标量混合和湍流剪切层和射流中的化学反应进行了研究，重点是高空间和时间分辨率的实验结果。这样的测量表明，区分分子混合的流体和简单搅拌的流体的概念是有效和有用的。两个模型，似乎特别适合从这个角度来实施混合分析的描述和猜测可能的连接与混沌平流的想法提供。
Scalar mixing and chemical reactions in turbulent shear layers and jets are examined with emphasis on experimental results of high spatial and temporal resolution. Such measurements show that the notion of distinguishing fluids that are molecularly mixed from those that are simply stirred is valid and useful. Two models that seem especially suitable for implementing mixing analyses from this viewpoint are described and speculations on possible connections with the idea of chaotic advection offered.
