The phase transition to turbulence in spatially extended shear flows
Lukasz Klotz, Gregoire Lemoult, Kerstin Avila +1
Directed percolation(DP) has recently emerged as a possible solution to the century old puzzle surrounding the transition to turbulence. Multiple model studies reported DP exponent…
The life and fate of a bubble in a geometrically-perturbed Hele-Shaw channel
Antoine Gaillard, Jack S. Keeler, Grégoire Le Lay +4
Motivated by the desire to understand complex transient behaviour in fluid flows, we study the dynamics of an air bubble driven by the steady motion of a suspending viscous fluid w…
The influence of invariant solutions on the transient behaviour of an air bubble in a Hele-Shaw channel
J. S. Keeler, A. B. Thompson, G. Lemoult +2
We hypothesize that dynamical systems concepts used to study the transition to turbulence in shear flows are applicable to other transition phenomena in fluid mechanics. In this pa…
Couette-Poiseuille flow experiment with zero mean advection velocity: Subcritical transition to turbulence
Lukasz Klotz, Grégoire Lemoult, Idalia Frontczak +2
We present a new experimental set-up that creates a shear flow with zero mean advection velocity achieved by counterbalancing the nonzero streamwise pressure gradient by moving bou…
The rise of fully turbulent flow
Dwight Barkley, Baofang Song, Vasudevan Mukund +3
Over a century of research into the origin of turbulence in wallbounded shear flows has resulted in a puzzling picture in which turbulence appears in a variety of different states…
The universality class of the transition to turbulence
Liang Shi, Gregoire Lemoult, Kerstin Avila +3
Turbulence is one of the most frequently encountered non-equilibrium phenomena in nature yet characterising the transition that gives rise to it has remained an elusive task. Altho…
Turbulent spots in channel flow: an experimental study Large-scale flow, inner structure and low order model
Grégoire Lemoult, Konrad Gumowski, Jean-Luc Aider +1
We present new experimental results on the development of turbulent spots in channel flow. The internal structure of a turbulent spot is measured, with Time Resolved Stereoscopic P…
Experimental scaling law for the sub-critical transition to turbulence in plane Poiseuille flow
Grégoire Lemoult, Jean-Luc Aider, José-Eduardo Wesfreid
We present an experimental study of transition to turbulence in a plane Poiseuille flow. Using a well-controlled perturbation, we analyse the flow using extensive Particule Image V…
