Passive Flow Control Applied to a NACA23012 Airfoil In A Subsonic Flow

33rd AIAA Applied Aerodynamics Conference, 2015
Aerodynamic subsonic flows are an important flow regime for the aeronautical/aerospace industry. Recent studies by the author have shown that the use of an active flow control device, that of a localised asymmetrically located synthetic jet, can significantly improve the aerodynamic performance of bluff and streamlined bodies by altering the three ...

Square cylinder with passive flow control

2017
In the present paper it is presented the flow around a 2D square cylinder which is located downstream of a splitter plate and at a certain distance of it. The fluid velocity below and above the splitter plate is different, several velocity ratios are considered, it is interesting to see that the downstream vortex shedding frequency and amplitude highly

Active and passive flow control on a precessing jet

Experiments in Fluids, 2015
A precessing jet nozzle with water as the working fluid is investigated under passive and active flow control. The actuation effectiveness of 12 microjets around the nozzle inlet for active control of the precessing jet is the focus of this work. Passive control is also applied by modifying the geometry of the precessing jet either by adding a center ...

Passive Multiscale Flow Control by Fractal Grids

2008
Wind tunnel grid-generated turbulence based on a fractal square motif has been studied via hot-wire anemometry, at several free-stream velocities. The aim of the exercise was to see whether a fractal motif could enable multiscale flow control such that the ‘objective functions’ are the nature of the turbulence decay and its non-dimensional turbulence ...

Passive and Active Control of Radiative Heat Flow

2019
Materials that control the absorption and emission of thermal radiation have attracted renewed interest for energy applications. Materials of interest include those with static optical properties that vary with photon wavelength in a desired manner as well as those with dynamic properties that can be actively tuned by external stimuli.

Study of the passive flow control in aerodynamic devices

2018
To study different passive flow control mechanisms for delay separation and increase the performance of aerodynamic devices by means of CFD techniques. The idea behind flow control is to improve aerodynamic performance of air and ground  vehicles and reduce the drag.
