In this study, natural convection from vertical cylinders with triangular fins was experimentally investigated with various fin numbers, fin heights, and base temperatures. From the experimental data, we propose a correlation for estimating the Nusselt number, which is applicable when the Rayleigh number, ratio of the fin height to fin length, and fin number are in the ranges of 1000-120,000, 0.2-0.6, and 9-72, respectively. Using this correlation, a contour map depicting the thermal resistance as a function of the fin number and fin thickness is presented. This contour map shows the existence of the fin number and fin thickness, at which the thermal resistance is minimized.
