Passive laminar flow control of crossflow vorticity [PDF]
, 1990 A passive laminar flow crossflow vorticity control system includes an aerodynamic or hydrodynamic surface having geometric perturbations. The perturbations include peaks and valleys having a predetermined spacing and aligned approximately in a streamline

Volumetric velocimetry study in a transitional wall jet flow with passive flow control via flaps [PDF]
, 2014 Birds are remarkably good flyers and show very special adaptations in their wings for stall delay. The pop-up of some cover feathers during starting and landing gave the idea for the present study to investigate the influence on a wall jet when inserting

Passive flow control of Mach 4 mixed-compression intake using chevron grooves [PDF]
FME TransactionsEfficient operation of supersonic intakes is frequently hindered by shock-boundary layer interaction (SBLI), which induces large separation bubbles, pressure losses, and non-uniform flow at the engine face.

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.

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.

Contribution to active and passive Control of Flow around a Cylinder
, 2013 This numerical study aims to develop a coupled, passive and active control strategy of the flow around a cylinder of diameter D, and Re=4000. The strategy consists to put a cylindrical rod in front of a deforming cylinder. The quasi- elliptical deformation of cylinder follow a sinusoidal law in order to reduce the drag force.

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 ...
