heat at wall

November 9, 2004, 13:46

I need to enter the heat in the wall of my seal. I wrote the speed and the wall moving ans statinary but I need the heat too and I don' t know how do it. Somebody can help me, please? Thank you

If you select Define -> Models -> Energy

And you activate Energy then go to Boundary Conditions -> wall , and here you go!!!

Thank you, but I have to write the heat by friction between both surfaces.Do you know how do it?

I think you have to calculate the heat because of friction before and then enter the heat as Heat Flux or Heat Generation Rate, probably at both walls. I have a similar problem. Two rotating discs that are in contact, and there is heat flux because of friction. But i haven't reach that point yet.

I am not sure about my answer. Good luck!! Anni
