Abstract:

A literature survey of the published information on the effect of coatings and surfaces on dropwise condensation was carried out. The survey revealed that research to date in promoting dropwise condensation has been limited mostly to small scale laboratory experiments. There appears to be a serious lack of data on methods of application of various dropwise promoters, useful life of promoters, effective concentration, and frequency of promoter renewal. This lack of information is highlighted by the total absence of dropwise condensation as a factor in design of condensers in industry. Recommendations are made to initiate an experimental program to evaluate the effects of vibrating the condenser surface upon dropwise condensation and the coefficients of heat transfer.
