Shear-enhanced convection in a mushy layer

Abstract:

We investigate the effect of an external shear flow on the buoyant instabilities inherent in the directional solidification of a dendritic mushy layer. In the presence of an external shear flow, perturbations of the mush-liquid interface lead to perturbed flow in the bulk fluid that create pressure variations along the mush-liquid interface. These pressure variations drive flow in the mushy layer. A numerical analysis of the stability of the system provides the critical porous-medium Rayleigh...
