چکیده انگلیسی
Over the past decade, the micro-thermophotovoltaic (MTPV) system has aroused widely public attention. Micro-combustor is an important part, which can determine the working performance of this micro-power generator. In this paper, experimental investigations as well as a three-dimensional CFD simulation have been carried out to study the performance of propane/air premixed combustion in a new kind of cross-plate micro-planar combustor. Benefited from the heat transfer enhancement by the setting up of cross-plate, the average wall temperature of the new combustor is increased by more than 90â¯K, which results in the growth of radiation efficiency. Besides, the blowout limit is apparently extended in the cross-plate combustor. Compared to the single-channel combustor, the blowout limit of propane/air in the cross-plate combustor can be raised by 0.4â¯m/s at equivalence ratio 0.7. It is also found that the cross-plate length can significantly affect the flame shape in the micro-channel and temperature distribution of the external wall. In contrast, the dimensionless plate length of 5/9 is suggested as the optimal structure parameter for the micro-combustor, which is due to the highest radiation efficiency.
