This paper reviewes the advances in the investigation of the solid-liquid-interfacial-energy- difference (SLIED) effect on the heat transfer processes of filmwise, transition (filmwise and dropwise co-existing) and dropwise condensation modes for pure vapor and mixture vapor in the presence of non-condensable gas. The heat transfer models with consideration of the SLIED effect of each condensation mode mentioned above are proposed. A comparison of the theoretical results and the experimental data is presented for confirming the significance of this novel mechanism for heat transfer enhancement. Other heat transfer enhancing technologies are also introduced.
