Abstract:Based on the entropy production minimization approach for heat exchanger optimization design and relationship between the entropy production uniformity and heat exchanger performance by Tondeur and Kvaalen,an entropy production uniformity factor is defined and used to optimize Double-chevron Plate Heat Exchangers(DPHE) with different β(corrugation angles).Optimized results based on the entropy production uniformity Criteria and the Performance Evaluation Criteria show that the performance of DPHE with β=30° and β=70° are the best.The Be(irreversibility distribution ratio) decrease as Re and β increase.
