Introduce a torque on Fluent

      Hi, everyone!


      I'm working on a project, giving by my teachers at the university, about a turbine engine. I'm trying to create a model to study Tesla turbine.


      Tesla turbine is an unconventional turbine that uses fluid properties such as boundary layer and adhesion of fluid on series of smooth disks keyed to a shaft, like below.


      I have the geometry and the mesh. But i want to impose a torque at the axis turbine on fluent. I have search in ANSYS help, but it isn't easy to understand. How can i do it?


      I know, i can do it on CFX, but i never work with it, so i wanted to know if i can do it on Fluent.


      Thanks,


      André

      Thank you Raef Kobeissi!


      I have another problem, now. Is about the convergence.


      When i introduce pressure-inlet and pressure_outlet or outflow, the initialize solution don't converge. Is this a problem with the mesh? Or with the boundary conditions?


      Thanks

      Hello Did you try to initialise from bounday instead of hybrid initialisation? If your mesh is coarse it could also be a problem.
