The book is dedicated to analysis and design optimization of micromixers. The
contents of the book were presented in a sequence starting from applications
(Chap. 1), mixing concepts (Chaps. 1 and 2), flow and mixing analyses (Chap. 3)
and design optimization (Chap. 4) of micromixers. Major emphases was laid on
numerical analyses of flow and mixing in micromixers, and design optimization
techniques.
Chapter 1 provides introduction to micromixers in light of wide variety of chemical and biological applications, types of micromixers, and characterization of flow
and mixing regimes based on dimensionless numbers. A few selected applications of
micromixing technology were presented, but the readers can refer to the cited references for more detailed and involved applications to develop a broad background
on the researches. The dimensionless numbers were introduced to provide measures
of relative effects which play important role in determining how mixing occurs in
various micromixers. The analysis based on the dimensionless numbers can be of
great help to practitioners and designers in classifying different micromixers, and
determining suitability of a micromixer to a particular application.
Chapter 2 gives overview of different types of active and passive micromixers.
Active micromixers uses external energy to perturb the flow field for efficient mixing.
Some basic types of active micromixers were covered based on pressure field, pulsation, electrokinetics, magnetohydrodynamics, acoustics, and Coriolis induced flows.
On the other hand, passive micromixers rely on the geometry of the devices to produce
complex flow fields for mixing. Due to certain advantages of passive micromixing
concept over the active type, different concepts and designs of passive micromixers
were the focus of this chapter.
Two basic concepts were presented: multi-lamination and focusing which rely
solely on molecular diffusion for mixing enhancement, and chaotic advection which
