- 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 liquid/air interface during the laser irradiation with incident fluxes from 260 to 2500 W/cm(2), (2) new time-resolved measurements of distributions of temperature and vapor conentration 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.
