Rotational Speed . Wind Turbine
 

Hi guys,:):)
I am using ANSYS Fluent to simulate the flow and calculate the power output of a horizontal axis wind turbine. and I have seen some articles in this field.*
In most articles I've seen, there is an imposed rotational speed of the rotor of the wind turbine, which raises a question for me about the criteria for choosing the imposed rotational speed.*

any help, and I hope that my question is clear.*
