| Abstract: | It is significant to know the distribution and flow of condensate on the fin surface directly for comprehending the mechanism of condensation and the calculation of liquid film.Visualization experiment of condensation over a horizontal fin tube is performed.Based on the measurements,the diameter of the condensate drop on the fin surface was measured by image processing software.The law of distribution and flow of condensate drop was obtained. |
