Modelling Loop Heat Pipe (effective thermal conductivity)
 

Hello. I am a user of FloEFD, often modelling heat pipe and vapor chamber as a heat spreader by assigning an effective thermal conductivity, rather than trying to simulate the actual phase transformation.
I was wondering if anyone could give me an advice on how to model a loop heat pipe, where the structure is separated into liquid and vapor lines. In this case, how can I model it using effective thermal conductivity? Or is there any other method of modelling the loop heat pipe?

Thanks for your help.

Hello Joe

I didn't model heat pipes yet. But maybe could it be a possibility to model the loop heat pipe as an assembly. By using several parts fitted together in the assembly you could assign different effective thermal conductivities to these different parts.
