can we incorporate evaporation at liq-vap interfac
 

Hi My problem involves transient natural convection analysis of liquid hydrogen which is partially filled in a cylindrical tank. It is subjected to different heating conditions. the space over liquid level is occupied by its vapour. I found that there is no provision for evaporation at the interface, as the temperature increases..if there is a chance for incorporating UDF inform.. thanking u so much prasanth
