abstract = "In order to improve the accuracy of the numerical simulation, an inverse methodology of evaluating the IHTC (interfacial heat transfer coefficient) is proposed for a complicated blade casting by combining the FEM simulation, optimization method and measured temperature data of the casting and the shell mould which are gained by an investment experiment of the blade undertaken elaborately. Regarding the complicated mechanism of the air gap in the progressive solidification, a continuous IHTC model of three-step evolution is originally established, and such a parameterized model is particularly beneficial in improving the efficiency of the optimization. Results show that the predicted temperatures based on this model agree well with the experimental temperatures and the maximum deviation is less than 5.2\% at six specific measured locations.",
