Micromixing performance of a miniaturized annular rotating flow mixer (MARFM)

Micromixing Performance and Residence Time Distribution in a Miniaturized Magnetic Reactor: Experimental Investigation and Machine Learning Modeling

“…Moreover, a large R extends diffusion distance for mixing, which is especially true for many nanoparticle synthesis and polyvinyl butyral synthesis . It should be noted that the rotating flow field as an effective way for intensifying mixing at operational conditions with relatively large viscosity and large flow rate ratio has been reported in our previous work on the study of MARFM . Second, the energy utilization rate is quite low in many micromixers due to much energy exerted on fluids without direct contacting, and less effective energy contributed to mixing .…”

“…The relationship between t m and X S is shown in Figure S3, where t m and X S follows a log–linear relationship (eq ) whose parameters are shown in Table S2 when t m ranges from 0.01 to 5 ms. Details of the Villermaux/Dushman reaction and the incorporation model are shown in the Supporting Information as well as our previous work t m = true( X S a true) 1 / b …”

“…17 Passive micromixers realize chaotic advection and mixing intensifica-tion by skillfully designing channel structure without utilizing external energy. 18−20 In contrast, active micromixers utilize external force fields such as ultrasound field, 5 high gravity field, 21 electrical field, 22 rotating flow field, 23 or magnetic field 24 to strengthen chaotic advection.…”

“…34 It should be noted that the rotating flow field as an effective way for intensifying mixing at operational conditions with relatively large viscosity and large flow rate ratio has been reported in our previous work on the study of MARFM. 23 Second, the energy utilization rate is quite low in many micromixers due to much energy exerted on fluids without direct contacting, and less effective energy contributed to mixing. 35 Third, many active micromixers are highly integrated and unable to disassemble, resulting in difficult handling at clogging and poor flexibility for catering to applications with different mixing quality demands.…”

“…Micromixers have been widely used in many areas such as polymerization, chemical synthesis, and extraction. , Micromixers can be classified into passive and active micromixers based on whether external energy is utilized . Passive micromixers realize chaotic advection and mixing intensification by skillfully designing channel structure without utilizing external energy. − In contrast, active micromixers utilize external force fields such as ultrasound field, high gravity field, electrical field, rotating flow field, or magnetic field to strengthen chaotic advection.…”
