Cooling and Solidification of Metal
Model ID: 12701
This example is a model of a continuous casting process. Liquid metal is poured into a mold of uniform cross section. The outside of the mold is cooled and the metal solidifies as it flows through. When the metal leaves the mold, it is completely solidified on the outside, but still liquid inside. The metal will continue to cool and eventually solidify completely, at which point it can be cut into sections. This model is simplified somewhat by not computing the flow field of the liquid metal, it is assumed that the velocity of the metal is constant throughout. The phase transition from molten to solid state is modeled via a temperature dependent specific heat. Issues of convergence and mesh refinement are addressed for this highly nonlinear model.
