Raman-scattering measurements have been performed to investigate the effect of flame/wall interactions on unburned hydrocarbon emissions. An impervious cold (isothermal) flat wall was placed perpendicular to a laminar premixed propane/air flame, stabilized on a heat-sink-type one-dimensional-flame burner. A conventional spontaneous-Raman-scattering apparatus was utilized to obtain high-spatial-resolution data in the vicinity of the wall-burner interface. Spatial scans were obtained by translating the burner assembly with micrometer screws. Nitrogen number densities were determined by measuring Q-branch Raman spectra and by applying computer-generated corrections. The resultant densities were converted to temperatures by utilizing the isobaric nature of the flame. 4 refs.
