Abstract
The experimental results for gravity-controlled condensation of ethanol and water vapor mixtures on a horizontal tube are presented. Dropwise, drop and streak, and ring wise condensations are observed for the ranges of ethanol vapor mass fraction W<1∞>=0.20.5, 0.50.7 and 0.750.8, respectively, while smooth-film condensation takes place for the ranges of W1∞=00.2 and W1∞=0.81. Previous theoritical results for the heat transfer coefficent by the present authors based on the two-phase boundary layer theory are valid for the case of smooth-film condensation, while 20 to 60% higher heat transfer coefficient values are obtained for the other cases.
