On the rheoscopic measurement of turbulent decay in wall-bounded flows
Tao Liu, Victoria Nicolazo-Crach, Ramiro Godoy-Diana +2
Quench experiments where the flow passes from a fully turbulent state to a laminar state by an abrupt decrease in the flow Reynolds number () have been extensively studied in t…
Waviness and self-sustained turbulence in plane Couette-Poiseuille flow
Manuel Etchevest, Pablo Dmitruk, Supriya Karmakar +3
Direct numerical simulations of a Couette Poiseuille flow were performed near the transition to turbulence to investigate the nonlinear relationship between streak waviness and rol…
Discovery of propagating trains of oscillons over Faraday waves in a 1D experiment
Samantha Kucher, José Eduardo Wesfreid, Pablo Javier Cobelli
We report the discovery of highly localized structures traveling over a one-dimensional pattern of Faraday waves in a vertically-vibrated fluid layer confined in a thin annular cel…
Lift-up and streak waviness drive the self-sustained process in wall-bounded transition to turbulence
Tao Liu, Benoît Semin, Ramiro Godoy-Diana +1
Flow field measurements from a Couette-Poiseuille experiment are used to examine quantitatively certain steps of the self-sustained process (SSP) of wall-bounded transition to turb…
Experiments on a jet in a crossflow in the low-velocity-ratio regime
Lukasz Klotz, Konrad Gumowski, Jose Eduardo Wesfreid
The hairpin instability of a jet in a crossflow (JICF) for a low jet-to-crossflow velocity ratio is investigated experimentally for a velocity ratio range of and…
The Self-Sustaining Process in Taylor-Couette Flow
Tommy Dessup, Laurette S. Tuckerman, Jose Eduardo Wesfreid +2
The transition from Tayor vortex flow to wavy-vortex flow is revisited. The Self-Sustaining Process (SSP) of Waleffe [Phys. Fluids 9, 883-900 (1997)] proposes that a key ingredient…
