Experimental research on cylindrical combustor of micro thermophotovoltaic system

Abstract

Micro combustor is one of the most important components of micro thermophotovoltaic (MTPV) system. The effect of the hydrogen/oxygen mixture ratio e and the diameter of nozzle Φ on the temperature distribution both along the wall and on the exit plane of micro combustor was obtained through the experiment of a thin cylindrical micro combustor. The average temperature along the wall of micro combustor was the highest when e was 1.8. When Φ was 0.7 mm, ε was 1.8, a high and uniform temperature distribution was achieved along the wall of micro combustor, which was suitable for application to MTPV system.
