Research on Simplified Reverse Method for Interfacial Heat Transfer Coefficient (IHTC)

Abstract:

The success of numerical simulation of solidification process depends to a large extent on boundary condition. Interfacial heat transfer coefficient (IHTC) can be used to measure heat resistance between casting and mold. Boundary condition of casting and mold varies with the temperatures during solidification process. However, determination of heat exchange on the boundary is very complicated. A new simple reverse method has been introduced in this paper. A casting with simple geometry acts as the standard sample and a thermal couple records the temperature history at the center of the casting during solidification. The solidification simulation of the casting was conducted with different IHTCs. The equivalent IHTC that best fits the measured temperature can be determined by comparing the measured cooling curve with the calculated one.
