... micromixer mixing index micro-PIV Passive mixers do not require external energy; mixing relies on molecular diffusion aided by geometrical manipulations such as generation of chaotic advection [ 10–12 ]. T- and Y-shaped passive micromixers are used to study the fundamentals of mixing processes [ 13...

... at higher Reynolds numbers, owing to the difference in fluid momentum within the channel. The magnitude of a Dean vortex is quantified by the Dean number, K , Fig. 1 Test section depicting locations of measurement A novel, passive, scaled-up micromixer based on fluid rotation is proposed...

...Kristina J. Cook; Ibrahim Hassan 1 Corresponding author. 01 02 2012 02 08 2012 A novel passive enlarged micromixer has been proposed and experimentally and numerically investigated in this study over 0.5 ≤ Re ≤ 100. Flow visualization was applied to qualitatively assess...

... formation can be initiated within a nanochannel even at Reynolds number of the order of 0.02. The formation of vortical flow is an important aspect in developing electrokinetically driven micromixers. The configuration considered here may also provide a simple model of some type of fabrication flaw...
