A simplified thermal approximation method to include the effects of Marangoni convection in the melt pools of processes that involve moving point heat sources

open access: yesNumerical Heat Transfer, Part A Applications, 2021
Processes that use moving point heat sources to temporarily create localized melt pools (metal additive manufacture and fusion welding) have a flow phenomenon due to the surface tension gradient.

Laser Induced Aggregation of Light Absorbing Particles by Marangoni Convection

open access: yesApplied Sciences, 2020
Laser induced Marangoni convection can be used to accumulate micro-particles. In this paper, a method is developed to control and accumulate the light absorbing particles dispersed in a thin solution layer. The particles are irradiated by a focused laser

Microscale engine swimming underwater powered by Marangoni convection

open access: yesJournal of Thermal Science and Technology, 2016
This study proposes a prototype of a microscale engine swimming underwater powered by Marangoni convection. The engine is a layered disk with a hole and holds a bubble ring in a gap between the layers.

Marginal Stability of Oscillatory Bénard-Marangoni Convection With Internal Heat Generation

open access: yesJournal of Computing Research and Innovation, 2023
The onset of oscillatory Benard-Marangoni convection in a horizontal fluid layer with internal heat generation and a deformable free surface is studied using an analytical technique employing the classical linear stability theory.

Marangoni liquid film scattering over an extending cylinder

open access: yesTheoretical and Applied Mechanics Letters, 2019
The impact of the Marangoni convection over the thin film flow on an expanding cylinder has been examined in this study. The diverse effect of the embedded constraints has been detected during the liquid film flow.

Interfacial phenomena between molten iron and molten slag–Effect of nitrogen on the Marangoni convection

open access: yesJournal of Materials Science, 2021
In order to investigate the influence of the surface-active element on the interfacial phenomena between molten iron and molten Al2O3-CaO-SiO2 slag, a mildly surface-active element, nitrogen, was introduced, and the interfacial phenomena were directly ...

Effects of Magnetic Field and Nonlinear Temperature Profile on Marangoni Convection in Micropolar Fluid

open access: yesDifferential Equations and Nonlinear Mechanics, 2009
The combined effects of a uniform vertical magnetic field and a nonuniform basic temperature profile on the onset of steady Marangoni convection in a horizontal layer of micropolar fluid are studied.
