Abstract
This paper focuses on investigating and analyzing the effects of geometric parameters on the performance of interrupted flying-wing fins (IFWF). The incorporation of interruptions in the flying-wing fins (FWF) effectively enhances heat transfer efficiency, and increases flow resistance. Moreover, when the number of interruptions exceeds 3, the comprehensive performance of the heat exchanger is diminished. Numerical simulations are employed to thoroughly investigate the effects of geometric parameters individually, within the Reynolds number range of 600–1600, and correlations for the j and f-factor of the IFWF are proposed using the responses surface method. The parametric study of the contribution ratio on the j-factor, f-factor, and JF-factor is obtained by the Taguchi method, including 18 cases with different combinations of key parameters. At a Reynolds number of 1000, it becomes evident that parameter A exerts the most substantial influence on the j-factor, f-factor, and JF-factor. Consequently, in the design of IFWF, prioritizing amplitude A is imperative.
