Hydrodynamic Focused Passive Separation Under Continuous Flow in a Microfluidic Chip
<p>A continuous flow, passive separation device was designed using an equivalent circuit to create variable flow rates for hydrodynamic focusing to drain channels and collection outlets. By varying the diameter of the sample inlet connection into the reservoir, the particle position was influenced …

Active and passive separation control for drag reduction of a maneuvering hull form
Boundary layer separation is a source of large fluid dynamic forces on many engineered vehicles and structures, limiting the speed and efficiency at which we transport people and goods. The maneuvering of ocean and air vehicles in particular is limited by resistance due to cross-flow separation. …

Passive Turbulent Boundary Layer Control through 3D-Printed Dolphin Skin
… truncates) skin to mitigate boundary layer separation as a form of passive flow control, energizing the flow near the wall. A water tunnel generates a tripped turbulent boundary layer across a vertical test plate, and a rotating cylinder induces flow separation by creating an adverse …

Portable blood plasma separation for point of care diagnostics
… a loading syringe and collection tubing. The separation results show 10-100 times improvement in plasma purity over the literature values for passive separation designs. This separation system was then combined with a colorimetric malaria sensor that produced a visually detectable colored …

An Investigation of Dolphin-Groove Inspired Surface Patterning on Flow Control
… in many flow applications is boundary layer separation; this study investigates the passive separation control mechanism that could result from the micro-grooves found on dolphin skin (Tursiops truncates). A water tunnel was used to study a turbulent boundary layer over rigid 3D printed …

Passive Flow Control with Shark Skin and the Relevance of Low Speed Streaks to Denticle Actuation
… as scales, which may be crucial to delaying flow separation. The teeth-like denticle morphology and flexibility of the scales measured by bristling angle vary along the shark's streamlined body [1]. Scales with narrow and long crowns have higher bristling angles at strategic locations, such as the …
