Abstract

In order to establish a novel technique that estimates the temperature of the near-extinction flamelet of turbulent premixed flames by measuring the emission of the C2 Swan bands, the relation between the temperature and the emission intensity-ratio of the 515.5 nm/470.5 nm bands of C2 of strained premixed flames has been examined by using a counter-flow burner. A unique relation has been found to exist between the flame temperature and the emission intensity-ratio of the 515.5 nm/470.5 nm bands of C2 for the Propane-air strained flame. Therefore, it can be concluded that the temperature of the near-extinction flamelets of Propane-air turbulent premixed flames can be estimated by measuring the emission intensity-ratio of the 515.5 nm/470.5 nm bands of C2.
