Abstract

The role of the buoyancy force for the development of the auto-oscillations of the surface tension is considered by comparison of the oscillation characteristics for the corresponding pairs of fatty acids and aliphatic alcohols. The effect of buoyancy on the oscillation characteristics is negligibly small for systems with low solubility surfactants, such as octanol, octanoic acid or diethyl phthalate; however, the role of buoyancy increases with increasing solubility of the surfactant and should be taken into account for hexanol.
