Wind Turbine Gust Load Alleviation with Active Flow Control
Energies, 2022 Large wind turbine rotors are becoming more common in utility-scale wind power, especially for offshore wind plants. However, the trend toward large rotors can be limited by their ability to manage dynamic and extreme loads.

Active Control of an Axisymmetric Turbulent Jet Using Moving Delta Tabs
Journal of Fluid Science and Technology, 2008 For the development of an active control of a turbulent jet, measurements of an axisymmetric turbulent jet were performed with multiple “moving delta tabs.” Five computercontrolled delta tabs, which can be driven independently, were installed

INFLUENCE OF MEMBRANE AMPLITUDE AND FORCING FREQUENCY ON SYNTHETIC JET VELOCITY
TASK Quarterly, 2015 This paper presents the results of numerical investigations of a synthetic jet actuator for an active flow control system. The Moving Deforming-Mesh method as a boundary condition is used to capture the real physical phenomenon.

Active Flow Control of a Supercritical Airfoil and Flap with Sweeping Jets
Applied Sciences, 2023 To provide sufficient lift during takeoff and landing, large aircraft are equipped with complicated high-lift devices. The use of simple flaps coupled with active flow control (AFC) can achieve lift improvement while reducing mechanical structure and ...

Plasma Synthetic Jet Actuators for Active Flow Control
Actuators, 2018 The plasma synthetic jet actuator (PSJA), also named as sparkjet actuator, is a special type of zero-net mass flux actuator, driven thermodynamically by pulsed arc/spark discharge. Compared to widely investigated mechanical synthetic jet actuators driven

Active flow control in supersonic nozzles [PDF]
AIP Conference Proceedings, 2018 Active flow control in supersonic nozzle mainly concerns Fluidic Thrust Vectoring (FTV) strategies. Thrust Vectoring in fixed symmetric nozzles can be obtained by generating a local perturbation at wall causing flow separations, asymmetric pressure distributions and therefore, the vectoring of the primary jet thrust. The control action can be steady, e.

Boundaries control active channel flows
Frontiers in Physics, 2022 Boundary conditions dictate how fluids, including liquid crystals, flow when pumped through a channel. Can boundary conditions also be used to control internally driven active fluids that generate flows spontaneously? By using numerical simulations and stability analysis we explore how parallel surface anchoring of active agents at the boundaries and ...
