due to transverse velocity variations in a phenomenon now commonly referred to as Taylor dispersion.
It is well understood that the characteristics of the dispersion are sensitive to the channel’s cross-sectional
geometry. Here we demonstrate a method for manipulation of dispersion in a single microchannel via controlled
deformation of one side of the channel’s walls. Using a rapid-prototyped multi-layer microchip, the
lower channel wall is deformed by an external pressure source allowing us to characterize the dependence
of the dispersion on the deflection of the channel wall and overall channel aspect ratio. Our experimental
measurements are compared directly with theoretical predictions.</mods:abstract><mods:subject><mods:topic>Fluid Dynamics</mods:topic></mods:subject><mods:subject authority="fast" authorityURI="http://id.worldcat.org/fast" valueURI="http://id.worldcat.org/fast/01736696"><mods:topic>Microfluidics</mods:topic></mods:subject><mods:subject><mods:topic>Taylor Dispersion</mods:topic></mods:subject><mods:subject><mods:topic>Rapid-prototyped microchip</mods:topic></mods:subject><mods:language><mods:languageTerm authority="iso639-2b">English</mods:languageTerm></mods:language><mods:recordInfo><mods:recordContentSource authority="marcorg">RPB</mods:recordContentSource><mods:recordCreationDate encoding="iso8601">20200720</mods:recordCreationDate></mods:recordInfo><mods:identifier type="doi">10.26300/anjp-7w21</mods:identifier><mods:accessCondition type="rights statement" xlink:href="http://rightsstatements.org/vocab/InC/1.0/">In Copyright</mods:accessCondition><mods:accessCondition type="restriction on access">All rights reserved.
