SOLIDIFICATION SIMULATION OF Al 6061 CASTING IN 2-D GREEN SAND MOULD
Keywords:Numerical simulation, Conduction heat transfer, Al 6061 and green sand mould
Numerical simulation of Al 6061 in green sand mould has been studied. Two-dimensional heat conduction
equation governs the physical problem. Convective condition has been considered at the interfaces where molten metal
meets the mould cavity surface. Finite difference technique has been adopted to solve the heat conduction equation in
unsteady state and transient state.Central difference scheme for spatial terms and explicit scheme for temporal term have
been adopted to discretize the governing equation. MATLAB package has been used to study the thermal flow and
cooling rate. Green sand as mould cavity material and Al 6061 as molten metal material has been considered.
Temperature distribution of Al 6061in green sand mould for two-dimensional casting for steady problem and cooling
rate of with time have been plotted.
