cfd fluent simulation of heatpipe
 
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?

There is no need of using multiphase in heatpipe modeling ;)

hi all
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
 
Hii Everyone...
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 ...
