Tracking stall cell dynamics at high Reynolds numbers
Badoui Hanna, Bérengère Podvin, Caroline Braud
The spanwise organization of the flow over a thick airfoil is investigated using surface pressure measurements for a range of angles of attack around maximum lift and high Reynolds…
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…
Dissipation-based proper orthogonal decomposition of turbulent Rayleigh-Bénard convection flow
Peder Jørgensgaard Olesen, Laurent Soucasse, Bérengère Podvin +1
We present a formulation of proper orthogonal decomposition (POD) producing a velocity-temperature basis optimized with respect to an dissipation norm. This decomposition is…
On the analysis of Rayleigh-Bénard convection using Latent Dirichlet Allocation
Bérengère Podvin, Laurent Soucasse, François Yvon
We apply a probabilistic clustering method, Latent Dirichlet Allocation (LDA), to characterize the largescale dynamics of Rayleigh-Bénard convection. The method, introduced in Frih…
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…
On the relationship between the base pressure and the velocity in the near-wake of an Ahmed body
Bérengère Podvin, Stéphanie Pellerin, Yann Fraigneau +2
We investigate the near-wake flow of an Ahmed body which is characterized by switches between two asymmetric states that are mirrors of each other in the spanwise direction. The wo…
