IV. The Morphology of Natural Convection in Horizontal Liquid Layers. 105... [Pg.61]

Since the Constitutional Supercooling Criterion [1] and the analysis of Nullins and Sekerka [2] the study of the morphological stability of a planar solidification front during unidirectional growth of a binary alloy has been extensively developed [3]. Most of the authors consider that the melt is motionless so that heat and matter are transported by diffusion only. Convection in the melt can yet be actually important [4,5]. The influence of natural convection has recently been taken into account for a viscous liquid phase [6,7],... [Pg.263]

We analyse natural convection for some viscoelastic rheological behaviors for the melt and then Marangoni convection. A prospective investigation is achieved so as to bring out new effects on the limit of morphological stability of a plane solid-melt interface. [Pg.263]

The present model approach has combined three equations to predict the onset of cellular growth during freezing of natural waters (i) constitutional supercooling from morphological stability theory, (ii) an exact diffusive solute redistribution and (iii) an intermittent turbulent solutal convection model. The main results are ... [Pg.388]
