Characterization of premixed swirling methane/air diffusion flame through filtered Rayleigh scattering
文献摘要：
Characteristics of a premixed,swirl methane/air diffusion flame at atmospheric pressure are measured by filtered Rayleigh scattering(FRS).Three operating conditions are investigated with the equivalence ratios of the methane/air flame covering a range of 0.67-0.83.Under each condition,single-shot and averaged FRS images over a region mea-sured 39.3×65.6 mm2 at seven cross sections of the flame are collected to demonstrate the flame behavior.A gradient calculation algorithm is applied to identify reaction zone locations and structures in the instantaneous FRS measurements.Statistical analysis for the mean FRS measurements is performed by means of joint probability density functions.The experimental results indicate that thermochemical state of the swirl flame is strongly influenced by equivalence ratio,lead-ing to varieties of flame structures and temperature distributions.The gradient of the instantaneous FRS images clearly illustrates the characteristics of the reaction zone.The results also demonstrate that FRS can provide detailed insights into the behavior of turbulent flames.
