Speed of wind turbine to the speed of air

[dioross]

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?..

Hello there,

I can provide some information on the relationship between wind speed and the rotation speed of a wind turbine. The formula that relates these two variables is known as the Betz limit, which states that the maximum possible efficiency of a wind turbine is 59.3%. This means that the rotation speed of a wind turbine cannot exceed 59.3% of the incoming wind speed.

In terms of the design of the generator and propeller, it is important to consider the specific wind conditions of the location where the turbine will be installed. Factors such as average wind speed, direction, and turbulence can affect the design and performance of the turbine. Additionally, the size and shape of the propeller blades can also impact the efficiency of the turbine.

I recommend consulting with a wind energy expert or conducting further research on specific design considerations for wind turbines. I hope this helps and good luck with your project!

Best regards, :)
