Microfluidic flow-cell with passive flow control for microscopy applications. [PDF]
PLoS ONE, 2020 We present a fast, inexpensive and robust technique for constructing thin, optically transparent flow-cells with pump-free flow control. Using layers of glass, patterned adhesive tape and polydimethylsiloxane (PDMS) connections, we demonstrate the ...

Engineered bio-inspired coating for passive flow control. [PDF]
Proc Natl Acad Sci U S A, 2018 Significance Flow separation on moving bodies has a negative effect on energy efficiency. Reducing recirculating regions is key in the design of energy-efficient systems. Efficient design decreases fuel consumption and pollutant emissions, including the systems’ carbon footprint.

Active and Passive Flow Control of Turbomachines [PDF]
International Journal of Rotating Machinery, 2013 Turbomachines are used in a wide range of applications. Increasing the efficiency and operating range of turbomachines reduces fuel consumption of gas turbine power plants and other applications. Over the years, many attempts have been made to achieve these objectives.

Passive flow control valve for protein delivery
Cogent Engineering, 2017 Passive flow control valves are usually intended to deliver or drain a fluid at a constant rate independently of pressure variations. Microfluidic devices made of a stack of two plates are considered here: the first plate comprises a flexible silicon ...

Passivity-Based Output-Feedback Control of Turbulent Channel Flow [PDF]
Automatica, 2016 This paper describes a robust linear time-invariant output-feedback control strategy to reduce turbulent fluctuations, and therefore skin-friction drag, in wall-bounded turbulent fluid flows, that nonetheless gives performance guarantees in the nonlinear

The development of passive flow control vortices [PDF]
, 2004 Surface flow visualisation and Particle Image Velocimetry (PIV) were used to investigate the flow-field of sub-boundary layer vane vortex generators (VVGs) and steady jet vortex generators (SJVGs) in a separated flow at 20m/s.

Active and Passive Flow Control around Simplified Ground Vehicles
Journal of Applied Fluid Mechanics, 2012 The aim of this work is to control the flow around ground vehicles by active or/and passive strategies. The active control is achieved by steady, pulsed or closed-loop jets located at the backof the simplified car model.

Cavitation control using passive flow control techniques [PDF]
Physics of Fluids, 2021 Passive flow control techniques, and particularly vortex generators have been used successfully in a broad range of aero- and hydrodynamics applications to alter the characteristics of boundary layer separation. This study aims to review how such techniques can mitigate the extent and impact of cavitation in incompressible flows.
