Since the Annual Review of Fluid Mechanics review of mushy layers by, there have been
significant advances in the understanding of convective processes in mushy layers. These …

Single-crystal nickel-based superalloys are used for turbine blades in jet engines and power
generators. During the solidification of these alloys, misoriented defects, namely freckles …

Convective instabilities responsible for misoriented grains in directionally solidified turbine
airfoils are produced by variations in liquid–metal density with composition and temperature …

Fluid flow within the dendritic structure at the solid–liquid interface in nickel-based
superalloys has been studied in two directionally solidified alloy systems. Millimeter-scale …

Unidirectional ice-templating produces materials with aligned, elongated pores via:(i)
directional solidification of particle suspensions wherein suspended particles are rejected …

We report theoretical and experimental investigations of the flow instability responsible for
mushy-layer convection with chimneys, drainage channels devoid of solid, during steady …

We consider a model for the solidification of an ideal ternary alloy in a mushy layer that
incorporates the effects of thermal and solutal diffusion, convection and solidification. Our …

Convective flow within the mushy zone of directionally solidified superalloys can result in the
formation of freckles and misoriented grains. These defects signal not only a disruption in …

In the examples of forced and natural convection discussed until now, the fluid that flowed
through the pores did not experience a change of phase, no matter how intense the heating …
