摘要

The accelerating effects of surface-tension-driven Marangoni convection on interfacial heat and mass transfer were demonstrated by the absorption of steam by quiescent aqueous LiBr solution with n-octanol additive. The effect caused by surfactant additive on quiescent liquid absorption can be quantified approximately to that caused by artificial agitation in liquid without additive. The effect of artificial liquid agitation on the absorption system in the presence of n-octanol was also studied to reveal the interaction between the induced interfacial turbulence and the inherent bulk turbulence. The experimental results show that interfacial turbulence caused by surfactant additive plays a dominant role in a system of less intense inherent bulk turbulence. (from Authors)
