“…Their results showed that the rapid change of channel size could lead to the pressure drop of the fluid impacting the wall and the gas phase accelerates in the throat, thus improving the mixing efficiency. Qaderi et al [20] established a two-dimensional microchannel model of triangular obstacles under the condition of heterogeneous zeta-potential. Their results presented that higher hurdles could improve the mixing efficiency and reduce the mass flow rate in microchannels.…”

“…One of the factors, having a great effect on increasing mixing percentage in micromixers, is geometrical changes and the presence of obstacles along the fluid path, which was examined in active micromixers [20]. Compared to T-shaped micromixers, geometrical changes of the mixing chamber and the presence of obstacles with different shapes would yield much better results [21].…”

Micromixers are crucial parts of microfluidic systems when it comes to efficiency and precision, as mixing is the central process in most relevant applications, including medical diagnosis, chemical production, and drug discovery. In view of the importance of improving the mixing quality, for the first time, the present work investigates the simultaneous effects of mixing chamber geometry (circular, hexagonal, and octagonal), electric field frequency (5, 7, 10, and 15 Hz), inlet velocity (0.1-0.2 mm·s−1), and phase difference (0-π) on the flow inside an electroosmotic micromixer using the finite-element tool COMSOL Multiphysics 5.4 to optimize the process and achieve homogeneous mixing. The flow-field, concentration-field, and electric-field equations were coupled and solved simultaneously. The results of this research indicated that at a given inlet velocity and a specific frequency range, as frequency increases, more mixing occurs in a smaller chamber, and as the inlet velocity increases, more mixing occurs in a smaller chamber at a higher frequency. Moreover, the highest mixing level (98.16%) was obtained with a 0.1 mm·s−1 inlet velocity, 10 Hz frequency, and π/2 phase difference in a hexagonal chamber.

This paper explores the electro‐osmotic flow with a uniform magnetic transverse field and thermal radiation. An investigation has been conducted on electromagnetohydrodynamics (EMHD) boundary layer past a moving upright accelerated plate in hybrid nanoliquids. Two specific water‐based hybrid nanoliquids are taken into account, which include copper and aluminum oxide. To define the electrical potential distribution in the fluid medium, the Poisson–Boltzmann distribution is used and linearized by Debye–Huckel. The control equations are solved by the transformation technique of Laplace and results are obtained in a closed shape. The quantitative analysis of the nanoliquid temperature, axial velocity, and Nusselt number on the accelerated plate for several values of the related parameters is shown by a graph. Hybrid nanoliquids are known to create fluid flows significantly larger than nanoliquids, which are very helpful in cleaning the contaminated water in a nuclear plant.
