| Abstract: | Rayleigh-Bénard-Marangoni (RBM) effect has an important influence on gas/liquid or liquid/liquid mass transfer process happened in absorption, distillation, extraction, evaporation and so on. But up to now, the comprehension to RBM effect is still far from satisfying the request of theory and practice although RBM effect strengthens the mass transfer process in general. Experimental and theoretical study on RBM effect will intensify the understanding of microcosmic mechanism of mass transport and promote the practical application in chemical engineering. The results of experimental and theoretical study on RBM effect were reviewed and the future study methods were discussed as well. |
