Three-dimensional global stability analysis of turbulent screeching jets
Alessandro Franchini, Nicolas Alferez, Jean-Christophe Robinet
A three dimensional global stability analysis is performed to investigate the problem of screeching jets under turbulent conditions. The study employs an Unsteady Reynolds-Averaged…
Large-scale streak instabilities of transitional channel flow
Nicola Ciola, Yohann Duguet, Jean-Christophe Robinet +2
The emergence of large-scale spatial modulations of turbulent channel flow, as the Reynolds number is decreased, is addressed numerically using the framework of linear stability an…
Modal analysis of the triadic interactions in the dynamics of a transitional shock wave boundary layer interaction
Ismaïl Ben Hassan Saïdi, Stéphane Wang, Guillaume Fournier +2
This work is a numerical study of a transitional shock wave boundary layer interaction (SWBLI). The main goal is to improve our understanding of the well known low-frequency SWBLI…
Krylov methods for large-scale dynamical systems: Application in fluid dynamics
Ricardo S. Frantz, Jean-Christophe Loiseau, Jean-Christophe Robinet
In fluid dynamics, predicting and characterizing bifurcations, from the onset of unsteadiness to the transition to turbulence, is of critical importance for both academic and indus…
Turbulent transition in a channel with superhydrophobic walls: the effect of roughness anisotropy
Antoine Jouin, Stefania Cherubini, Jean-Christophe Robinet
Superhydrophobic surfaces dramatically reduce skin friction of overlying liquid flows. These surfaces are complex and numerical simulations usually rely on models for reducing this…
Collective secondary instabilities: an application to three-dimensional boundary-layer flow
Antoine Jouin, Stefania Cherubini, Jean-Christophe Robinet
In some linearly unstable flows, secondary instability is found to have a much larger wavelength than that of the primary unstable modes, so that it cannot be recovered with a clas…
Numerical investigation of three-dimensional partial cavitation in a Venturi geometry
Camille Gouin, Carlos Junqueira-Junior, Eric Goncalves da Silva +1
Sheet cavitation appears in many hydraulic applicationss and can lead to technical issues. Some fundamental outcomes such as the complex topology of 3-Dimensional cavitation pocket…
Time-stepping and Krylov methods for large-scale instability problems
Jean-Christophe Loiseau, Michele Alessandro Bucci, Stefania Cherubini +1
With the ever increasing computational power available and the development of high-performances computing, investigating the properties of realistic very large-scale nonlinear dyna…
