Summary

In this study, the inverse heat transfer method was applied to shape identification for the ice layer within the cylindrical capsule in cold storage system. The approach was constructed by combining the curvilinear grid generation scheme, the direct problem solver, the conjugate gradient optimization method, and the redistribution method. According to the practical condition of freezing ice, shape identification for the water-ice interface based on the data of the outer surface temperature was attempted. Results showed that the profile of the water-ice interface could be identified by using the inverse heat transfer approach and the accuracy of the ice shape identification was dependent on the uncertainty of the outer surface temperature data, the Biot number, the thickness of the ice layer, and the geometric configuration.
