摘 要：正The heat transfer characteristics of solar chemical reactors are experimentally *** heat transfer characteristics become different according to solar chemical reactor’s fills and volume flow rates of working fluid. The experimental apparatus is fabricated to satisfy the matters which are referred *** 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 *** is a cylindrical cavity-receiver of the height 180 mm,and the inside diameter 100 *** fills,which is inserted in the solar chemical reactor,are mesh and porous *** order to heat the inside of the reactor,the electric heater is *** temperatures are measured by installing 4 thermocouples on each layer, dividing reactor into 7 *** volume flow rates of air are varied from 20 l/min to 40 l/*** reduce the convection heat transfer,the quartz glass is inserted between reactor and *** the experiment,the temperature distributions along the flow direction and the radial direction can be *** results show that best volume flow rate is 30 1/min in this experiment’s reactor and the difference of temperatures is a little with variation of fills’ metal.
