碩士 / 國立成功大學 / 系統及船舶機電工程學系碩博士班 / 92 / The local time-dependent surface heat transfer coefficients for plate finned-tube heat exchangers are determined in a three-dimensional inverse heat conduction problem. The inverse algorithm utilizing the Steepest Descent Method (SDM) and a general purpose commercial code CFX4.4 is applied successfully in this study in accordance with the simulated measured temperature distributions on fin surface by infrared thermography. Two different heat transfer coefficients for staggered as well as in-line tube arrangements with different measurement errors are to be estimated. Results of numerical simulation show that the reliable estimated heat transfer coefficients can be obtain by using this inverse algorithm.
