Heat Pipe Simulation

kpk

Hi,

I am trying to Simulate Heat pipe as Conduction model (Solid/ Hollow pipe),

I have Thermal resistance curve for the heat pipe from the manufacturer.

Is it possible to model the Heat pipe by specifying the thermal resistance in AcuSolve / HyperWorksCFD

I don't think I've seen a heat pipe simulation with AcuSolve.  Are you thinking to replace the working fluid evaporation/condensation portion with just the effective thermal resistance?  (That would probably need to be converted to anisotropic thermal conductivity - high in the pipe length direction, and lower in the cross directions.)

Hi acupro,

Thanks for the reply, you are right i am trying to replace the working fluid evaporation/condensation portion with only Effective thermal resistance.

I am not sure about giving Anisotropic thermal conductivity for bent Heat pipes (not straight) and inclined in position w.r.t to coordinate system.

You would probably need to apply heat flux to the relevant sections of the wall boundary, rather than thermal resistance.
