Publication number: 20210023514Abstract: Disclosed herein are continuous flow systems having bifurcated fluidic flow mixers. The mixers operate, at least partially, by Dean vortexing. Accordingly, the mixers are referred to as Dean Vortex Bifurcating Mixers (“DVBM”). DVBMs utilize Dean vortexing and bifurcation of the fluidic channels that form the mixers to achieve the goal of optimized microfluidic mixing.Type: ApplicationFiled: October 7, 2020Publication date: January 28, 2021Applicant: The University of British ColumbiaInventors: Euan Ramsay, Robert James Taylor, Timothy Leaver, Andre Wild, Kevin Ou, Colin Walsh
