Numerical simulation of solidification and structure formation of the metallic ingot

A three-dimensional viscous fluid flow with the convection and phase transfer is considered. Mathematical models of the filling and solidification processes in a steel ingot and their discrete analogs are developed. A coupled hydrodynamic and thermal problem is solved numerically by the software ProCAST 2010.0 based on a finite-element method. The distribution of the shrinkage porosity in the ingot's body is received and the influence of the natural convection during the solidification process on the final ingot's structure is discussed. The prediction of macrostructure formation is made.
