SpletThis behaviour has been attributed to the Marangoni effect 6, whereby interfacial flow is established by gradients in interfacial tension causing an increase in one case, and a … Splet12. apr. 2024 · Marangoni condensation is a dynamic process involving the movement of condensate droplets, which can be attributed to the Marangoni effect resulting from a temperature gradient [31]. Deans et al. [ 25 ] observed the droplet movement in Marangoni condensation on a horizontal tube, and they found that the maximum droplet velocity was … building management system standards
Marangoni effect on the impact of droplets onto a liquid-gas interface …
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). Prikaži več 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 … Prikaži več 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 … Prikaži več Under earth conditions, the effect of gravity causing natural convection in a system with a temperature gradient along a fluid/fluid … Prikaži več • 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 … Prikaži več As an example, wine may exhibit a visible effect called "tears of wine". The effect is a consequence of the fact that alcohol has a lower surface tension and higher volatility than water. The water/alcohol solution rises up the surface of the glass lowering the Prikaži več A familiar example is in soap films: the Marangoni effect stabilizes soap films. Another instance of the Marangoni effect appears in the behavior of convection cells, the so-called Prikaži več • Motoring Oil Drops Physical Review Focus February 22, 2005 • Thin Film Physics, ISS astronaut Don Pettit demonstrate.
