Qualitative dynamics of wavepackets in turbulent jets
Onofrio Semeraro, Francois Lusseyran, Luc Pastur +1
It has long been established that turbulent jets comprise large-scale coherent structures, now more commonly referred to as "wavepackets". These structures exhibit a remarkable spa…
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…
