Abstract
The present work aims to investigate the heat transfer characteristics of heated cylindrical pins within an air-filled rectangular enclosure experimentally in a natural convection dominated regime. The experiments are performed to analyze the effects of fin spacing (25 mm ≤ S ≤ 100 mm) and Rayleigh number (248,659 ≤ Ra ≤ 578,395) as key factors at constant pin height (l = 25 mm) and pin diameter (d = 10 mm) values. The results confirm the existence of optimum fin spacing providing maximum heat transfer enhancement. The investigation is extended further to quantify the effects of the presence of cylindrical porous pins with the uniform diameter (dp = 15 mm), pin length (lp = 20 mm) and calculated porosity of 19.3% by volume on the thermal performance of the system. The results reveal the improved system performance due to the presence of a porous medium for all tested system configurations. Some new empirical correlations predicting system performance are also proposed those demonstrate the satisfactory qualitative behavior of system performance.
