项目摘要

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.
在这项研究中,我们通过将丙酮LIF和瑞利散射结合使用瞬时和同时测量2-D混合行为和温度分布。我们检查了在未燃烧区域中通过激光诱导的荧光与反应区相邻的空气燃料混合特性。丙酮蒸气通过紫外线光荧光荧光,用作示踪剂。从丙酮浓度估算CH_4浓度,该浓度是通过丙酮LIF强度获得的。通过测量CH_4浓度分布来评估混合行为。根据同时测量和仿真结果,阐明了测量技术的适用性。通过同时测量结果阐明了无均匀的燃料分布与火焰基础稳定性之间的关系。
