Experimental Study of Natural Convection from an Array of Square Fins
In this research, we experimentally investigate natural convection heat transfer of three finned-tube exchangers with an array of square fins and a fin spacing of 5, 9, and 14 mm. The exchangers are in a 5.8m x 4m x 3m control room where temperature and humidity are automatically controlled with heating, cooling, humidifying, and dehumidifying equipment. We changed the surface temperature of the center tube by varying the input power of the heating element from 8.4 to 56.7 Watts.
