Hello, my name is Luthfi, my team is doing a project related to the modelling of multistage rotor of water vortex turbine. We want to model the flow of water liquid through channel, basin, and the vortex rotates the rotor. We used spaceclaim to make the design, made the rotation domain enclosing the rotor or applying multi reference frame, and set the fluid domain here (pictures of "design"). We then used fluent meshing and set the fluid-fluid boundary so that the fluid can flow through the fluid domain of the basin to the domain of rotation enclosing the rotor (pictures of "meshing"). We set up the parameters by using steady state with velocity in the inlet of channel, then apply absolute rotational speed to the rotation domain, and relative 0 m/s velocity to the rotor (pictures of "setup"). When we did the simulation, the streamline result cannot penetrate the rotation domain (pictures of "result") though. What should we do to fix this?

We would really appreciate any advice from the expert as we are new in this field. Thank you

Best regards,
Luthfi

Advice? Don't post in multiple places!

I'm sorry. I just didn't know which forum right for this topic. I will discontinue this post

Do you mean that the fluid is not flowing accross the regions or it is just about the post-processing that the streamlines aren't penetrating in the rotation domain?

Yes it's just the result of streamline in post processing, but is it still ok Sir?

I am sorry Sir, but could you reply it in another link that Mr. Robert gave?

 

Thank you
