Hi,
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,
Joe
