Research on 2D Temperature Field Measurement Method of Mg/CO2 Combustion Flame Based on Color CCD
IOP conference series(2020)
Abstract
A new Mg/CO2 powder rocket propulsion system is proposed for Mars exploration. Accurate measurement of Mg/CO2 combustion flame temperature field has important reference value for understanding the combustion characteristics and operating conditions. In this paper, the two dimensional temperature field of the Mg/CO2 combustion flame is obtained by building a Mg/CO2 combustion device and colorimetric temperature measurement system based on the color charge coupled device (CCD). The influence of magnesium powder particle size, premixed Reynolds number, and CO2/Mg oxygen fuel ratio on the flame temperature of Mg/CO2 combustion are discussed. The results show that the maximum temperature of Mg/CO2 combustion flame under different working conditions is between 2500K and 2900K, and it increases with the increase of magnesium powder particle size, premixed Reynolds number, and oxygen-fuel ratio.
