From: Dean Flow Dynamics in Low-Aspect Ratio Spiral Microchannels
(a) Schematic illustrating two counter rotating vortices in a curved rectangular channel at low De. caused by the effect of centrifugal (FCF) and centripetal (FCP) forces on the parabolic velocity profile. (b) Schematic illustrating flow behavior at high De causing the formation of multiple vortices.
