Effects of the mould wall thickness on the solidification and heat transfer have been studied in the present paper. Aluminium in pure form and green sand has been adopted as a molten and mould cavity material respectively. Aluminium thermal properties are considered to be temperature dependent. Casting products have been used in many industries and household applications. Solidification and heat transfer during casting are crucial events which have been focused in the present study. Mechanical APDL has been used to simulate the present problem. 2-D casting of pure aluminium has been done with green sand as a mould cavity material. Heat conduction equation in 2-D form governs the problem in the casting part. At the mould cavity outer walls convective boundary conditions have been adopted. High temperature range has been found with 7200 sec simulation time compared to 3600 sec simulation time. High temperature range has been found for assembly-3 which has large cavity thickness among the considered. Temperature dependent thermal properties can serve better results.Keywords: Mould wall thickness, solidification, thermal properties, CFD, mould cavityCite this ArticleShubhi Yadav, Jitendra Jayant.
