Spectrum analysis and gray prediction of the micro combustor

The radiation spectrum and gray prediction of the micro combustor materials is studied in this research, The results prove that: during a certain temperature range using appropriate radiation materials can improve the photoelectric conversion efficiency; using porous media environment is better than that without at the high and uniform temperature distribution along the outside wall; the introduction of the gray system theory is provided an effective method for the study of the micro combustor performance analysis, this paper mainly direct at the working temperature range of AL₂O₃ ceramics which has carried on the predictive analysis and achieved better results.
