dc.description.abstractIn this study, the solidification of a generic binary alloy in a two-dimensional cavity is numerically investigated. The mushy region that is formed during solidification is considered a non-Newtonian fluid, then a critical solid fraction and a porous medium thereafter. An internal variable which represents the agglomeration and disagglomeration of grains is used in the model. The solidification problem is also solved using a porous model, which is employed generally in the literature and the results are compared with those obtained with the new model. The new model is found to predict an irregular interface morphology between the mushy region and the liquid region.
