WebJan 1, 2014 · Marangoni effects may play a major role during the formation and detachment of a drop or bubble, since the formation of such a drop naturally involves the formation of a new surface which needs to be covered by surfactant. In this situation, surfactant coverage of the new interface occurs gradually as it is formed, and the rate at which the new ... The Marangoni effect (also called the Gibbs–Marangoni effect) is the mass transfer along an interface between two phases due to a gradient of the surface tension. In the case of temperature dependence, this phenomenon may be called thermo-capillary convection (or Bénard–Marangoni convection). See more This phenomenon was first identified in the so-called "tears of wine" by physicist James Thomson (Lord Kelvin's brother) in 1855. The general effect is named after Italian physicist Carlo Marangoni, who studied it for his … See more Since a liquid with a high surface tension pulls more strongly on the surrounding liquid than one with a low surface tension, the presence of a … See more Under earth conditions, the effect of gravity causing natural convection in a system with a temperature gradient along a fluid/fluid interface is usually much stronger than the … See more • Plateau–Rayleigh instability — an instability in a stream of liquid • Diffusioosmosis - the Marangoni effect is flow at a fluid/fluid … See more As an example, wine may exhibit a visible effect called "tears of wine".
