Abstract

Heat exchangers are integrated in all process and energy plants. Shell and tube heat exchanger designs are most commonly used. The efficiency and performance of the device can be determined both experimentally and numerically. In this study, a numerical model of heat transfer in a small size shell and tube heat exchanger is presented, and the results are compared with experimental data. The problem with laminar flow and steady state heat transfer was solved using the finite volume method. Three experiments were performed, and all of them showed a high match between outlet fluid temperatures. As additional validation, heat flux balance was set and calculated for both methods, which also showed a considerable match. It can be concluded that the model accurately predicts physical phenomena in analyzed heat exchanger, and can be used in further studies.
