OH 自由基的高速平面激光诱导荧光 (PLIF) 成像在湍流非预混合甲烷-空气火焰中呈现。最多八个连续 PLIF 图像的序列可以以多种 id-It 重复率顺序解析，湍流现象（例如涡流形成和流动中的空气夹带）可以可视化，并可以实时跟踪它们的发展。可以使用所提出的系统来研究湍流/化学相互作用，例如局部消光和重燃及其时间演化。
High speed planar laser induced fluorescence (PLIF) imaging of the OH radical is presented in a turbulent nonpremixed methane-air flame. Sequences of up to eight successive PLIF images could be resolved sequentially at several id-It repetition rates, Turbulent flow phenomena such as vortex formation and air entrainment in the flow could be visualised and their development tracked in real time. Turbulence/chemistry interactions such as local extinction and re-ignition and their temporal evolution can be studied with the presented system.
