Abstract


In recent years, micro-electromechanical systems (MEMS) applications increasingly widespread energy source development has become its biggest obstacle . Therefore, the development of high power density , micro - power system has strong practical significance . As one of them, the miniature thermal photovoltaic systems due to the presence of the many advantages gradually become one of the hot . The object of this paper is the use of flat - burning ( radiation) of the miniature thermal photovoltaic systems . Burner is the core component of the system and the energy source , the course of their work will directly affect the energy conversion efficiency of the entire system . The combination of numerical and experimental methods to study it , the view factor of its internal combustion heat transfer process of law, to seek an effective way to optimize its performance . With simulation burner work for qualitative analysis . We have established a burner combustion heat transfer calculation model , simulated under the conditions such as the type of porosity , the inlet flow rate and the volume mixing ratio of the burner wall temperature and the internal flow field and the component field distribution . The calculation results show that : the rational and select the structure and condition parameter can improve the performance of the burner ; under the same conditions , the presence of long and short medium enables the burner to obtain a more uniform distribution of the wall surface temperature and a lower outlet temperature . The experiment is used to verify the accuracy of the calculation . , Calculated by reference to the prediction results , can be more effectively carried out a quantitative study . The experimental part of flatbed burner tube-type burner for a simple comparative experiments . The burner wall and the outlet temperature distribution is the external reflection of the internal combustion heat transfer process , its temperature distribution through the observation of changes in the structure and working parameters can be drawn from the impact of the law of the relevant factors on the performance . Burner wall surface of the thermal radiation intensity PV wafer sensor. The experimental results show that : the change of the shape of the burner structure their work performance . Select the appropriate structure and working parameters and radiation characteristics and low energy bandgap photovoltaic cell absorption spectrum that matches the wall radioactive materials can be optimized burner wall temperature distribution , and thus enhance the performance of the entire system with strong selective thermal photoelectric conversion efficiency .
