Abstract:

Solidification time is an important parameter used to assess the properties of cast materials. In the present study, experimental measurements of the solidification time in cylindrical hollow CO₂–sand castings has been compared with predicted values from finite element modelling. Finite element analysis was carried out with an ANSYS package using standard physical properties. Latent heat evolution was incorporated by the enthalpy method. The solidification for the hollow cylindrical casting was assumed to be a two-dimensional transient heat conduction flow problem. Convective heat losses were considered. Experimental results for a Al–4.5Cu alloy compare well with the solidification times predicted by FEM analysis.
