The heat and mass transfer processes driven by ultra-thin liquid films are widely used in energy, chemical engineering, aerospace and other fields. The intensification and regulation on those processes are a common and fundamental scientific problem in energy and power engineering areas. The main objective of this proposal is to investigate the microscopic mechanism, influenced by interface structure and fluid physicochemical properties, Marangoni effect and so on, on rapid wetting, spreading and ripple fluctuation of ultra-thin liquid films, the special flow pattern and heat-mass transport characteristics are desired to be established as preliminary theory on particular transport behaviors of ultra-thin liquid films. Rapid spreading mechanism and regulation strategy of ultra-thin liquid films induced by superwetting interface would be explored in this project, as well as the fluctuation behavior and evolution pattern, so as to establish the predictive spatial transport model of ultra-thin liquid films induced by multi- ripple units. Further research on regulation behavior for production, spreading and fluctuation of ultra-thin liquid films would be carried out, which can promote the foundation of new mechanism on high-efficiency heat-mass transfer. Moreover, some typical transport processes will be conducted so as to interpret the detailed strategies for improving heat-mass transfer efficiency. This project is of great significance on the investigations and applications of advanced heat enhancement technologies, such as phase-changing heat transfer, innovative equipment design for energy power transfer, gas-liquid two-phase flow and heat transfer, spacecraft water recovery and micro heat pipe.
