摘要: Abstract In dropwise condensation most of the heat is transferred by active droplets whose sizes are below a certain characteristic value so that thermal conduction resistance inside them may become negligible. this paper local transfer coefficient determined experimentally at very part condenser surface which covered solely droplets. The rate increase in condensate volume domain newly exposed coalescence between was analyzed from high-speed high-magnification cine film record surface. By assuming complete coverage droplets, obtained way equated to interfacial coefficient. As result, water estimated around 0.5.
