Modelling of Heat transfer
 
Hey everyone,

I need some help in modelling a system, where water flows through a Cu-pipe and heat is transfered through the walls of the pipe into a surrounding material.

Which modell shall i take for this? Thermal-transient? And how can I make the geometry so that Ansys knows what's which material? Also, I dont know how to combine a mass flow (water) with the heat transfer.

Help much appreciated...:rolleyes:

Greetings

please adress you problem in the fluent section. when you have walls, you can set their thickness and their materials in ansys...
