Abstract

This article presents the theoretical and experimental analysis of natural convection heat transfer through heated vertical parallel plates. Two vertical parallel plates are heated by providing electrical heating coils on the external surface of the plates maintaining uniform heat flux conditions at the wall. The length, width and thickness of each plate is 500 mm, 150 mm and 5 mm respectively. Outer surface is insulated and thus allowing the heat to flow from the inner surface to air. Wall heat flux is kept at q// = 2188W/m2. A systematic experimental as well as theoretical data for the steady state heat transfer phenomena is attained. The results of the numerical analysis for air and wall temperatures are compared with that of the experimental investigation for same heat flux conditions. The results of both the investigations were found be in good agreement with each other for heat flux of 2188 W/m2.
