NSYS MODELLING AND SIMULATION OF TEMPERATURE DISTRIBUTION IN SAND CASTING

Abstract

olidification of molten metal is s very complex phenomenon and many stages occurs during the casting
process, like metal flow, temperature gradient and heat transfer between the mould and casting part. Thermophysical
properties of the molten metal and mould cavity affect the casting part quality. Heat loss from the casting to the mould
then mould walls to the atmosphere plays vital role in the casting process. In the present study two-dimensional
numerical simulation will be carried out utilizing ANSYS software of Aluminium casting in green sand mould.
Aluminium thermophysical properties will be considered temperature dependent while green sand mould thermophysical
properties will be constant. Convective boundary conditions have been considered at the mould cavity walls which
represent the actual physical scenario of the casting process.
