Summary

RADIATIVE HEAT LOSS CAN BE ATTRIBUTED TO THE SELECTIVE SURFACE TREATMENT, BUT LOSSES BY CONDUCTION AND CONVECTION ARE REALLY A HEAT TRANSFER PROBLEM. DUE TO VERY COMPLEX PHENOMENA, ADEQUATE INFORMATION IS NOT ALWAYS AVAILABLE FOR DESIGNING A SOLAR COLLECTOR HAVING SUITABLE DIMENSIONS FROM THE VIEWPOINT OF LESS HEAT LOSS. THE PURPOSE OF THIS RESEARCH IS TO SUPPLY FURTHER INFORMATION ON FREE-CONVECTION HEAT TRANSFER ACROSS ENCLOSED AND INCLINED AIR LAYERS, INCLUDING HORIZONTAL AND VERTICAL ATTITUDES. EXPERIMENTS WERE CARRIED OUT USING APPARATUS RESEMBLING A PLATE-TYPE SOLAR COLLECTOR WHOSE ABSORBER PLATE IS HEATED BY AN ELECTRIC HEATER. THE RESULTS WERE COMPARED TO THEORETICAL VALUES.
