| Research Abstract |
In this study, we present an instantaneous and simultaneous measurement of 2-D mixing behavior and temperature distributions by combining acetone LIF and Rayleigh scattering. We examined air-fuel mixing characteristics in an unburned region where is adjacent to a reaction zone by laser induced fluorescence. Acetone vapor, which fluoresces by UV laser light, was used as a tracer. The CH_4 concentration was estimated from the acetone concentration, which was obtained by acetone LIF intensity. The mixing behavior has been evaluated by measuring CH_4 concentration distributions. It was clarified the suitability of the measurement technique based on the simultaneous measurement and simulation results in a laminar premixed flame. Relationship between inhomogeneous fuel distributions and flame base stability was clarified by simultaneous measurement results in lean premixed flame.
