OpenFOAMを用いた熱交換器の流体・伝熱連成解析

抄録

Heat exchangers are widely used in various industrial fields, but the behavior of the thermal fluid inside is complex, and there are problems of performance degradation due to pressure loss and stagnation. In this study, we attempted to predict the heat transfer performance of a finned-tube heat exchanger with fins inclined at 45 degrees to the tubes by analysis. The analysis was performed using OpenFOAM's chtMultiRegionFoam to verify the accuracy of the analysis and to investigate convection and pressure loss by comparing the experimental and analytical results.
