Hi all
Here is my question I am trying to simulate with flow simulation a wind turbine (any model is not important)
However, I am beginning to doubt the feasibility of my attempt, but I will need more information about the region in rotation.
Here is my problem:
I try to make the software understand that it is the wind that will drive the blades of my wind turbine. The problem is that I don't know of any function that can fulfill this role.
Is it parameters in the "rotating region" that I need to change or is it the flow simulation wizard and check very specific parameters.
My goal is to be able to quantify the rotation speed and if possible the starting torque (but I think I can forget about him haha). For the connoisseurs, I am trying to determine the TSR (Tip Speed Ration) of different wind turbines.
Hoping that my pavement is intelligible
Do not hesitate to ask me for more details if necessary
Thank you in advance for your help ;-)
Hello @ Néophyte_SWFS
What you say is quite intelligible! but my meagre experience on this forum has allowed me to see that there are very few FlowSimulation specialists.
Note that what you are asking for is completely within the flow-simulation strings but the problem will be above all to have nickel propeller profiles and that is much more difficult.
Therefore, don't be surprised if there aren't many answers, because they are not related to the Betz Limit. But there are Joules where there are more losses and fewer responses.
Betz looks (as the wind turbines say)
PS: you have a lot of examples on youtube for rotating regions

Hi Zozo_mp
Thank you for your answer. I used the rotating regions a lot and clearly, apart from giving the information to the software that the propeller rotates, creates a vacuum and sucks in the fluid I didn't manage to do what I wanted (namely that it was the wind that drives the wind turbine). Basically, a fluid that would rotate a "rotating regin" and not the other way around, ahah ^^.
For having gone through a lot of tutorials I can't find my application :'(
PS: I saw your video and I'm afraid I didn't understand correctly, from 10:30 the guy applies a speed of 20 m/s... Is this my application? x) sorry but my oral comprehension of English is below level 0

Hello Néophyte_SWFS
So there "tong at the cat"!
That said, the spirit of flow simulation and modeling the flow of flows with, to give a dynamic side, the "rotating region" which allows as you know to see how the flow (particles) behaves when the object is not static but moving. Here is a helix shape in space.
I pointed out to you that, for what you want to do, namely [[ My goal is to be able to quantify the rotation speed and if possible the starting torque ]] that the main problem would be to have very strict wing profiles, especially if you want to compare different models of wind turbines. Especially since you will notice that to stop or slow down a wind turbine you just have to reorient the tip of the blade by a rotation of a few degrees.
That's why it seems to me that it would be better to look at MECAFLUX HELICIEL , which is really made for this.
May Aeolus, the son of Poseidon, help you in your project.
Kind regards
ahah thank you for your answer,
Unfortunately my school doesn't have mechaflux heliciel^^ but I know this software I covet it.
too bad I'll manage otherwise, I'm sure I'll find a way to trick the software =D
Thank you for giving me your time in any case and good luck to you;)
a plus =)
Kind regards
