Lumped-Capacity Method for Easy Estimation of Interfacial Heat Transfer Coefficients in Die Casting

Zehui Sun, Guoli Li, Zhe Qian, Weifei Li, and Jian Jing
Abstract—The interfacial heat transfer coefficients (IHTCs) are the key parameters in numerical simulations on casting processes, but the inverse estimation of them from experiments is very difficult to be conducted and involves considerable uncertainty. With the assumptions of isothermal casting and one-dimensional heat conduction, this paper presents a lumped-capacity method for inverse estimation of IHTCs for die casting of high thermal conductivity metals. This method greatly simplifies the procedure of temperature measurements while providing estimation of IHTCs with reasonable accuracy.

Index Terms—Interfacial heat transfer coefficient, high thermal conductivity casting, lumped-capacity method, onedimensional heat conduction model.
