Soot generation in a turbulent flame is a simultaneous process of formation and surface oxidation. It is difficult to understand this process unless these two phenomena are studied separately. This study considers the behavior of a known soot sample in a non-reacting turbulent medium. LDV, absorption and Schlieren measurements will monitor the history of the soot in a typical propane combustion experiment. The project should illuminate the soot generation process in a variety of generating conditions such as different fuels, mixing ratios and turbulence levels. This new understanding would facilitate fire detection and control, as well as a combustor design.

湍流火焰中的碳烟生成是一个同时发生的过程， 形成和表面氧化。 很难理解 除非这两种现象分开研究。 这项研究考虑了一个已知的烟尘样品在一个 非反应性湍流介质。 LDV、吸收和纹影 测量将在典型的情况下监测烟尘的历史。 丙烷燃烧实验 该项目应阐明烟尘产生过程中， 各种发电条件，如不同的燃料，混合 比率和湍流水平。 这种新的理解将 便于火灾探测和控制，以及燃烧器 设计
