Abstract:

This report summarizes progress in the study of the ignition mechanism of a liquid fuel by a CW CO2 laser the period covered is from October 1, 1979 to September 30, 1982. It describes 1 new observations of liquid fuel behavior near and at the liquidair interface during the laser irradiation with incident fluxes from 260 to 2500 Wcm2, 2 new time-resolved measurements of temperature and vapor concentration distributions in the gas phase using a newly-developed, high speed, two-wavelength holographic interferometer, and 3 the development of a technique to measure infrared absorption spectra of fuel vapors at elevated temperatures.
