Surface tension-driven instability of thin liquid film of lithium bromide aqueous solution absorbing water vapour.

Author(s) : FUJITA I., HIHARA E.

Summary

Experimental and theoretical approaches are conducted to reveal the mechanism and the condition for the onset of the instability. A 2-dimensional infrared thermometer is employed to measure temperature fluctuation on the vapour-liquid interface. The instability occurs dominantly owing to the temperature effect rather than owing to the concentration effect where n-octanol is added to the solution as a surfactant; thus, surface tension varies according to temperature as well as concentration.
