| 英文摘要 | Steam condensation on the surface of a solid is a widely observed mode of energy transfer in nature and various industrial applications. The condensation efficiency is closely related to the material properties and geometric morphology of the solid surface, as well as the method of liquid removal. Despite many surface modification strategies having been employed to enhance condensation, most experiments use gravity to remove condensate, thereby limiting the application scenarios. Here, we report a method without relying on gravity that uses superhydrophilic and superhydrophobic coatings as well as spiked surfaces to achieve efficient steam condensation and rapid removal of the liquid. We reveal that hydrophobic spiked surfaces facilitate the dropwise condensation, while hydrophilic bottom grooves promote liquid spreading, and the suction in capillary gaps can promptly remove the condensate liquid. Thus, a high heat flux density of 920.7 kW/m2 and a high condensation efficiency 94% are obtained in an open environment. Additionally, we demonstrate that the pipe with a spiked inner surface has a significantly higher condensation efficiency compared to the smooth pipe. This finding provides a new approach for efficient steam condensation technology in phase-change heat transfer applications. |
