Hello, first I want to thanks to everyone in this Forum. I got many helpful informations...
I'm doing convection cooling. I want to cooling 500K cylinder with 200K air. (Transient)
I used "Initialization" to set air temperature 200K, "patch" to set cylinder temperature 500K.
Air is contained by walls, I gave "Heat flux"=0 boundary conditions for thoese walls, so they are adiabatic.
Air and cylinder contacting walls are coupled.April 7, 2022 at 10:36 amRobAnsys EmployeeCheck the heat flux through the coupled wall. After 20s how much heat do you expect to be transferred, if you then look at the solid heat capacity how much should that reduce the temperature?

Thank you for replying.
That was the way to think I should follow! I'll try your advice.
I don't know how to check them, but there must be some way.
Thank you very much!

That's the way to think! I'll try your advice.
April 7, 2022 at 11:52 amDongwooChoiSubscriberThank you for replying
I don't know why my comments are gone when I tried to edit them!
Anyway, that's how should I think about this proble! I'll try your advice
Can I get any advice about temperature gradient problem too?
Thank you very much

Re the gradient - if the heat flux is low such that there isn't enough heat to give a temperature gradient you won't see one. You're also displaying over the full range, try focussing on 495-500K and separately 200-300K.
