title: Single-pulse, simultaneous multipoint multispecies Raman measurements in turbulent nonpremixed jet flames.
abstract: An imaging technique based on Raman scattering induced by a KrF excimer laser has been developed for quantitative simultaneous multiple-point measurements of absolute multispecies concentrations (O(2), N(2), H(2), and H(2)O) and temperature in turbulent flames. These multiparameter measurements along the laser line have a temporal resolution of 17 ns, a spatial resolution of 0.7 mm for each point, and single-shot standard deviations of ~8%. The UV Raman imaging system has been applied in turbulent nonpremixed hydrogen-air flames, providing what are to our knowledge the first reported single-pulse, simultaneous multiple-point quantitative images of multiple species and temperature.
