A huo-dimenswnol -rim1modeling study was undertaken to account for coupled turbulent Jbw and hent transfer with solidijiurtrurtron in the mold and submold regr'ons of a steel slab caster. Liquid steel is inlmdued in& a waier-ewled mold through a bifiucated submerged entry Mule. Turbulence p h e m m e~ in the meU pool of the cactcr were accounted for, using a modified version of the low-Reymldr-number k-e turbulence model of Lounder and Sharma. nK mushy region solidificcrtion, in the presence of turbulence, was taken into account by modifying the standard enthalpy-porosity technique, which is present& popular for modeling solidijiention problems. nK~~ermrrurpiUary and buoyancy effects / w e been considered in this model to evaluate the influrnces of the liquid &ace tension gradient at the meniscus sudace, ond Mhuol convection on Jlow pattern in the liquid pool. Pammehic studies were urrried out to evaluate the effea3 of typiul variables, such as i& superheat and m ' n g speed, an the m i d Jlow ond heat rronfer &. llw numen'cnl predictr'ons were compared with auoiloble erpcrimntal &a.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
