need help with heat transfer in cfx
hi
I'm using cfx to represent air flow inside an engine intake system and I want to apply cooling at certain parts of this system I want to know how can I apply heat flux (+ve or -ve) in cfx please help thanks |
guys please anyone

What type of heat flux do you want to apply? |
simply all I want to do is apply on the intake system geometry (imagine its a primitive cylinder for simplification now) cooling using peltier's cells (electric refrigeration cells) and see how this affects the density of air and the mass flow rate at the outlet .
so its cooling for certain parts of the cylinder wall or even setting its temperature constant and passing air through it and then seeing how this affects air properties |
The simplest approach then would be to make the walls have a defined heat flux equal to the heat extracted by the coolers. Simple.
