Bistable flow dynamics of airfoil stall under varying angle of attack: A stochastic model with multiplicative noise
Edouard Boujo, Ivan Kharsansky Atallah, Luc R. Pastur
We focus on the intermittent bistable stall dynamics of an airfoil under varying angle of attack. We propose a one-dimensional Langevin equation where the stochastic forcing depend…

On the symmetry-breaking instability of the flow past axisymmetric bluff bodies
A. Chiarini, R. Gauthier, E. Boujo
The primary bifurcation of the flow past three-dimensional axisymmetric bodies is investigated. We show that the azimuthal vorticity generated at the body surface is at the root of…
