Thermosolutal
WebbImportantly, for an externally applied temperature gradient, the non-uniformities in solute concentration in the present system are solely caused by the Soret effect. This necessitates the consideration of a complete thermosolutal model to study the … WebbThe oscillating droplet method using electromagnetic levitation is a superior way for measuring the surface tension of molten materials, especially for reactive and refractory melts. Through frequency analysis of droplet motions, oscillation frequency is obtained and Rayleigh’s theory is applied to determine the surface tension.

Webb8 sep. 2013 · Hellawell proposed that the solute enrichment and thermosolutal convection produced during solidification have a direct effect on secondary dendrite arms at their roots, which detaches them by melting off rather than breaking off [13, 14], thus yielding grain multiplication, schematically illustrated in Figure 3 . WebbAl-Mudhaf and Chamkha [16] obtained the numerical solution for magnetohydrodynamic thermosolutal Marangoni convection over a flat surface with heat generation or absorption effects. Zhang et al. [17-19] studied Marangoni convection of Newtonian and non-Newtonian power law fluids with coupled boundary conditions.

The two-temperature model of local thermal nonequilibrium (LTNE) is utilized to investigate a weakly nonlinear stability of thermosolutal convection in an Oldroyd-B fluid-saturated anisotropic porous layer. The anisotropies in permeability, thermal conductivities of the porous medium, and solutal diffusivity are accounted for by …
