Efficient electrokinetic non-Newtonian flow mixing in a patterned micro-tube

Physics of Fluids, Journal Year: 2025, Volume and Issue: 37(3)

Published: March 1, 2025

This paper presents a numerical investigation of the micro-mixing behavior non-Newtonian fluid passing through micro-tube with periodic zeta potential and sinusoidal wall roughness. A finite volume approach is utilized to numerically predict flow field two miscible aqueous electrolytes, which are described by power-law model. To explore pressure drop mixing efficiency for wide range wave amplitude (δ), Debye-H ü ckel parameter (κa), index (n), simulations based on Poisson-Nernst-Planck model conducted. The presence charged surface expected increase interfacial contact area between streams. With an in corrugation, Debye length (λ), index, significant improvement expected. Simulation results that value rises up 95% δ=0.5, κa=10, n=1.6. Moreover, thinner EDL, predicted reduce 31% change κa from 10 40 n=1.5 δ=0.5. It also stated increasing n, κa, δ can result larger addition forecasting higher mixing. In order create effective efficient micro-mixer forecast highest possible moderate drop, parametric study conducted analyze performance factor, ratio efficiency, average drop. findings current could be useful thorough design analysis passive micro-mixer, would enable transport polymeric bio-fluids inside micro-devices.

A novel Cantor micromixer with bending mouth structure

Research Square (Research Square), Journal Year: 2025, Volume and Issue: unknown

Published: April 25, 2025

In order to improve the mixing efficiency of passive mixer, we designed a bent Cantor fractal micro-mixer based on principle chaotic convection and folding wave. The influence obstacles height, inlet velocity distance from bending mouth were explore using COMSOL5.3 finite element analysis software. results show that when obstacle height is 0.24mm, at 2mm can reach 92%. However, outlet, lower than 0.21 mm. study found although convective diffusion increases with increase velocity, residence time mixed liquor in mixer also reduced, which disadvantageous for improvement outlet. Through simulation comparison, it 0.675mm, 0.21mm 0.6m/s, outlet 99.8%.
