Abstract
The objective of this study is to investigate the natural convection heat transfer from air-cooled finned tubes on a horizontal cylinder. For the CFD simulations, surrounding air temperature is varied from 22ºC to 33ºC for fin bases temperature from 8ºC to 15ºC. Heat transfer rates from fin interfaces and tube base are calculated through the simulations, and good agreement is observed. The effects of fin diameter and ambient to surface temperature difference on the heat transfer have been investigated. The effectiveness of the fins was also evaluated for all the CFD simulations.
