Abstract

A series of experiments has been carried out to determine the influence of fin parameters upon natural convection from a finned horizontal cylindrical heater. Due to its numerous applications, the fin geometry is chosen to be circular. The test section is constructed from a central heating tube, aluminium collars, and copper fins. Therefore, the experimental set-up is capable of analysing the effect of the fin diameter and spacing on heat transfer. In respect to the experimental results, the effect of gamma, the ratio between fin space and body diameter, within the range studied (0.25 less-than-or-equal-to gamma less-than-or-equal-to 1.5), appears to be indiscernible on natural convection. However, the lambda-effect, the ratio between diameter of fin and cylindrical body, has been considered in the stated correlations.
