Control-Volume Finite Element Analysis of Phase Change During Direct Chill Casting

摘要

A fully implicit control-volume finite element method is used to analyze the phase change during DC casting of aluminum alloy. The mathematical model is based on the integral form of the en- thalpy equation. A Eulerian-Lagrangian transformation, together With a deforming grid technique, is introduced to efficiently track The evolution of the physical domain. The temperature distribution Predicted by the numerical model is in good agreement with that Measured in previous experiments.
