Marangoni flow in floating half zone of molten tin

Gravity affects the stability of Marangoni flow in floating half zone of low-Pr fluids through two different factors, i.e., the buoyancy and the static deformation of the free surface shape. In the present study, influence of these two factors are evaluated by unsteady three-dimensional (3D) simulations for a realistic model of floating half zone of molten tin (Pr = 0.009) with an aspect ratio As = 2.0 under a ramped temperature difference (1.19...
