Investigation of efficient mixing enhancement in planar micromixers with short mixing length

Shuai Yuan et al.

Summary: Achieving rapid mixing of different liquids in a short distance is crucial for biochemical applications. A new type of micromixers consisting of double symmetrical V-shaped baffles and double asymmetrical V-shaped baffles is proposed, which can achieve high mixing efficiency. The performance of the micromixers varies at different Reynolds numbers, with better performance of the symmetrical baffles at low Reynolds numbers and better performance of the asymmetrical baffles at high Reynolds numbers.

Stackable micromixer with modular design for efficient mixing over wide Reynold numbers

Shu Zhu et al.

Summary: Fast and efficient micromixing of different species is crucial in many fields. However, most previous micromixers can only achieve well mixing effects in a narrow Reynold number (Re) range, and the 3D micromixers for improved mixing efficiency are difficult to fabricate. To overcome these limitations, a modular designed micromixer is proposed, which can achieve efficient mixing over a wide Re range.

Shuai Yuan et al.

Summary: This study proposes a passive planar micromixer with narrow gaps and obstacles arranged in mixing units, which utilizes micro-jets and bent baffles to split and recombine streams and promote vortex formation for improving mixing efficiency.
