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 ...

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.

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. The engineered bio-inspired coating presented here aims

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 ...

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.

A unifying passivity framework for network flow control [PDF]
IEEE INFOCOM 2003. Twenty-second Annual Joint Conference of the IEEE Computer and Communications Societies (IEEE Cat. No.03CH37428), 2003 Network flow control regulates the traffic between sources and links based on congestion, and plays a critical role in ensuring satisfactory performance. In recent studies, global stability has been shown for several flow control schemes. By using a passivity approach, this paper presents a unifying framework which encompasses these stability results ...

Numerical Study of Cylinder Drag Coefficient Reduction Using Passive Flow Control [PDF]
مهندسی مکانیک شریف, 2022 In this study, the cylinder drag coefficient is reduced by using passive flow control. Installing a flat plate in two heights and different longitudinal distances in upstream flow increases the upstream flow momentum of the cylinder, leading to the ...

Comparison of Passive Flow Control Methods for a Cavity in Transonic Flow [PDF]
Journal of Aircraft, 2016 A comparative study of different passive control techniques was conducted on a cavity with a length of 320 mm with length-to-depth and length-to-width ratios of five and two, respectively. The tests were conducted at a freestream Mach number of 0.71. Both leading-edge and trailing-edge modifications were included in the studies.
