“…In the case of poor mixing, the acid can react with iodide and iodide surrounding ions to yield iodine I 2 , after complete consumption of borate ions. Therefore, the concentration of the product of reaction (9), I 3 − , can characterize the mixing efficiency, and the segregation index X s is defined as follows 31 :

X_{s} goodbreak= \frac{Y}{Y_{ST}}

where Y denotes the ratio of the number of moles of acid consumed by reaction (8) to the total number of moles of acid:

Y goodbreak= \frac{2 ((), n_{{normalI}_{2}} goodbreak+ n_{{normalI}_{3}^{-}})}{n_{H_{0}^{+}}} goodbreak= \frac{4 ((), C_{{normalI}_{2}} goodbreak+ C_{{normalI}_{3}^{-}})}{C_{H_{0}^{+}}}

Also, Y ST denotes the value of the ratio Y in total segregation when mixing is infinitely slow:

Y_{ST} goodbreak= \frac{6 C_{{IO}_{3}_{0}^{-}}}{6 C_{{IO}_{3}_{0}^{-}} + C_{H_{2} {BO}_{3}_{0}^{-}}}

The unknown values,

C_{{normalI}_{3}^{-}}

and

C_{{normalI}_{2}}

, can be calculated as follows 33 :

C_{{normalI}_{3}^{-}} goodbreak= \frac{A}{K_{normalε}}

\frac{5}{3} C_{{normalI}_{2}}^{2} goodbreak+ ((), \frac{8}{3} C_{{normalI}_{3}^{-}} goodbreak- C_{{normalI}_{0}^{-}}) C_{{normalI}_{2}} goodbreak+ \frac{C_{I_{3}^{-}}}{K_{normalB}} ...

BACKGROUND Throughput, mixing efficiency and pressure drop are three key performance indicators of a mixer or reactor. However, it is difficult to simultaneously achieve high throughput, high mixing efficiency and low pressure drop in a traditional mixer. RESULTS A novel mixer was designed and constructed by adding an ellipsoidal baffle to a large‐scale Y‐shaped mixer (YEBM) through computational fluid dynamics. The effects of ellipsoid period length, short and long axes, rotation direction, rotation angle and entrance angle of the mixer on mixing and flow characteristics were investigated and optimized. Compared with a 1 mm mixer, the throughput of the optimized YEBM is increased 100 times, the mixing efficiency is comparable and the pressure drop is reduced by 7.4%. Additionally, the application range of the YEBM with high mixing efficiency is extended to 499.1 < Re < 999.8. CONCLUSIONS The results showed that the novel ellipsoidal baffle mixer could effectively enhance performance and reduce the pressure drop on the premise of ensuring high throughput. All the findings reported provide useful references for enhancement of mixing efficiency and reduction of pressure drop in a large‐scale mixer. © 2022 Society of Chemical Industry (SCI).

“…A large number of complex structure designs, which are of great signi cance in various elds, eventually come true with the help of AM technology. For example, Wang et al [5] designed a novel micromixer with complex 3D-shape inner units which is of great value in the chemical industry and manufactured it through SLM. The performance and the mechanism of the novel micromixer were investigated by the Villermaux-Dushman reaction system and Compute Fluid Design (CFD) simulation.…”
