hi everyone
I am trying to simulation a heat pipe procedure by ansys fluent 16 or 17.
I use VOF model with evaporation-condensation mass transfer and set a polynomial equation for saturation temperature and define latent heat according to fluent tutorial and I impose the density of vapor phase as Ideal gas .
The bubbles visible in evaporation section but in condensation section we have only vapor phase without any liquid phase in condensation wall. note that even when the temperature of mixture in condensation section is below than saturation temperature the phase of fluid is vapor.
I am tried mixture model and again this problem happened.
please help.
thank you
