Abstract
AbstractIn this paper, we determine the trends and weights of the structural parameters on the heat transfer, flow resistance and comprehensive performance of high pressure direction (HPD)‐type perforated fins using Taguchi method and analysis of variance (ANOVA). The findings underscore the fin height as the most pivotal element affecting comprehensive performance, with its contribution ratio of 42.2%. Ultimately, the highest j‐factor, the lowest f‐factor, and the maximum JF‐factor were obtained as the objective functions, yielding the three most optimal sets of parameters. The findings reveal a remarkable 89.7% reduction in the f‐factor of the optimized HPD‐type perforated fins, accompanied by a substantial 127% augmentation in the JF‐factor compared to the HPD‐type fins.
