摘要：

This paper presents a hydrogen-fueled micro-combustion system for thermophotovoltaic application. The thermal performances of the micro-combustor with and without baffles have been investigated numerically and experimentally. Dimensionless height lambda and distance delta are defined to determine the optimal height and location of the baffles. The highest combustion efficiency is achieved when delta and lambda are 0.3 and 0.9, respectively. The blowout limit is extended for the combustors with baffles. Besides, the heat from exhaust gas is recycled to preheat the fresh H-2-air mixture, thereby increasing the mean wall temperature. A high H-2-air mass flow rate will increase the fresh gas temperature but lead to low heat recovery rate. (C) 2013 Elsevier Ltd. All rights reserved.
