OPTIMUM LONGITUDINAL CONVECTIVE FIN ARRAYS

摘要

This study presents the optimum design for longitudinal fin arrays in forced convection. Rectangular, convex-parabolic-profile, triangular, and concave-parabolic-profile fins are taken into consideration in the analysis. The aspect ratio, interfin spacing, and heat transfer characteristics of the optimized fin arrays are investigated with a given geometry of base plate, fin area, and constant thermal properties. A comparison in the total heat duties as well as the efficiencies of the four different arrays is also made. The results of this work are presented in dimensionless form for the convenience of parametric study and design analysis. [References: 16]
