Influence of different blowing parameters on flow control on an airfoil
A numerical study on flow separation control is conducted for an airfoil with a blowing jet. In this regard, the effect of different parameters of air blowing on stall controlling and flow structure over NACA 0012 is followed.

Nacelle intake flow separation reduction at cruise condition using active flow control
Turbofan engine intakes are designed to provide separation-free flow at the fan face over a wide range of operating conditions. But at some off-design conditions, like at high flight speeds and high angles of attack (AoA), the aero engine intake may ...

Pneumatic Microballoons for Active Control of the Vibration-Induced Flow
Vibration-induced flow (VIF), in which a mean flow is induced around a microstructure by applying periodic vibrations, is increasingly used as an active flow-control technique at the microscale.

Wind Turbine Gust Load Alleviation with Active Flow Control
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
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

Plasma Synthetic Jet Actuators for Active Flow Control
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
