Modeling of melt pool thermal behavior in laser material
… interaction, such as phase changes and the Marangoni effect. Since the melt pool dynamics is primarily driven by the interfacial forces, which in turn rely considerably on the melt pool geometry, a free surface tracking method associated with the numerical implementation scheme is proposed. …

Derivation of an Evolution Equation for Two-Dimensional Waves on Thin Films
… to gravity, fluid friction, surface tension, and Marangoni effects. The physical configuration is a thin liquid layer on a planar incline. Following previous studies, the Marangoni effect is incorporated by a constant surface tension gradient and yields a non-convex flux function in our thin film …

Oxidation kinetics of molten copper sulphide
… from 20-78% 02, was conducted to determine the effect of oxygen concentration on the kinetics of the oxidation reaction. To determine the influence of volumetric gas flow rate on the kinetics of the oxidation reaction and to study the gas phase mass transfer, a series of laboratory tests was …

Heat transfer analysis of thermoelectric driven swirling flow
… the experiment which was firstly believed to be Marangoni effect. To reveal the truth of this flow the Solid/Liquid Lithium Divertor Experiment (SLiDE) was constructed at University of Illinois, Center for Plasma-Material Interactions. SLiDE has similar experimental conditions as CDX-U and in …

Mechanisms of focused ion beam (FIB) material removal and rearrangement at high beam flux
… and describe the role of explosive boiling and Marangoni effect as a material removal and rearrangement mechanism and the mixing and transport that occur at the atomic scale. Nanopore fabrication using FIB is typically understood to occur via sputter erosion. While this theory may describe …

Instabilities of volatile films and drops
… This model includes all relevant physical effects, including evaporation, thermal conductivity in both liquid and solid, (thermocapillary) Marangoni effect, vapor recoil, disjoining pressure, and gravity. The crucial ingredient in this problem is the evaporation model, since it influences …

Laserstrahltiefschweißen hochfester Feinkornbaustähle in der Serienproduktion
In der serienmäßigen Verarbeitung von hochfesten Feinkornbaustählen zeigte sich, dass verschiedene Stähle gleicher Festigkeitsklasse zu stark unterschiedlichen Schweißergebnissen beim Laserstrahltiefschweißprozess führen können. Die materialbedingten Einflüsse auf das Schmelzbadverhalten sind …
