Large scale flow around turbulent spots
M. Lagha, P. Manneville
Numerical simulations of a model of plane Couette flow focusing on its in-plane spatio-temporal properties are used to study the dynamics of turbulent spots.
Modeling transitional plane Couette flow
M. Lagha, P. Manneville
The Galerkin method is used to derive a realistic model of plane Couette flow in terms of partial differential equations governing the space-time dependence of the amplitude of a f…
Understanding the sub-critical transition to turbulence in wall flows
Paul Manneville
Contrasting with free shear flows presenting velocity profiles with inflection points which cascade to turbulence in a relatively mild way, wall bounded flows are deprived of (iner…
Laminar-turbulent boundary in plane Couette flow
Tobias M Schneider, John F Gibson, Maher Lagha +2
We apply the iterated edge state tracking algorithm to study the boundary between laminar and turbulent dynamics in plane Couette flow at Re=400. Perturbations that are not strong…
Bubble effect on Kelvin-Helmholtz' instability
Sergey L. Gavrilyuk, Henri Gouin, Vladimir M. Teshukov
We derive boundary conditions at interfaces (contact discontinuities) for a class of Lagrangian models describing, in particular, bubbly flows. We use these conditions to study Kel…
