Abstract

An engineering approach to modelling turbulent flows in the presence of solidification is presented based upon the widely used low-Reynolds &-e turbulence model. Limitations in the approach are discussed as well as the challenges of incorporating the complexities of the moving solidification front into turbulence models. An industrial example related to near-net-shape continuous casting is analyzed to illustrate the usefulness of the method. 1 Introduction In recent years, the modelling of solid/liquid transport phenomena has received considerable attention across a broad spectrum of materials processing disciplines. As for example numerous modelling efforts can be cited for unidirectional solidification systems where the infl
