Abstract

For detecting the combustion processes more accuracy, ITO thin film thermocouples are designed and fabricated to measure transient wall temperature and heat-flux in combustor. Effects of fuel type and injection pressure on the dynamic characteristics of combustion were quantitative analyzed. The maximum measured wall temperature and heat flux were 550 ℃ and 9.3 MW/m 2 . Additionally, the fluctuations of combustion were analyzed by the frequency spectrum of heat flux, where the combustion of Kerosene has similar frequency but higher amplitude than Hydrogen.
