Abstract: The latest progress on the study of numerical simulation of
mold-filling and solidification process of shaped casting is
reviewed. In mold-filling process simulation of castings, the
SOLA-VOF algorithmis is improved in efficient free surface
treatment and turbulence consideration, and parallel
computational techniques are implemented to accelerate the fluid
flow calculation time as well. Methods for predication of
shrinkage defects of steel castings and S. G. iron castings are
developed based on the solidification simulation. In order to
reduce the residual stress and deformation of castings, a
combined FDM/FEM method is implemented for the modelling of
stresses. Numerical models for the simulation of microstructure
and predication of mechanical properties of S. G. iron are
developed. The verifications and applications of the simulation
software show that the models and techniques adopted in current
research work are efficient and appropriate for numerical
simulation of shaped castings.
