Originální abstrakt

This article describes methods used for obtaining both the thermal contact resistance (TCR) between an alloy casting and the mold, and the heat transfer coefficient (HTC) between the mold and a bath that is used to control the speed of the solidification process. Both the Downhill Simplex optimization method and Beck's approach are used in the inverse task. These inverse tasks, which simultaneously compute both the TCR and HTC, use a model involving a phase change during the solidification of the alloy. An automatically generated mesh uses the control volume method and "Direct Enthalpy" algorithm instead of the "Total Enthalpy" approach to compute the temperature profile inside the alloy-casting model. A comparison of the Downhill Simplex optimization method and Beck's approach is made.
