| Abstract: | Based on determining the infrared properties of single laye of materials, this paper establishs the appropriate physical models for the radiative heat transfer in honeycomb structure and presents procedures computing the infrared radiative loss decrease coefficient of the absorber plate with Mente Careo algorithm. The effect of the honeycomb aspect ratio and the infrared properties of materials on the decrease coefficient is discussed. The results predicted compare well with the experimental results and provide good information for the design and optimization of honeycomb structure collectors |
