Abstract Accurate control of mixing between two fluids is a fundamental aspect in many applications and generally implies the use small devices operating at low velocities. This often achieved using micromixers which, due to combination dimensions velocities, work laminar regime process very limited flow rates. The rates can be increased more mixers same time. In this respect it appealing sever...

In this paper, a sequence of passive micromixers with spiral patterns on the side wall cylindrical chambers are designed, optimized, prepared and tested. The simulation studies show that vortex magnitude continuity in mixing chamber most important factors to determine performance, while inlet position structural parameters secondary influences their performance. According above principles, perf...

Microfluidic devices have become a new trend in different fields and attracted attention due to their compact size capability deal with small amount of fluid. Micromixing is an efficient way mix miscible fluids at this microfluidic level. This work explores approach for optimization microfluidics, using CFD (Computational Fluid Dynamics) ML (Machine Learning) techniques. The objective combinati...

In the recent years microfluidic technology has affirmed itself as a powerful tool in medical and biological research. Among the different applications, cell manipulation has been widely investigated. Micro-flowcytometers, micromixers, cell sorters and analyzers are only few examples of the developed devices. Various methods for cell manipulation have been proposed, such as hydrodynamic, magnet...

This study presents an integrated microfluidic chip for non-immunologically determining the concentrations of albumin in clinical urine samples. This microchip integrates membrane-type micromixers and a fan-shaped micropump capable of simultaneously and precisely delivering assay reagents to react with 6 urine samples in one single operation. The experimental results show that the coefficient o...

We present a new approach to enhance mixing in T-type micromixers by introducing a constriction in the microchannel under periodic electro-osmotic flow. Two sinusoidal ac electric fields with 180 degrees phase difference and similar dc bias are applied at the two inlets. The out of phase ac electric field induces oscillation of fluid interface at the junction of the two inlet channels and the c...
