Hi evrybody, Can someone help me ? I want to calculate the cooling of a hot(900K) moving solid in a channel subject to a colder flow (460K). If you want, I could give you precise details on my model.

Thanks for evryone.

Hi!

for uniform velocity and axial direction of moving in a channel without change in cross section area, you can let your solit object stay and move the walls!

For the dynamic mesh it's ok but heat transfert don't work.

I tried to create "Interfaces" but the heat isn't transfered to the fluid. I tried to create just walls between the fluide and the solid. Fluent created automatically walls shadow. I don't know which boundary condition I'have to input.

Thanks if you can help me
