Abstract
A technique has been developed for obtaining spatially resolved measurements of temperature and density under combustion conditions. The spectral structure of Rayleigh scattered laser light is determined using a Fabry-Perot interferometer. Spectra in the post-combustion zone exhibit simple Doppler broadening with a Gaussian line profile; however, spectra in the higher density, precombustion zone have appreciable Brillouin components. Radial and axial surveys of temperature and intensity in the premixed hydrogenair flame issuing from a 3.2 mm diameter welding torch tip are obtained. Measured temperatures in the post-combustion zone are in agreement with the adiabatic flame temperature.
