On the Accuracy of Inverse Evaluating Heat Transfer Coefficient

Abstract:

Together with Finite Difference Method, The sequential function method set up a mathematical model for inverse heat transfer problem, solving interface heat transfer coefficient for water cooled metal. Discussion on results indicates that the selection of time step throw striking influence on the evaluation accuracy, especially when the surface heat transfer coefficient experiences a drastic variation. A proper value of time step is confirmed to be 0.01s, where lies comparatively an acceptable error, being 0.37%.
