碩士 / 國立成功大學 / 機械工程學系 / 85 / The heat transfer coefficient of the plate finned-tube heat exchanger is searched mainly in this thesis. Since the field of fluid that flows across fins is very complex. The previous scholars is to simplify the complexity of the problem so as to be the constant for the heat transfer coefficient of the fluid. In fact, the heat transfer coefficient should be the function of location. We will tell the difference from the heat transfer coefficient as to be the function of location to it as to be the constant and say some heat transfer phenomenon in the fins in this thesis.
In addition, the fin efficiency and the fin heat transfer coefficient are predicted by the scheme of inverse heat conduction in the thesis. The main purpose of that is that we want to estimate the heat transfer coefficient with the information of fin temperature measured by thermocouple. because the prediction of the heat transfer coefficient if exactly or not is influence on the fin efficiency deeply, so the results for the method of inverse is used to comparison by the fin efficiency.
Finally, it should be mentioned that most of previous scholars tried to determine the heat transfer coefficient of the flow fluid straightforwards and subsequently the fin efficiency. The inverse method of this thesis need only to measure the fin temperature and can predict fin efficiency. Thus, the present method is very powerful.
