Résumé

In absorption systems, the performance of heat and mass transfer can be significantly enhanced by adding heat transfer additives to the working solution pairs. The small addition of heat transfer additives changes the magnitude of surface tension, which causes interfacial turbulence by the Marangoni effect leading to a higher heat and mass transfer performance. The surface tension of working solution has a significant effect on not only heat and mass transfer characteristics but also the flow mechanism.
