气-液两相流传递研究

Study of gas-liquid two-phase flow transport processes

阐述了在气－液两相流传递研究方面的工作，包括气升式环流系统中的流体力学和传递、降液膜流动下的传热和传质、“载气蒸发”技术的研究和开发等．并由研究惰气冲击冷剂液浴中放热壁面强化冷却的操作机理，提出了“界面汽化热阱增强传热的原理”，发展了用电化学方法与传热测定同时进行分离出“热阱效应”的实验方法．还阐述了在相际传质和化学法测定两相接触面积方面的工作．

The work of 'gas-liquid two-phase flow transport processes' conducted by theauthors is described. It includes: the hydrodynamics and transport phenomena in the gas-liftrecirculated system, the heat and mass transfer of a falling liquid film in a vertical circular tubeand the research and development of a novel process of 'gas carrying evaporation'. From asystematic study of the mechanism of the enhanced cooling by inert gas impinging on heated wallin liquid coolant bath, the 'principle of heat transfer augmentation by interfacial vaporization heatsink' is proposed. Moreover, the work on the 'interfacial mass transfer' and the measurementof gas-liquid contacting area by chemical method developed by the authors is also presented.
