my name is Joe and I am a new member in this forum.
The system I try to simulate is made out of two discs with rotational periodicity. During operation the disc rotate with different speed but the same colinear rotational axis. During operation there is a gap between the discs in axial direction with a fluid flow. The fluid has a different (higher) temperature compared to the disc. The important thing is the heat transfer from the fluid to the discs.
Actually I implemented a model with 2 solid (discs) and a fluid domain (fluid) in between. The domains are connected by fluid-solid-interfaces (GGI). The boundary surface between fluid and solid is wall with a rotational speed.
Because the fluid has a inhomogeneous haet distribution, to solve the Problem accurate, a rotation of the solid discs is needed to get the correct heat distribution on the discs. The problem is that i do not know how to realize a rotation of the solid discs.
It would be great, if somebody has some detailed information to solve the problem.
Thank you so far,
Do what want to solve the temperature distribution in the disks? In that case you need a CHT simulation (conjugate heat transfer, ie a fluid domain and a solid domain) where the solid domain also rotates. I think you need V12 for this, I don't think it is supported in V11. Ask your CFX support people for the V12 beta.
I contacted the support and it is also possible to "Enable Beta Features" in Advanced CFD.
Edit -> Options -> CFX-Pre --> Enable Beta Features.
It is now possible to use beta feauters including rotation of solid domains.
Thank you for your information.
