HEAT TRANSFER CHARACTERISTICS OF THE SOLAR CHEMICAL REACTOR WITH THE FILLS AND THE VOLUME FLOW RATES
The heat transfer characteristics of solar chemical reactors are experimentally investigated. The heat transfer characteristics become different according to solar chemical reactors fills and volume flow rates of working fluid. The experimental apparatus is fabricated to satisfy the matters which are referred above. Experimental equipment consists of a solar chemical reactor, an electric heater, a blower, a flow meter, a flow distributor, and thermocouples. The solar chemical reactor, which is the test section for the experiment, is fabricated. It is a cylindrical cavity-receiver of the height 180 mm, and the inside diameter 100 mm. The fills, which is inserted in the solar chemical reactor, are mesh and porous metal. In order to heat the inside of the reactor, the electric heater is installed. Air temperatures are measured by installing 4 thermocouples on each layer, dividing reactor into 7 layers. The volume flow rates of air are varied from 20 l/min to 40 l/min. To reduce the convection heat transfer, the quartz glass is inserted between reactor and heater. From the experiment, the temperature distributions along the flow direction and the radial direction can be obtained. The results show that best volume flow rate is 30 l/min in this experiments reactor and the difference of temperatures is a little with variation of fills metal.
