Abstract This paper presents a new type of three‐dimensional variable‐angle electro‐osmotic micromixer. By introducing the electric field effect into it, voltage, baffle structure, and electrode structure in mixing process are studied. The results show that when voltage value is close to 1 V baffles alternately placed at an angle 30°, micromixer performs best. At low Reynolds numbers (Re), closely related efficiency, which proves alternating placement microelectrodes can effectively improve efficiency. study provides method for improving efficiency micromixers has broad application prospects many fields such as chemical analysis, drug delivery, biological detection.

This work aims to find the optimum value of blade height ratio (R) for improving mixing performance and energy consumption a Triple-Blade Concentric Double-Helix Static Mixer. In this study, two fluids at different concentrations subjected laminar flow conditions is numerically analyzed by using finite element-based Computational Fluid Dynamics simulations. Different values R parameter are considered in wide range Reynolds numbers (Re = 200–1000). analysis then carried out an in-depth study R's effect on performance, strength segregation, index, helicity, velocity profile, pressure drop, pumping power, efficiency. The findings showed that 2/3 gave highest index (MI), with maximum 0.99 Re number 600, which best channel. Helicity visualization also complex helicity patterns increased vortex interactions configuration. geometry improvement MI about 17.85% over Single-Helix Mixer (TB-CSH-SM) 0 600. It important mention increasing leads increase drop and, consequently, consumption. Although gives relatively higher than 0, has lowest power input but lower MI. investigation concludes represents balanced solution since it realizes moderate hence suitable applications requiring efficient compromise between quality
