STUDY TO IMPROVE PHASE TRANSITION PATTERN OF WATER VAPOR ON SURFACE OF HEAT EXCHANGER

摘要

In this paper, there are some physical and mathematics models established about the Dynamic Processes of phase transition of water vapor. The effectiveness has been proved theoretically to prevent the frostdeposit in a cryosurface covered with high hydrophobic film and to enhance the drop condensation inside of condensation covered with low interface energy complex film The models refer to indicate/incorporate the dynamic process of an intermediate stage before the frost layer or water film(drops) is formed on the surface.
