Prediction of solidification time of cylindrical hollow casting cast in Co₂-sand moulds by using fem technique

Prediction of solidification time is one of the very important parameters used for assessing the properties of the material. In the present study, experimental investigation is carried out to measure the solidification time in a cylindrical hollow casting cast in CO₂-Sand moulds and the same has been compared with the Analysis made through finite element method Technique. Finite Element Analysis was carried out by using ANSYS FEM Package. Standard physical properties were taken from ASTM metal handbook. Latent heat evolution was incorporated by enthalpy method. The solidification problem for hollow cylindrical casting was assumed to be a 2-Dimensional transient Heat Conduction flow. Convective Heat losses were considered. Aluminum-4.5% copper alloy has been used. The experimental and FEM results are compared and found to be in good Agreement.
