Abstract Lyons 9612740 The PI proposes to carry out an experimental investigation aimed at making velocity field and scalar field measurements in turbulent diffusion flames (nonlifted, lifted, and acoustically forced). Particle image velocimetry (PIV) will be used to obtain velocity data while planar laser-induced fluorescence (PLIF) will be used to image scalar fields such as those of CH and OH. The goals of the research are: (1) to measure velocity fields in turbulent methane jet flames, (2) to measure the velocity field near the point of stabilization in lifted diffusion flames, (3) to couple these velocity field measurements with the scalar field measurements to better understand how the fllowfield interacts with the combustion front, and (4) to assess the effects of acoustic forcing on the behavior of lifted flames.

摘要里昂9612740 PI建议进行一项实验研究，目的是在湍流扩散火焰（无升力、升力和声学强迫）中进行速度场和标量场测量。 粒子图像测速仪（PIV）将用于获得速度数据，而平面激光诱导荧光（PLIF）将用于图像标量场，如CH和OH。 研究的目标是：（1）测量湍流甲烷射流火焰中的速度场，（2）测量提升扩散火焰中稳定点附近的速度场，（3）将这些速度场测量与标量场测量相结合，以更好地理解流场如何与燃烧前沿相互作用，以及（4）评估声学强迫对升力火焰行为的影响。
