Passive Flow Control Study in an S-Duct Using Stereo Particle Image Velocimetry

Autor: Pavlos K. Zachos, Geoffrey Tanguy, Daniel Gil-Prieto, David G. MacManus, Eric Garnier

Publikováno v: AIAA Journal
AIAA Journal, American Institute of Aeronautics and Astronautics, 2017, 55 (6), pp.1862-1877. ⟨10.2514/1.J055354⟩

International audience; The ability of vortex generators to reduce the unsteady distortion at the exit plane of an S duct is investigated. The three components of the velocity at the aerodynamic interface plane were measured using a stereo particle v

Interaction between a jet and a turbulent boundary layer

Autor: Laurent Keirsbulck, Célestin Ott, Marc Lippert, Quentin Gallas, Jerome Delva

Publikováno v: AIAA AVIATION 2019
AIAA AVIATION 2019, Jun 2019, DALLAS, United States. ⟨10.2514/6.2019-3501⟩

International audience; Fluidic actuators are at the heart of active flow control. To implement an efficient flow control strategy, it is critical to have a good understanding of how fluidic actuators interact with the flow, especially with the incom

AIAA Aviation 2019 Forum, Jun 2019, Dallas, United States. ⟨10.2514/6.2019-2913⟩

International audience; Two reduced order models of the flow are suggested. The first one is the classical nonlinear Van der Pol oscillator. The second one is the previous Van der Pol oscillator with the pulsation perturbed by a random signal. This y
