摘要

This work introduces a two-dimensional numerical model for the coupled solution of momentum, energy and turbulence equations, especially addressed to binary alloys solidification. The governing equations consist of the continuity equation, the Navier–Stokes equations and the energy equation. The turbulence effects on the transport equations were taken into account using a low-Reynolds number k-ε turbulence model. The solidification of molten steel was modeled through the implementation of the enthalpy-porosity technique. The effect of phase change on convection is accounted for using a Darcy's law-type porous media treatment. The resolution of those equations has been implemented in FLUENT code. Finally, we show an application of the model to the solidification in a steel continuous casting. The current study shows that casting speed is a very important parameter in controlling the breakout condition of the cast material.
