Effect of hydrodynamic heterogeneity on micromixing intensification in a Taylor–Couette flow (TC) reactor with variable configurations of inner cylinder has been investigated by adoption of a parallel competing iodide-iodate reaction system. Two types of inner cylinder, circular inner cylinder and lobed inner cylinder (CTC and LTC), were used to generate hydrodynamic heterogeneity, focusing on the effects of the Reynolds number, the acid concentration, and the feeding time on the micromixing performance. Segregation index (Xs) was employed to evaluate the micromixing efficiency. It is revealed that Xs decreases with the increase of Reynolds number and feeding time but increases with the increase of acid concentration for both the CTC and LTC. However, the LTC does present a better micromixing performance at various operating conditions than that of the CTC as affirmed by both the experimental and computational fluid dynamics simulation results.

流体动力非均质性对内筒可变构型 Taylor-Couette 流动反应器中微混合强化的影响

通过采用平行竞争的碘化物 - 碘酸盐反应系统，研究了流体动力学异质性对具有可变内筒配置的 Taylor-Couette 流 (TC) 反应器中微混合强化的影响。两种类型的内筒，圆形内筒和叶形内筒（CTC 和 LTC），用于产生流体动力学非均质性，重点研究雷诺数、酸浓度和进料时间对微混合性能的影响。偏析指数（X s）用于评估微混合效率。据透露，Xs 随着雷诺数和进料时间的增加而降低，但随着 CTC 和 LTC 酸浓度的增加而增加。然而，正如实验和计算流体动力学模拟结果所证实的那样，LTC 在各种操作条件下确实呈现出比 CTC 更好的微混合性能。
