Alright I've tried searching for this answer online and in specific forums on this site to no effect, and ANSYS Workbench's help file is about as helpful as tits on boar hog.

Problem:

I have a pipe of some length and of some material. I have a fluid flowing through the pipe that is really hot at the inlet and has a low flow rate and only takes up a small portion of the pipe. This fluid comes out of another source into this pipe at the aforementioned big temperature. The pipe can radiate to the atmosphere and has a passive convection current on it. I have a temp condition applied to the entrance of the pipe of a certain temperature, and I can figure out setting up the convection and radiation conditions in ANSYS transient thermal just fine.

My issue is how do I model the fluid in the pipe as a heat source that eventually cools as it moves down the pipe. Do I create another part inside the pipe and set it to being a heat generating model with multiple zones or is there a more simple way to do this?

Any tips or advice would be greatly appreciated. The eventual point of the model is to figure out how long this pipe needs to be to cool the fluid to a certain temperature at the exit.

Thanks
Nin
