Simultaneous Measurements of Local Temperature and Chemiluminescence by Cassegrain Optics

1st Report, Measurement System and Error Estimation

Abstract

Distributions of local flame temperature and chemiluminescence of OH^*, CH^* and C radicals were simultaneously measured in laminar premixed flames. The temperature measurement is based on the Rayliegh scattering method. The Cassegrain optics was used to measure the chemiluminescence and Rayleigh scattering with high spatial resolution. Relationships between the local flame temperature and chemiluminescence intensities were examined. As a result, it became clear that there was a close relation between temperature and the ratio of OH^* and CH^* chemiluminescence intensity.
