I am trying to simulate the behaviour of a vertical axis wind turbine in fluent (v19.2). In order to do this, I have created a rotating mech around the turbine. At this stage, it is possible to apply a rotation speed but I would like to know if there is any function enabling the free rotation of the turbine, as the aim of the study is to determine at which speed it can rotate.
Thank you in advance for any advice.

you can use the option 6DOF, it allows the part to move thanks to the fluid forces.
A tutorial on YouTube in order to use it:

Good to see you pitching in. We encourage you to continue on this.
Yes, you will need to use 6dof.
Following video may give you some idea about 6dof.

I guess so. See the post Raef turbine tutorial (still w/o a solution).

Thank you very much for your help! I will try it soon.

I have followed the tutorial indicated by Max4. I have just one issue and it disable the solving process. In "Dynamic mesh", "Six DOF properties", I entered a mass of 0.05kg and an inertia of 5e-5 (obtained via SolidWorks). The problem is that the program automatically set the value of the mass to 0 when I close the window. I have tried "5e-2" instead but the result remain the same...
Is there any solution?

If the object only rotates, and doesn't translate, there is no need for the mass, the Moment of Inertia is all that is needed for the dynamics equations.

hey greg018 , i am working on same problem , i want wind to rotate the turbine but i am very confused how to approach and how to do this problem as i am new to ansys fluent please help me so that i can get solution for my problem ...
