Aging and memory of transitional turbulence [PDF]
Nature CommunicationsThe recent classification of the onset of turbulence as a directed percolation (DP) phase transition has been applied to all major shear flows including pipe, channel, Couette and boundary layer flows.

Transition to turbulence in shear flows [PDF]
Physica A: Statistical Mechanics and Its Applications, 2018 Pipe flow and many other shear flows show a transition to turbulence at flow rates for which the laminar profile is stable against infinitesimal perturbations. In this brief review the recent progress in the understanding of this transition will be summarized, with a focus on the linear and nonlinear states that drive the transitions, the extended and ...

Anisotropic fluctuations in turbulent shear flows [PDF]
Physics of Fluids, 2004 An experimental analysis of small-scale anisotropic fluctuations has been performed in two different flows in order to assess possible universal features of shear dominated turbulence, such as the decay rate of anisotropy at small scales and the recovery of isotropy.

Impact of turbulence on aeolian particle entrainment: results from wind-tunnel experiments [PDF]
Atmospheric Chemistry and Physics, 2022 We hypothesize that large eddies play a major role in the entrainment of aeolian particles. To test this, wind-tunnel experiments are carried out to measure the particle entrainment rate for various sizes and flow conditions.

Transition to turbulence in a shear flow
Physical Review E, 1999 We analyze the properties of a 19 dimensional Galerkin approximation to a parallel shear flow. The laminar flow with a sinusoidal shape is stable for all Reynolds numbers Re. For sufficiently large Re additional stationary flows occur; they are all unstable.
