A novel width-expanding spiral microchannel for high-throughput continuous separation of bacterial-sized particles [PDF]

Scientific Reports
Separating target particles (e.g., bacteria) from complex media is critical to preventing matrix interference in the detection and analysis of target substances.

Numerical Investigation of Vortex-Induced Enhancement in the Mixing Characteristics of Double-Spiral and Serpentine Microchannels [PDF]

Micromachines
To enhance passive mixing in microchannels, T-shaped double-spiral and serpentine microchannels with identical curvature radii were designed and numerically analyzed across a Reynolds number (Re) range of 1 to 300.

Order breaking in Dean flow

Physics 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

Comptes 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.
