Title:
TIME-RESOLVED SPECTROSCOPY OF SINGLE BURNING METAL PARTICLES.

Abstract:
A single metal particle burning in a stream of laminarly flowing gases leaves a straight narrow trajectory. An optically fast slitless spectrograph with 80 Amm dispersion has been assembled which focuses on the particle trajectory and thus records time-resolved spectra of such burning particles. So far, the instrument has been applied to a study of burning aluminum and titanium particles, 30 and 50 microns in diameter. In both cases, the spectrograms show metal Al and Ti vapor lines and bands of the respective diatomic oxides. Systematic intensity variations of these features were observed with time-resolution of less than a millisecond. Pertinence of these observations to particle combustion mechanism is briefly discussed. Author
