Effects of gravity on columnar dendritic growth of metallic alloys: flow pattern and mass transfer

Simple rules are proposed for the prediction of segregation effects due to natural convection in the mushy zone during directional solidification in the columnar dendritic regime. The study is based on a scaling analysis of the mass and solute transport coupled with an interpretation of the results...
