Downstream decay of fully developed Dean flow
Journal of Fluid Mechanics, 2015Direct numerical simulations were used to investigate the downstream decay of fully developed flow in a $180^{\circ }$ curved pipe that exits into a straight outlet. The flow is studied for a range of Reynolds numbers and pipe-to-curvature radius ratios.

Dean flow of a Bingham fluid in a curved rectangular duct
Journal of Non-Newtonian Fluid Mechanics, 2020Abstract In this paper we study the flow of a Bingham fluid on a curved (rectangular) pipe. Flows in this kind of geometries present secondary flows due to presence of centripetal forces in the radial direction. This so called Dean Flow has been extensively studied for Newtonian fluids.

Study of flow and mixing of dean flow and dean instability in inertial microfluidics
Inertial microfluidics is an emerging field deviates from the conventional microfluidics due to its unqiueness in consideration of inertia. Dean flow and Dean instability play an important role in inertial microfluidics, with a wide application in mixing and sorting. However, most studies are limited to Dean flow on the microscale.

The Importance of Dean Flow in Microfluidic Nanoparticle Synthesis: A ZIF‐8 Case Study
Small Methods, 2023The Dean Flow, a physics phenomenon that accounts for the impact of channel curvature on fluid dynamics, has great potential to be used in microfluidic synthesis of nanoparticles.

A purely elastic instability in Dean and Taylor–Dean flow
Physics of Fluids A: Fluid Dynamics, 1992The linear stability of the viscoelastic flow of an Oldroyd-B fluid between rotating cylinders with an applied, azimuthal pressure gradient is considered. It is found that this Taylor–Dean flow is unstable in certain flow parameter regimes even in the limit of vanishingly small Reynolds number.
