Growth dynamics of turbulent spots in plane Couette flow
Marie Couliou, Romain Monchaux
We experimentally and numerically investigate the temporal aspects of turbulent spots spreading in a plane Couette flow for transitional Reynolds numbers between 300 and 450. Spot…
How does turbulence spread in plane Couette flows?
Marie Couliou, Romain Monchaux
We investigate the growth in the spanwise direction of turbulent spots invading a laminar flow in a plane Couette flow. Direct Numerical Simulation is used to track the nucleation…
Large scale flows in transitional plane Couette flow: a key ingredient of the spot growth mechanism
M. Couliou, R. Monchaux
Using Particle Image Velocimetry (PIV) in a new experimental plane Couette flow, we investigate the dynamics of turbulent patches invading formerly laminar flows. We evidence exper…
Do finite size neutrally buoyant particles cluster?
Lionel Fiabane, Romain Volk, Jean-Francois Pinton +3
We investigate the preferential concentration of particles which are neutrally buoyant but with a diameter significantly larger than the dissipation scale of the carrier flow. Such…
Statistical mechanics of Beltrami flows in axisymmetric geometry: Theory reexamined
Aurore Naso, Romain Monchaux, Pierre-Henri Chavanis +1
A simplified thermodynamic approach of the incompressible axisymmetric Euler equations is considered based on the conservation of helicity, angular momentum and microscopic energy.…
Characterization of turbulence in inhomogeneous anisotropic flows
Pierre-Philippe Cortet, Pantxo Diribarne, Romain Monchaux +3
We introduce a global quantity that characterizes turbulent fluctuations in inhomogeneous anisotropic flows. This time-dependent quantity is based on spatial averages of global…
