WebThe surface tension gradient, a Marangoni stress, pulls more wine up the wall, and droplets that form fall back down by gravity. This is what we call the Marangoni effect. In addition to a change in concentration, temperature also causes a change in the surface tension. Most fluids demonstrate a normal thermocapillary, in which surface tension ...
WebThe resulting outward Marangoni stress enhances droplet spreading. On the other hand, evaporation of H 2 O, the second most volatile component ( V P H 2 O = 2.3 kPa) with the highest surface tension ( γ H 2 O = 72 mN ⋅ m -1 ), depletes H 2 O in the vicinity of the apparent contact line, thereby decreasing the local 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 gradient in surface tension will … See more Under earth conditions, the effect of gravity causing natural convection in a system with a temperature gradient along a fluid/fluid … See more • Plateau–Rayleigh instability — an instability in a stream of liquid • Diffusioosmosis - the Marangoni effect is flow at a fluid/fluid interface due to a gradient in the … See more As an example, wine may exhibit a visible effect called "tears of wine".
