Finite difference modeling of solidification of pure aluminum, Al 6063 and brass casting in green sand mould has been simulated. Unsteady heat conduction eq. in two-dimensional form governs the physical problem. Convective boundary conditions have been considered at the interface where molten metal meets the mould cavity surface. Heat conduction eq. in unsteady state and transient state have been solved by using Two dimensional finite analyses difference method using MATLAB to study thermal flow and cooling rate. The properties of materials utilized are green sand and pure Al, Al6063 and brass. The results obtained are: cooling rate of pure Aluminum, Al6063 and brass in green sand mould for 2D casting for unsteady problem and temperature distribution in steady case.
