“…The impact of the positioning angle on the mixing efficiency diminishes as the increase of the number of folding plates increases. However, the enhancement of axial and radial heat and mass transfer as well as kinetic energy diffusion, with these optimisations is still not promising for highly viscous fluids 16 .…”

Reciprocating mixing is a novel mixing technique designed to enhance mixing efficiency. In this method, the mixing paddle moves back and forth along the axial direction periodically, unlike conventional mixing methods. The mixing efficiency of reciprocating stirring can be significantly enhanced compared to conventional stirring. In this thesis, the flow field characteristics and numerical simulation of the Rushton pulp reciprocating mixing tank are analyzed using the Computational Fluid Dynamics (CFD) method with VOF and UDF function control. It has been found that reciprocating mixing increases the overall speed of the fluid by about 8%, the turbulent kinetic energy by 35%-45%, and the turbulent kinetic energy dissipation rate by 10%-16% compared with conventional mixing. Reciprocating mixing significantly affects the tank basin, enhancing the axial flow of the fluid in the tank, disrupting the circulating structure of conventional agitation, and dynamically integrating the multiple flow regions of conventional agitation to improve mixing homogeneity. Additionally, the evolution process of vortex generation, development, and extinction by reciprocal stirring is quantitatively analyzed to determine the optimal size of paddle discs under different conditions. The maximum values of turbulent kinetic energy in the two stirring modes are FS-4/12D and RS-5/12D, respectively. The reason for the abrupt decrease of turbulent kinetic energy in RS-4/12D is explained as follows: The uncaused quadratic flow variance indicates that the reduction of the tail vortex size can effectively destroy the reflux zone, thus reducing the energy consumption at the tail vortex and allowing more energy to be used for fluid mixing. The results of this paper provide a theoretical basis and reference data for the engineering application of reciprocating mixing.

Droplet-based microreactors often uncover fascinating phenomena and exhibit diverse functionality, which make them applicable in various fields. Liquid marbles (LMs) are non-wetting droplets coated with particles, and these features highlight their potential as microreactors. However, sophisticated experimental designs are typically hindered because it is difficult to obtain sufficient substance mixing in these miniature, damage-prone, selfsupporting liquid containers. Here, we demonstrate that subjecting LMs to vertical oscillations by audio signals represents a controllable approach that allows sufficient mixing with variable dynamic modes. The characteristics and key issues in LM oscillation are systematically explored. The effects of oscillation on application potential are examined. Under oscillation conditions, homogeneous mixing can be achieved within a few seconds in LMs consisting of either water or viscous liquids. Importantly, the structures of materials synthesized in LMs can be regulated by modulating the oscillation modes. The variable modes, flexible adjustability, high efficiency, and wide applicability of this oscillation method make it a verified manipulation strategy for advancing the functionality of LM microreactors.

The use of LMs as a three-dimensional niche environment for cell culture deserves to be emphasized.…”
