Stall cells over an airfoil. Part 2: A vortex-based analytical model for their formation and saturation
Rishabh Mishra, Emmanuel Guilmineau, Ingrid Neunaber +1
Stall cells are spanwise-periodic flow structures that spontaneously form on airfoils operating near stall, fundamentally altering the aerodynamic loading distribution. Despite dec…
Stall cells over an airfoil. Part 1: Three-dimensional flow organisation and vorticity dynamics
Rishabh Mishra, Emmanuel Guilmineau, Ingrid Neunaber +1
This study investigates the three-dimensional organisation and evolution of stall cells in the separated flow region over an airfoil. Using a hybrid RANS/LES approach based on the…
Sparse surface pressure-based reconstruction of the flow around a thick airfoil over a range of angles of attack
Quentin Bucquet, Bérengère Podvin, Caroline Braud +1
We present an efficient neural-based approach to estimate the instantaneous flow field around an airfoil from limited surface pressure measurements. The model, denoted SNN-POD, rel…
Study of the wall pressure variations on the stall inception of a thick cambered profile at high Reynolds number
Caroline Braud, Bérengère Podvin, Julien Deparday
We present an experimental study of the aerodynamic forces on a thick and cambered airfoil at a high Reynolds number 3.6 x 10^6, which is of direct relevance for wind turbine desig…
Ability of the e-TellTale sensor to detect flow features over wind turbine blades: flow separation/reattachment dynamics
A. Soulier, C. Braud, D. Voisin +1
Monitoring the flow features over wind turbine blades is a challenging task that has become more and more crucial. This paper is devoted to demonstrate the ability of the e-TellTal…
Robust and fast online identification of streamwise vortices properties for closed-loop control purposes
Caroline Braud, Alex Liberzon
We propose to combine the active vortex generators with the particle image velocimetry (PIV) measurements and post-processing streamwise vortex characterization algorithms into a f…
