In this paper, in order to analyze and evaluate the comprehensive thermodynamic performance of heat transfer enhancement in tube, an method which based on the entropy generation analysis for process is developed. Then the expression is applied to analyze different kind heat transfer enhancement in tube. The analysis results show that the method is a simple and valuable united method, which not only can be used to analyze and evaluate the comprehensive thermodynamic effect of different kind heat transfer enhancement element, but also can be used to determine the suitable flow working condition and structure parameters and heat transfer enhancement form. Figs 7 and refs 6.
