Speed of wind turbine to the speed of air

Click For Summary

Discussion Overview

The discussion revolves around the relationship between incoming air velocity and the rotational speed (rpm) of a wind turbine. Participants explore the design considerations for turbine blades and generator parameters, focusing on aerodynamics and design principles.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant inquires about formulas relating air velocity to turbine rpm, indicating a need for design parameters.
  • Another participant suggests that the turbine speed depends on blade design and wind speed, advising to start with expected mean wind speed and desired turbine rotation speed.
  • A third participant notes that the relationship is influenced by turbine size and the lift-to-drag ratio of the blades, emphasizing the importance of understanding aerodynamics rather than seeking a simple formula.
  • A follow-up question asks for insights on blade design, indicating a desire for practical design guidance.

Areas of Agreement / Disagreement

Participants express varying perspectives on how to approach the relationship between wind speed and turbine design, with no consensus on a specific formula or method. The discussion remains unresolved regarding the best approach to design considerations.

Contextual Notes

Participants mention factors such as blade design, turbine size, and aerodynamics, but do not provide specific assumptions or definitions that could clarify their statements. The discussion lacks detailed mathematical relationships or established formulas.

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?..
