... thermocapillary mell flow simulation Surface tension in liquid metals is one of the important physicochemical properties in understanding various interfacial phenomena. Moreover, it has been well established that the surface tension force (Marangoni flow) in gas tungsten arc (GTA) welding is identified...

...Nancy Ma; John S. Walker; Laurent Martin Witkowski This paper presents a linear stability analysis for the thermocapillary convection in a liquid bridge bounded by two planar liquid-solid interfaces at the same temperature and by a cylindrical free surface with an axisymmetric heat input. The two...

...David M. Pratt; Kenneth D. Kihm An investigation has been conducted into the interactions of binary fluid mixtures (pentane [ C 5 H 12 ] coolant and decane [ C 10 H 22 ] additive) and thermocapillary effects on a heated, evaporating meniscus formed in a vertical capillary pore system...

... concentrations, and wall heat flux levels are represented by a range of thermocapillary and diffusocapillary Marangoni numbers ( 6 ⩽ Ma T ⩽ 10 3 , 0 ⩽ Ma S ⩽ 8.6 × 10 5 ) over a micro-scale time period (1 μs–1 ms). With a surfactant in solution, a surface concentration gradient develops at the bubble interface...

...Y. Jiang and; J. M. Floryan Thermocapillary convection in a cavity is considered. It is shown that when the cavity is heated through its sides, reduction of heat transfer across the interface leads to an increase of the interface deformation. When the same cavity is heated through the interface...

... as a result of the thermocapillary convection in the droplet and it determines the effect of fluid motion on the heat transfer between the drop and the solid surface. This study is particularly relevant because the internal fluid motion has not been considered in previous numerical and analytical models...

... Convection Surface Tension Thermocapillary Consider a quiescent liquid layer heated from below that is bounded from above by a passive gas. A sufficiently strong heating leads to instability. The instability motion can be a result of either the Marangoni effect associated with the temperature...

.... This liquid flow caused by the temperature gradient along the interface is called thermocapillary or thermal Marangoni convection. The studies were made with silicone oils of different viscosities so that a wide range of dimensionless numbers were encountered. The velocity fields are determined from...

...Y. Kamotani; S. Ostrach Steady and oscillatory thermocapillary flows of high Prandtl number fluids in the half-zone configuration are analyzed theoretically. Scaling analysis is performed to determine the velocity and length scales of the basic steady flow. The predicted scaling laws agree well...
