New equation for lagrangian incompressible fluid flows applied to turbulence
Olivier Poujade
Theoretical developments in the field of Lagrangian turbulence are made difficult by the fact that equations governing the evolution of lagrangian flows are implicit contrary to eu…
Late-time growth rate, mixing and anisotropy in the multimode narrowband Richtmyer--Meshkov Instability: the -Group Collaboration
B. Thornber, J. Griffond, O. Poujade +17
Turbulent Richtmyer--Meshkov instability (RMI) is investigated through a series of high resolution three dimensional smulations of two initial conditions with eight independent cod…
New radiographic image processing tested on the simple and double-flux platform at OMEGA
Olivier Poujade, Michel Ferri, Isabelle Geoffray
Ablation fronts and shocks are two radiative/hydrodynamic features ubiquitous in inertial confinement fusion (ICF). A specially designed shock-tube experiment was tested on the OME…
Radiative ablation with two ionizing-fronts when opacity displays a sharp absorption edge
Olivier Poujade, Max Bonnefille, Marc Vandenboomgaerde
The interaction of a strong flux of photons with matter through an ionizing-front (I-front) is an ubiquitous phenomenon in the context of astrophysics and inertial confinement fusi…
Growth rate of Rayleigh-Taylor turbulent mixing layers with the foliation approach
Olivier Poujade, Mathieu Peybernes
For years, astrophysicists, plasma fusion and fluid physicists have puzzled over Rayleigh-Taylor turbulent mixing layers. In particular, strong discrepancies in the growth rates ha…
Rayleigh-Taylor turbulence is nothing like Kolmogorov turbulence in the self similar regime
Olivier Poujade
An increasing number of numerical simulations and experiments describing the turbulent spectrum of Rayleigh-Taylor (RT) mixing layers came to light over the past few years. Results…
