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…
Proper Orthogonal Decomposition Analysis and Modelling of the wake deviation behind a squareback Ahmed body
Berengère Podvin, Stéphanie Pellerin, Yann Fraigneau +2
We investigate numerically the 3-D flow around a squareback Ahmed body at Reynolds number Re = 104. Proper Orthogonal Decomposition (POD) is applied to a symmetry-augmented databas…
Stochastic modelling of a freely rotating disk facing a uniform flow
E. Boujo, O. Cadot
The fluid-structure interaction between a thin circular disk and its turbulent wake is investigated experimentally and described with a low-order stochastic model. The disk faces a…
Phenomenological model for predicting stationary and non-stationary spectra of wave turbulence in vibrating plates
T. Humbert, C. Josserand, C. Touzé +1
A phenomenological model describing the time-frequency dependence of the power spectrum of thin plates vibrating in a wave turbulence regime, is introduced. The model equation cont…
Wave turbulence in vibrating plates : the effect of damping
Thomas Humbert, Olivier Cadot, Gustavo Düring +3
The effect of damping in the wave turbulence regime for thin vibrating plates is studied. An experimental method, allowing measurements of dissipation in the system at all scales,…
Statistics of power injection in a plate set into chaotic vibration
Olivier Cadot, Arezki Boudaoud, Cyril Touzé
A vibrating plate is set into a chaotic state of wave turbulence by either a periodic or a random local forcing. Correlations between the forcing and the local velocity response of…
