| Abstract: | The recursion arithmetic from the tube inside is chosen as the measuring principle for the experiment. According to the principle, the experimental equipment system was constructed and the experimental data were obtained. It was discovered that the heat transfer coefficient of dropwise condensation decreases with the existence of non-condensing gases, the relationship between the heat transfer coefficient of dropwise condensation and Re value is influenced by many external factors. Finally, some rational suggestion was put forward in order to further improve and perfect the experimental system. |
