Speed of wind turbine to the speed of air

AI Thread Summary
The relationship between incoming air velocity and wind turbine RPM is complex and influenced by blade design and wind speed. To design an effective turbine, one should start with the expected mean wind speed and desired rotation speed, then focus on blade design. Key factors include the size of the turbine and the lift-to-drag ratio of the blades. There isn't a straightforward formula; understanding the aerodynamics of turbine blades is crucial. Proper design will ensure optimal performance based on these parameters.

hi!...
Does anyone know the relationship (i mean formulas) relating to the incoming air velocity to the rpm of a wind turbine?..i need to have a design in the generator part and also the parameters of the propeller..thanks!

best regards, :)

The speed of the turbine would depend on the blade design and the wind speed, you are looking at this the wrong way round, start with the mean wind speed you expect, decide what speed you want the turbine to rotate at and then design your blades.
 
It's related to the size of the turbine and the lift to drag ratio of the blades. There isn't a simple relationship - you have to know how big the turbine is and what the characteristics of the airfoil are. The best place to start is the aerodynamics of the turbine blades.
 
thanks for the reply :)..do you have an idea on the blade design?..or just a simple design?..
 

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
