Flow study of Dean’s instability in high aspect ratio microchannels
Scientific Reports, 2023 AbstractDean’s flow and Dean’s instability have always been important concepts in the inertial microfluidics. Curved channels are widely used for applications like mixing and sorting but are limited to Dean’s flow only. This work first reports the Dean’s instability flow in high aspect ratio channels on the deka-microns level for $$De>162$$
