Marangoni effect - Wikipedia
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 [ 1 ] (or Bénard–Marangoni convection ).
What Is the Marangoni Effect? - COMSOL
2015年7月2日 · The Marangoni effect takes place when there is a gradient of surface tension at the interface between two phases – in most situations, a liquid-gas interface. The surface tension typically changes due to variations in solute concentration, surfactant concentration, and temperature variations along the interface.
Marangoni flows are those driven by surface gradients. In general, surface tension σ depends on both the temperature and chemical composition at the interface; consequently, Marangoni flows may be generated by gradients in either temperature or chemical composition at an interface.
Marangoni propulsion technique arises in the natural world: certain water-walking insects eject surfactant and use the resulting surface tension gradients as an emergency mechanism for avoiding predation.
Marangoni number - Wikipedia
The Marangoni number (Ma) is, as usually defined, the dimensionless number that compares the rate of transport due to Marangoni flows, with the rate of transport of diffusion.The Marangoni effect is flow of a liquid due to gradients in the surface tension of the liquid. Diffusion is of whatever is creating the gradient in the surface tension.

Marangoni Convection - SpringerLink
2014年1月1日 · The Marangoni effect refers to the variation of surface tension of a liquid with temperature (thermocapillarity) or with the concentration of a surfactant (solutal Marangoni effect). The variation of surface tension in turn leads to convective motion of …
COMSOL 6.2 - Marangoni Effect - COMSOL Multiphysics
Marangoni convection occurs when the surface tension of an interface (generally liquid-air) depends on the concentration of a species or on the temperature distribution. In the case of temperature dependence, the Marangoni effect is also called thermo-capillary convection.

Marangoni effect - (Multiphase Flow Modeling) - Fiveable
The Marangoni effect directly shows that differences in surface tension can create fluid motion, as fluid flows from areas of lower surface tension to areas of higher surface tension. This movement is driven by the need to balance surface energy across an interface.
