Fluidity of ADC12 Alloy Based On Theoretical and Computational Fluid Dynamics

Fluidity is one of the important factors that play a role in the casting industry. The current paper focuses on understanding the fluidity behavior of the aluminium alloy ADC12 in a spiral shaped mold based on the theoretical and simulation results. The aluminium alloy is subjected to the heating temperature of 670 c along with the die preheated to a temperature of 200 c and is poured into the cavity as gravity die cast. This enables the molten metal to travel a certain distance till it reaches the solidus temperature and get solidified. The maximum distance the alloy travels ensures the fluidity of the aluminium alloy. This paper gives a comparison between the theoretical fluid dynamics value and the computational fluid dynamics value for validating the fluidity of the aluminium alloy. The entire process is done on the theoretical formulas and the simulation process is done using the ANSYS simulation software. The spiral test shows how a modeling approach will predict fluidity index, mold filling, fluid temperature and the distance travelled for a given spiral and complex shaped casting.
