TL;DR: In this article, it was shown that the welding parameters and material properties responsible for the formation of unusual, wavy fusion boundaries can be identified from heat and fluid flow calculations and confirmed by independent experiments.

TL;DR: In this paper, a series of three-dimensional numerical simulations are carried out in a wide range of Marangoni number for a sessile droplet on heated substrate, and the critical cell number of the steady Benard-Marangoni convection keeps on only one for contact angle less than 15 degrees whereas it increases sharply after angle lager than 15°.

TL;DR: In this article, an investigation for magnetohydrodynamics (MHD) thermocapillary Marangoni convection heat transfer of an electrically conducting power-law fluid driven by temperature gradient is presented.
Abstract: This paper presents an investigation for magnetohydrodynamics (MHD) thermocapillary Marangoni convection heat transfer of an electrically conducting power-law fluid driven by temperature gradient. The surface tension is assumed to vary linearly with temperature and the effects of power-law viscosity on temperature fields are taken into account by modified Fourier law for power-law fluids (proposed by Pop). The governing partial differential equations are converted into ordinary differential equations and numerical solutions are presented. The effects of the Hartmann number, the power-law index and the Marangoni number on the velocity and temperature fields are discussed and analyzed in detail.

TL;DR: In this paper, a wide range of values of the Marangoni number, Ma, is considered for the low Prandtl number fluid (Pr = 0.01 ) with the aspect ratio (A = height/length) fixed to be 0.5.

TL;DR: In this paper, the authors used the constructed metal laser direct deposition (MLDD) numerical model to analyze the internal convection morphology of the molten pool, and the results showed that the Marangoni movement is the main factor in the formation of cladding layers.
