Numerical modeling in the casting process has become a key tool for predicting defects and optimizing processes. The interfacial heat transfer coefficient is one of the important boundary conditions in casting numerical modeling, which is difficult to be obtained by direct measurement and is often determined through inverse calulation technique. The inverse calulation technique have characteristics such as nonlinearity, large computational requirements and non-unique solutions, which increase the difficulty of inverse solution. This work reviews the current research status and latest developments of the interfacial heat transfer coefficient inverse calulation technique in casting numerical modeling, summarizes the main inverse solution methods of the interfacial heat transfer coefficient, and elaborates on the impact of the inverse algorithm-based interfacial heat transfer coefficient in numerical modeling of the casting process. The limitations and shortcomings of the existing inverse calulation technique are discussed, and future research directions and technological development trends are proposed.
