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. The typical size of a small droplet of liquid … See more First noted in the phenomenon of tears of wine, the Marangoni effect has been observed in various surface chemistry and fluid flow processes.

Characteristic magnitude of temperature gradient was taken 1 K (preliminary simulations) with γ = − 1.4769 ⋅ 10 − 4 N / ( m ⋅ K). This results in M a = 2.9 ⋅ 10 4, which implies that Marangoni convection completely dominates in the near-surface layer. thinkpad e480 efiWebCOMSOL激光增材制造 (熔池仿真)，采用动网格、层流、流体传热（相变）、非等温流动和马兰戈尼效应研究随位置及时间变化下的激光作用下的温度、流场、相变的变化情况 J你的名字我的姓氏 773 0 comsol 电磁铁仿真 无脑小明 6166 0 comsol仿真移动激光 熔覆 相变 Marangoni效应 旋涡 动网格（带讲解和制作视频加参考文章） J你的名字我的姓氏 … thinkpad e480 拆机WebIt seems that in Comsol the Marangoni effect can only be added through Mutliphysics Coupling-> boundary IF you added laminar flow and heat transfer in fluid.
