The mathematical model is valid in the solid, mushy (solid + liquid) and liquid regions. A hybrid flow model is employed for the mushy region. This model assumes the mushy region behaves as a non-Newtonian fluid below a transitional solid fraction and as a porous medium thereafter. The positive and negative segregations formed during the solidification are successfully predicted.eninfo:eu-repo/semantics/closedAccessArticle8321823110.1106/JKJ1-4G42-0MDF-PT7A2-s2.0-0033639347N/AWOS:000167625700002Q4
