Reconstruction of the Total Heat Exchange Factor Using the Inverse Heat Conduction Problem

Abstract:

A new inverse algorithm is proposed for the reconstruction of the total heat exchange factor, which is concerned with transient heat conduction problems. The unknown total heat exchange factor is treated as the optimization variable, and the errors to be minimized are the differences between the calculated temperatures and the measured ones. The sensitivity coefficients are obtained by the complex-variable-differentiation method. The effectiveness, efficiency and accuracy of the inverse approach are demonstrated in few test cases.
