摘　　要：综述了纳米流体强化气液传质的一些研究成果,总结了纳米流体强化气液传质,纳米流体强化气液传质机理及其他强化技术和纳米流体共同作用强化气液传质的研究进展,主要从纳米微粒的Brownian运动、输运效应、溶液导热系数的增强及表面张力的下降引起的Marangoni对流等因素对强化机理给予了解释,并预测了未来三个主要的研究方向。Nanofluids have been researched by many scholars for the enhancement of gas-liquid mass transfer. The latest research developments of gas-liquid mass transfer enhancement and mechanisms, as well as nanofluids with other methods together enhancing gasqiquid mass transfer were summarized. The mechanisms of nanofluids enhancing gas-liquid mass transfer were given from several aspects, including Brownian motion, grazing effect, the augment of thermal conductiv- ity and Marangoni convection because of surface tension decreasing. The three research directions of nanofluids enhancing gas-liquid mass transfer were proposed.
