摘　　要：正系统特征的双组份混合工质,具有Marangoni效应,即出现类似珠状凝结,提高传热效率,可减少换热器的金属消耗和减小其尺寸.本项目研制的双组份凝结换热实验台,通过改变蒸汽浓度、压力和流速等因素,研究了对具有正系统特征的二元混合工质的水平管外凝结换热的特性.Binary mixture of positive Systems, with Marangoni effect, which appears similar to dropwise condensation, improves the heat transfer efficiency, can reduce the heat exchanger metal consumption and reduce its size. This project developed bicomponent condensation heat transfer experiment, by varying the concentration of steam pressure and flow, including factors such as, for experiment on Marangoni condensation of binary mixtures was made on non-isothermal horizontal surface.
