Abstract

Numerical simulation of unsteady state conduction heat transfer has been studied during the solidification of Aluminium casting in green sand mould. Two-dimensional heat conduction equation governs the physical problem and convective boundary condition has been considered at the interface where molten metal meets the mould cavity surface.Two-dimensional finite difference analysis of heat conduction equation in unsteady state (Laplace’s) and transient state have been solved using MATLAB R2012a to study the thermalflow and cooling rate. The properties of materials used are industrial AI 50/60 AFS green sand mould and pure aluminium.The results obtained are:temperature distribution of Aluminium molten metal in green sand mould for 2D casting for steady problem and cooling rate of molten metal with time. The results obtain were consider relevant in the control of the grain size and mechanical properties of the casting.
