This paper proposes a microfluidic system for particle manipulation, which is comprised of chip, driving device, manipulation dish, and associated accessories. The chip integrates swirl structure with three microchannels, allowing trapping, rotating, transporting, pairing, enriching particles different parameters by controlling the jet velocity each microchannel. device mainly constructed push–pull syringe pumps to ensure stability flow field during manipulation. Experimental results demonstrate that developed can achieve multifunctional long-term (hours)

Abstract Particle suspension is considered powerful and perspective in enhancing heat transfer, but the unclear nature of particle‐loaded flow limits further understanding particle suspension. Therefore, this paper, orthogonal experiments arbitrary Lagrangian‐Eulerian method were used to investigate transfer characteristics flow. Results indicate that when at inlet microchannel, factors arranged important order are Reynolds number, blockage ratio, initial position, specific capacity, thermal conductivity. When far from microchannel inlet, conductivity, capacity.

The influence of the sharp corner structure advanced flow reactor (AFR) heart-shaped unit developed by Corning Inc. on bubble breakup dynamics was visually investigated. It found that height and angle in AFR could significantly affect behavior change regime range. Three patterns were observed: non-breakup, with partial obstruction, permanent among which obstruction is primary pattern. Under experimental conditions, when are 0.4 mm 90°, range pattern widest. process be divided into squeezing stage, transition rapid pinch-off stage. Furthermore, a correlation for predicting period proposed.

Dean flow existing in sinusoidal channels could enhance the throughput and efficiency for elasto-inertial particle focusing. However, fundamental mechanisms of focusing are still unclear. This work employs four microfluidic devices with symmetric asymmetric to explore over a wide range rates. The effects rheological property, rate, channel curvature, size, geometry on performance investigated. It is intriguing find that makes substantial contribution results illustrate better faster process obtained small curvature radius due stronger flow. In addition, also related diameter properties, larger particles show than smaller particles, rate required achieve stable at outlet higher concentration polyvinylpyrrolidone solutions. Our offers an increased knowledge channels. Ultimately, these provide supportive guidelines into design development high-performance

Microalgae have been remarkably taken into account due to their wide applications in the biopharmaceutical, nutraceutical and bio-energy fields. However, contamination of microalgae with bacteria still appears be a concern, adversely impacting products' quality process efficiency. decontamination conventional techniques is usually expensive time-consuming. Moreover, damage cells highly possible. Asymmetric contraction-expansion microchannels (Asym-CEMCs) are promising passive microfluidic devices that can overcome techniques' drawbacks standing-out features. flexibility Asym-CEMCs performance arising from various tunable geometrical parameters results fact for separating target particle cannot predicted without an investigation. In this work, first time, were numerically studied removal very bacteria, B. subtilis (1 μm), one most popular microalgae, C. vulgaris (5.7 μm). The influences microchannel aspect ratio, length width ratios expansion-to-contraction zones, total flow rate on separation resolution focusing particles investigated by 3D numerical model. ratio had strongest influence Asym-CEMC performance, however, no considerable effect results. A decrease augmented shear-induced lift force Dean drag force, leading significant improvement. was also enhanced increase ratio. Finally, locally optimized 4.7 2.07, respectively, proposed, complete high normalized 0.6. word, tailored dimensions successfully decontaminating bacteria.

Particles focusing in suddenly expanded microfluidic channels with viscoelastic biofluids have attracted increased interests due to the potential biomedical applications. In this work, three types of were designed and employed for experiments. These contained a certain number triangular expansion structures on sides straight channel investigate effect secondary flow particle we investigated behavior those 0.1% hyaluronic acid (HA) solution. The effects various discussed. results indicated that was enhanced by using sudden structures. Consequently, particles multi-peak distributions successfully focused into stream induced structure. Finally, leukocytes explored channels. This work offers deep understanding fundamentals will enable design devices critical applications biomedicine.
