Experimental study of the heat transfer and air gap evolution during casting of an AC4CH Aluminum alloy
Keywords:aluminum casting, heat transfer and air gap, numerical prediction
In the context of rapid changes of the technologies, casting becomes a manufacturing process of an increasing use. Therefore, the numerical methods and algorithms for solving heat conduction problems were extensively developed during the last 10 years. Based on finite element techniques, these algorithms provide an accurate analysis of heat transfer. This paper presents the numerical and experimental results of heat transfer coefficients determination, at the cast/core and cast/mold interfaces, during solidification and cooling of a hollow cylinder cast part made of Al-7%Si-Mg alloy (AC4CH)
