A serpentine laminating micromixer combining splitting/recombination and advection [PDF]
Mixing enhancement has drawn great attention from designers of micromixers, since the flow in a microchannel is usually characterized by a low Reynolds number ( Re) which makes the mixing quite a difficult task to accomplish.

Geometric effects on mixing performance in a novel passive micromixer with trapezoidal-zigzag channels [PDF]
A novel passive micromixer, called a trapezoidal-zigzag micromixer (TZM), is reported. A TZM is composed of trapezoidal channels in a zigzag and split–recombine arrangement that enables multiple mixing mechanisms, including splitting–recombining ...
