind turbine's blades?
Example, when it falls vertically to the blades, it's
Pmax= 8/27Sρu13
But if there's for example an angle of θ=150ο then what? My book says you need to do S=Scosθ, but cos(150o)= -0.89. Which is negative and doesn't make sense for the Power to be negative?
I thought maybe I should do S=πR2=π(Rcosθ)2 instead. Is that wrong or what am I supposed to do?
