在泰勒-库埃特流中研究了光解作用，并提出了在层流泰勒涡流存在下通过快速光化学反应形成产物的相似定律。形成的产物的浓度取决于光子的剂量和由辐射穿透深度定义的反应层厚度。特别是，对于给定的流速和辐射强度，当辐射穿透深度等于速度边界层厚度时，碘化物的紫外光解产生产物三碘化物的最大浓度。后一个结论提供了最佳操作条件，以最大化泰勒数或旋转频率方面的产量。
Photolysis was studied in Taylor–Couette flow, and a similarity law proposed for the formation of a product from a fast photochemical reaction in the presence of laminar Taylor vortices. The concentration of the product formed depended on both the dosage of photons and a reaction-layer thickness, defined by the radiation penetration depth. In particular, for a given flow rate and radiation intensity, the UV photolysis of iodide produced a maximum concentration of the product triiodide, when the radiation penetration depth was equal to the velocity boundary-layer thickness. The latter conclusion provides optimum operating conditions to maximize yield in terms of the Taylor number or frequency of rotation.
