Abstract
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. In this study, it was found that addition of the heat transfer additive beyond the solubility limit assisted Marangoni convection occurrence, but should not be a criterion for Marangoni convection inducement.
