Equivalent heat transfer coefficient at casting/Cu mould interface and temperature field simulation

摘要

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 X 10~3 - 1.0 X 10~5 W·m~(-2)·K~(-1) and its average value is in a range of 5.0 X 10~3 -7.0 X 10~3 W·m~(-2)·K~(-1).
