Paper Abstract

A new passive micromixer has been developed with a low dependence on Reynolds number. The mixer design contains obstructions inside the mixing microchannels to breakup the flow resulting in chaotic mixing. Using CFDRC ACE+ software the mixer was modeled and was shown to completely mix water and glycerin in less than 1 cm. The micromixer was fabricated in cyclic olefin copolymer (COC) using hot embossing with polydimethylsiloxane (PDMS) tools and evaluated using epifluorescence microcopy.
