Question Heat pipe simulation in CFX

abymathew is on a distinguished road
Hi all,
I trying to do simulation of heat pipe kept in a heat sink. It is a closed copper tube with water inside. Inside the heat pipe water is there which gets heated and in the middle portion of the pipe changing to vapor phase and condenses on the far ends of the pipe. This copper tube is kept in an Aluminium case with fins on one side(bottom side). The fins are cooled by air.

In this model both condensation and evaporation is taking place inside the closed tube. More than one type of fluid domain is present ie. one domain is the fluid inside the copper tube and the other is the air domain that helps in cooling the fins.

I have never done this kind of problem before. I have only handled conduction and convection. Can anyone please help me with what type of modelling i should use and an insight into the same ?.

Multiphase models are much more complex than single phase, and multiphase models with phase change are much harder again. You should expect to spend quite a while coming up to speed on these models before you can do your simulation.

Have a look at the CFX documentation and tutorials and read the academic literature on similar models like yours.
