Hello to every body.
What I'm interested in is the simulation of pool boiling via fluent software. Mixed multiphase model is used. During my simulating bubbles have formed but while my input is a certain heat flux the temperature of the heated surface is much more than what it should be as Rohsenow correlation as Fig 8 in attached article, although my geometry and inputs are similar.
I was wondering if someone could guide me. How can I improve the precision of the simulation results?
Best regards.
It is a matter of the wall function U use
Tray to make modification to the wall function and thermal diffusivity at the wall
The reason of not getting the temperature might be :
1) Check the heat flux is constant or not .
2) Check what boundary conditions you have given to walls of boiling pool.
3) Check the properties of the fluid, ( Just when nucleation of bubble starts )
