A novel tubular microreactor to intensify mixing, namely arc flow inverter (AFI) was proposed and the mixing behavior was investigated. The design concept of AFI expanded a design space of mixing/reactor devices consisting of curved tubes and 90 degrees bends compared with conventional coiled flow inverter (CFI). The fabrication difficulties were overcome by using 3D printing technology. Numerical study on hydrodynamics N_Re ≤ 400 revealed that the profile of Dean vortices was spatially periodic along the axis of AFI. The narrower residence time distribution in AFI compared to CFI implied an enhanced lateral mixing due to the Dean vortices. Micro-mixing time in AFI was experimentally accessed via Dushman-Villermaux reaction. The AFI outperformed other fluidic devices in the literature in terms of the coefficient of mixedness.

提出了一种增强混合的新型管式微反应器，即弧流逆变器（AFI），并研究了混合行为。与传统的盘管流逆变器 (CFI) 相比，AFI 的设计理念扩展了由弯管和 90 度弯管组成的混合/反应器装置的设计空间。使用3D打印技术克服了制造困难。流体力学N _{Re 的}数值研究≤ 400 表明迪恩涡旋的剖面沿 AFI 轴呈空间周期性。与 CFI 相比，AFI 中更窄的停留时间分布意味着由于 Dean 涡流而增强了横向混合。AFI 中的微混合时间通过 Dushman-Villermaux 反应进行实验。AFI 在混合系数方面优于文献中的其他流体装置。
