http://web.mit.edu/1.63/www/Lec-notes/Surfacetension/Lecture4.pdf WebA 2D model of laser melting consisting of heat transfer, hydrodynamic flow, surface tension, and a free surface motion was established. A physical field simulation of the laser melting process was performed, and the effect of steady magnetic field parameters on the internal flow and temperature fields of the melt pool was analyzed and validated by experiments. …

What Is the Marangoni Effect? - COMSOL

WebDear all, Hello, I am going to simulate marangoni effect due to concentration gradient in COMSOL. I have coupled two-phase flow physic (both field-set and level-set) and transport of diluted species. The Marangoni number is the nondimensional number that gives the ratio between the thermocapillary effect and the viscous forces. is the the length scale of the system in m, is the maximum temperature difference across the system in K, is the dynamic viscosity in kg/s/m, and is the thermal diffusivity in m … See more 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 … See more It is important that the Marangoni effect is not confused with the pure capillary effect. Capillary forces are responsible for a meniscus at an interface, or the shape of a water droplet.
