Flow study of Dean’s instability in high aspect ratio microchannels

open access: yesScientific 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 $$De>162$$

Order breaking in Dean flow

open access: yesPhysics of Fluids A: Fluid Dynamics, 1991
The idea of combining large vortical structures in the flow with the dynamical behavior of open systems to enhance heat transfer and mixing has led to the design and construction of an experimental apparatus to study order breaking in such systems.

Conception of a compact flow boiling loop for the International Space Station- First results in parabolic flights

open access: yesComptes Rendus. Mécanique, 2023
The design of a pipe flow boiling experiment for the International Space Station is proposed, taking into account typical weight, power consumption and size constraints. The effect of singularities such as elbows upstream the test section is investigated.

Switchable 3D optofluidic Y-branch waveguides tuned by Dean flows [PDF]

open access: yesScientific Reports, 2016
AbstractOptical branch waveguides are one of the most important optical elements and have been widely exploited for optical communication systems. However, prevailing devices are typically solid and have limit in tunability. Liquid optical devices have attracted more interest for the advantage of tunability of liquid media, but their signals suffer ...
