Abstract: A modular micro-TPV system was introduced in this work. Compared to the cylindrical structure, the modular TPV system has the advantages of easier fabrication and assembly. A micro combustor is a key component of the micro-TPV system. In order to maximize the power output, higher wall temperature and uniform distribution along the combustor wall is desirable. A micro cylindrical combustor (inner diameter d = 3.56 mm) and three kinds of micro modular combustors with the widths of 1.0 mm, 1.5 mm and 2.0 mm are experimented with. The results indicate that the micro modular combustor with a width of 1 mm has a much higher radiation efficiency than the micro cylindrical combustor. The wall temperature decreases with the increase of width due to the reduced heat transfer between the wall and hot gases. The performance of the micro modular TPV system is also predicted. © 2010 IOP Publishing Ltd.
