摘要
The instability of a meniscus due to a Marangoni flow is investigated in the case of a mixture of two liquids of different volatility and surface tension. We propose a theoretical description of this behavior which predicts the wavelength of the instability, in agreement with the experiments of Vuilleumier et al. performed with ethanol-water mixtures and for isooctane-decane solutions.
