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.
