On Heat Transfer Correlation of Vertical Parallel Plates in Free Convection

Abstract

Natural convection heat transfer from vertical parallel plates was investigated experimentally. A set of nine different parallel plate sizes were tested. Square parallel plates with sides of 100 mm, 150 mm and 200 mm were used to examine the convection heat transfer rate for plate separation distance of 10 mm, 30 mm and 50 mm respectively. Power inputs were supplied to each arrangement in order to generate temperature difference between the plates The results of this study have shown that the convective heat dissipation rate from these vertical parallel plates depends on geometric parameters, temperature excess and as well as separation distances between the plates. A new correlation has been presented on the basis of the experimental conditions of this study. These correlation equations were compared with some established data.  Results seem to correlate in some sense most previous work.
