New estimations of the added mass and damping of two cylinders vibrating in a viscous fluid, from theoretical and numerical approaches
Romain Lagrange, Yann Fraigneau
This paper deals with the small oscillations of two circular cylinders immersed in a viscous stagnant fluid. A new theoretical approach based on an Helmholtz expansion and a bipola…
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…
Spatio-temporal Proper Orthogonal Decomposition of turbulent channel flow
Srikanth Derebail Muralidhar, Bérengère Podvin, Lionel Mathelin +1
An extension of Proper Orthogonal Decomposition is applied to the wall layer of a turbulent channel flow (Re τ = 590), so that empirical eigenfunctions are defined in both space an…
From linear stability analysis to three-dimensional organisation in an incompressible open cavity flow
L. R. Pastur, Y. Fraigneau, F. Lusseyran +1
Three-dimensional direct numerical simulations of an incompressible open square cavity flow are conducted. Features of the permanent (non-linear) regime together with the linear st…
Determining the Spectral Signature of Spatial Coherent Structures
L. R. Pastur, F. Lusseyran, Y. Fraigneau +1
We applied to an open flow a proper orthogonal decomposition (pod) technique, on 2D snapshots of the instantaneous velocity field, to reveal the spatial coherent structures respons…
