Applied Scientific Research Aims and scope Submit manuscript

Abstract

Most of the theoretical studies in dropwise condensation have based their analysis on the principle that the heat transfer rate limiting mechanism in dropwise condensation is the conduction of heat through drops. Based on this principle, Fatica and Katz presented shape factor values for droplets and these values have been used by other studies.
