Looudspeaker cooling

Please login with a confirmed email address before reporting spam

Hi there!
I'm studying heat transfer in a loudspeaker.
I'm not concerned in acoustic behaviour.
I need to model the air motion induced by the cone harmonic displacement.
I tried to follow the peristaltic pump procedure, without success. 2D axially symmetric approach is OK.
However, I'm actually not interested in the structural analisys of the cone and the voice coil, it would be enough if I could impose a harmonic displacement onto the corrisponding fluid boundary.
I'm not familiar with the moving mesh module, and I'm not sure about the subdomain and boundary settings.
Same problems when I come to set conditions over fluid boundaries corresponding to moving walls.
And what about the axis (mesh is deformed along it as well)? Which conditions shoul I set for the different modes?
Any hint?

Thanks

P.S. I can't share the model (not even the geometry): proprietary.
