hi i am unable to simulate the heat pipe in fluent which has two phase flow is it required to give pressure outlet also for multi phase i am unable to use the porous zone too

So what exactly is your question?
The skeleton ran out of shampoo in the shower.

i want simulate heat pipe with fluent,any body know how simulate this case in fluent?i know i must use VOF model for this,but i cant simulate boiling in pipe...
pls help regard

multiphase flow -superheated steam

I am using multi-phase mixture model.. my fluid are superheated steam(as a primary phase) and water-liquid (as a secondary phase). The problem was property of steam(enthalpy) wat i need supposed to get is not getting
(for e.g) In my boundry condition enthalpy value of a steam from a steam table is h=3000kj/kg but wat i am getting from cfd results is nearly h=1200kj/kg...
how to fix the problem ...

Heat Pipe Simulation in Fluent

i am trying to design a heat pipe in ansys fluent.
temperatures at evaporator and condensor are 50degree and 25 degree respectively.
liquid fillinf ratio is 70%.
so here are the conditions i gave in my simulation.
i chose double precision, transient pressure based solver.
model- multiphase-volume of fluid with energy equation on.
In phase interaction - mass - number of transfer mechanisms - 1
Evaporation-condensation with both 0.1 frequency
and saturation temperature of 320K.
Surface tension of 0.072 n\m with wall Adhesion.
Boundary Conditions - Evaporator as Pressure inlet
Guage pressure: 0
Initial Guage Pressure: 0
Condensor as Pressure outlet
Guage pressure: 0
Back flow temperature: 0
Adiabatic as Wall
No slip wall
contact Angle: 70
I am not getting any proper result with these conditions. Rest all are kept default values.
Please Anyone of you guys are familiar with the design, it would be great if you could help me
