This paper describes the development of an evaluation program designed to efficiently assess the performance of heat exchangers, which are crucial in factories and power plants for heat transfer processes. The program’s efficacy was verified by comparing its results with those from the Electric Power Research Institute (EPRI) TR-101397’s Appendices C and F, as well as with examples from EPRI data. For the uncertainty analysis, both the Colburn and Delaware equations were utilized to accurately reflect the heat transfer characteristics of heat exchangers. The results indicate that the program’s results match closely with those from EPRI TR-101397 for three analyzed cases. In addition, the Delaware equation proved more effective than the Colburn equation in the performance evaluation program for ensuring comprehensive uncertainty analysis. The developed program can provide important information necessary for the safe operation and efficient management of safety-related heat exchangers.
