Semi-Empirical Estimation of Dean Flow Velocity in Curved Microchannels. [PDF]
Sci Rep, 2017 AbstractCurved and spiral microfluidic channels are widely used in particle and cell sorting applications. However, the average Dean velocity of secondary vortices which is an important design parameter in these devices cannot be estimated precisely with the current knowledge in the field.

Dean-flow-coupled elasto-inertial three-dimensional particle focusing under viscoelastic flow in a straight channel with asymmetrical expansion-contraction cavity arrays. [PDF]
Biomicrofluidics, 2015 In this paper, 3D particle focusing in a straight channel with asymmetrical expansion-contraction cavity arrays (ECCA channel) is achieved by exploiting the dean-flow-coupled elasto-inertial effects.

The Asymptotics of Neutral Curve Crossing in Taylor–Dean Flow
Zeitschrift für angewandte Mathematik und Physik, 2006 The fluid flow between a pair of coaxial circular cylinders generated by the uniform rotation of the inner cylinder and an azimuthal pressure gradient is susceptible to both Taylor and Dean type instabilities.

Skewedness as a Signature of Dean Flow Measured by Echo-PIV [PDF]
2022 IEEE International Ultrasonics Symposium (IUS), 2022 Studying secondary flow in the vascular system is of importance, as it is related to hemodynamic parameters such as wall shear stress. Moreover, newly designed helical stents for the superficial femoral artery could induce secondary or swirling flow ...
