Optimization of micromixer with Cantor fractal baffle based on simulated annealing algorithm
Chaos, Solitons & Fractals, 2021To maximize the mixing performance of the micromixer with the Cantor fractal baffle structure, single-objective optimization of the micromixer with different Reynolds (Res) is carried out.

Machine learning-augmented fluid dynamics simulations for micromixer educational module.
Biomicrofluidics, 2023Micromixers play an imperative role in chemical and biomedical systems. Designing compact micromixers for laminar flows owning a low Reynolds number is more challenging than flows with higher turbulence.

Summary: Magnetohydrodynamic mixing of two fluids in an annular microchannel is modelled as a two-dimensional laminar convection-diffusion problem and examined using asymptotic analysis and numerical simulation. The time \(T\) required for mixing of a plug of solute depends on the Péclet number Pe and on the geometry of the annulus.

Electrokinetic Instability Micromixing
Analytical Chemistry, 2001We have developed an electrokinetic process to rapidly stir micro- and nanoliter volume solutions for microfluidic bioanalytical applications. We rapidly stir microflow streams by initiating a flow instability, which we have observed in sinusoidally oscillating, electroosmotic channel flows.
