Heat Exchanger modelling problem

September 30, 2006, 19:31

Hi, I am new to fluent and I have run into problem modelling a very simple air to air heat exchanger.

I have created volume mesh for 1 outer tube and 1 inner tube, hot air passes thorugh the inner tube and cold air passes through the outer tube, the tubes are to be made of aluminum.

In order to model this problem with fluent should i set the interface between the tubes as "WALL" or "INTERFACE"? and can someone please explain what the "SHELL CONDUCTION" when setting the wall BC?

thx
