Condensation of vapour is needed in many of the Industrial applications like steam condensers, refrigeration etc. When vapour comes in contact with surface having temperature lower than saturation temperature, condensation occurs. When the condensate formed wets the surface, a film is formed over the surface and the condensation is called film wise condensation. When condensate does not wet the surface, drops are formed over the surface and condensation is called drop wise condensation. Surfaces with plain and low surface wettability lead to poor condensation process which means heat transfer rate and heat transfer coefficient is low. There are surfaces like Hydrophilic surfaces and hydrophobic pattern surfaces which help in increasing the heat transfer rate and heat transfer coefficient through material surface. By considering all the possible considerations we prepared a project which is used to find better surface for heat transfer through Biphilic surfaces by using condensation process.
