I'm currently having a bit of an issue selecting the type of aerofoil I would want to use in my ridge mounted wind turbine honours project. I want to select a high lift generating aerofoil at low speeds, but I am overwhelmed with the options.
The blade will be fixed and have no moving flaps, the wind speeds will be controlled with a variable stator upstream of the blades in order to provide a wind speed as close as possible to the optimal speed for maximum lift generation which would allow for a higher rpm and thus more power generation.
I know the parameters of the wind tunnel I will be testing in and the wind speeds I could encounter in real world applications. Through my research it seems that liebeck aerofoils are the way to go, if I'm right which one? If I'm wrong, what questions should I be asking and what should I be doing differently?
Are there any online sources I should read through before I make my choice or should i just pick a standard blade with a high CL/CD? I would have liked to have two choices in order to evaluate which would be the preferred design.
In real world application wind speeds will range from 1 m/s to 25 m/s. Therefore, I will replicate these speeds in the wind tunnel.
