Description
Summary:The utilization of a Rayleigh scattering photon-correlation technique for flame-temperature measurements is presented. Such measurements are reported for the first time to our knowledge and make use of a digital correlator that permits the determination of temporally varying temperature structures (e.g., coherence structures) for extremely low scattering intensities. The application of low-power cw lasers (e.g., He-Ne lasers) seems also to be possible for the investigation of fast processes in the kilohertz domain. In particle-laden flames the influences of Mie scatterers (e.g., soot particles) can be separated by the different time behavior, which, for those scatterers, is governed by the flow velocity.
