Abstract
Film and drop condensation are important processes in technics. This article includes the features of macroscale heat transfer intensifiers under film condensation, microscale and nanoscale heat transfer intensifiers under drop condensation. It is noted that condensation heat transfer may be influenced by the wall material. The mechanism underlying this influence is the nonuniform distribution of the wall temperature in the case of a low heat conduction coefficient. Based on the research results, a dependence of the wetting angle from the combined coating consisting of 7 alumina oxide and water repellent is obtained.
