Request: horizontal axis wind turbine
 
Hello guys I am new to this forum. I have a senior project and I am using ANSYS Fluent to simulate the wind turbine.
I am confused of how to start. I read a lot of tutorials and videos and do them but when I start with mine I lost.
I want to make a wind tubine that rotate according to the speed of the winf hitting the blades showing this simulation.
I tried to do dynamic mesh but I don't know if its correct. I tried to do UDF to allow the blades to rotor, also I don't reach what I need. I am reallly lost if you please help me how to start doing this.
What I am sure of is that I must have a transient state.
best regards
thanks

Try rotating frame of reference concept which is done by rotating the whole domain with certain RPM while the air at certain velocity enter the domain, then measure the output torque, then calculate the power using it.

thanks mezah for your reply
but i need more details on how to start. In addition i only have the wind speed and i need the wind speed to rotate the blades not to assume the rotational velocity

I think this post here is very good starting point
