Abstract:Using the inverse algorithm of heat transfer and the nonlinear estimation method, matching calculated values with measured ones, the interfacial heat transfer coefficient at casting/Cu mould interface was determined.The results show that the interfacial heat transfer coefficient at Al/Cu interface changes in a range of 4.0×103-1.0×105W·m-2·K-1 and its average value is in a range of 5.0×103-7.0×103W·m-2·K-1.

 

Key words: interfacial heat transfer coefficient; inverse problem; nonlinear estimation method
