Numerical simulation of a two-frequency-driven superlattice Faraday-wave pattern
Debashis Panda, Nicolas Périnet, Abdullah M. Abdal +6
The formation of a superlattice pattern in two-frequency-driven Faraday waves discovered and named SSS-I by Arbell & Fineberg (1998, 2002) is investigated by means of Direct Numeri…
Drift, diffusion and divergence
Laurette S. Tuckerman
Turbulent Taylor-Couette flow displays traces of axisymmetric Taylor vortices even at high Reynolds numbers. With this motivation, Feldmann & Avila (2025) carry out long-time numer…
Natural convection in a vertical channel. Part 3. Bifurcations of many (additional) unstable periodic orbits and their dynamical relevance
Zheng Zheng, Laurette S. Tuckerman, Tobias M. Schneider
Vertical thermal convection system exhibits weak turbulence and spatio-temporally chaotic behaviour. In this system, we report seven equilibria and 26 periodic orbits, all new and…
Marangoni-driven patterns, ridges, and hills in surfactant-covered parametric surface waves
Debashis Panda, Lyes Kahouadji, Laurette Tuckerman +4
Parametric oscillations of an interface separating two fluid phases create nonlinear surface waves, called Faraday waves, which organise into simple patterns, like squares and hexa…
Natural convection in a vertical channel. Part 1. Wavenumber interaction and Eckhaus instability in a narrow domain
Zheng Zheng, Laurette S. Tuckerman, Tobias M. Schneider
In a vertical channel driven by an imposed horizontal temperature gradient, numerical simulations have previously shown steady, time-periodic and chaotic dynamics. We explore the o…
Natural convection in a vertical channel. Part 2. Oblique solutions and global bifurcations in a spanwise-extended domain
Zheng Zheng, Laurette S. Tuckerman, Tobias M. Schneider
Vertical thermal convection is a non-equilibrium system in which both buoyancy and shear forces play a role in driving the convective flow. Beyond the onset of convection, the driv…
Phase transition to turbulence via moving fronts
Sébastien Gomé, Aliénor Rivière, Laurette S. Tuckerman +1
Directed percolation (DP), a universality class of continuous phase transitions, has recently been established as a possible route to turbulence in subcritical wall-bounded flows.…
Patterns in transitional shear turbulence. Part 2: Emergence and optimal wavelength
S. Gomé, L. S. Tuckerman, D. Barkley
Low Reynolds number turbulence in wall-bounded shear flows \emph{en route} to laminar flow takes the form of oblique, spatially-intermittent turbulent structures. In plane Couette…
Patterns in transitional shear turbulence. Part 1. Energy transfer and mean-flow interaction
S. Gomé, L. S. Tuckerman, D. Barkley
Low Reynolds number turbulence in wall-bounded shear flows en route to laminar flow takes the form of spatially intermittent turbulent structures. In plane shear flows, these appea…
Extreme events in transitional turbulence
S. Gomé, L. S. Tuckerman, D. Barkley
Transitional localised turbulence in shear flows is known to either decay to an absorbing laminar state or proliferate via splitting. The average passage times from one state to th…
Frequency prediction from exact or self-consistent meanflows
Yacine Bengana, Laurette S. Tuckerman
A number of approximations have been proposed to estimate basic hydrodynamic quantities, in particular the frequency of a limit cycle. One of these, RZIF (for Real Zero Imaginary F…
Statistical transition to turbulence in plane channel flow
Sébastien Gomé, Laurette S. Tuckerman, Dwight Barkley
Intermittent turbulent-laminar patterns characterize the transition to turbulence in pipe, plane Couette and plane channel flows. The time evolution of turbulent-laminar bands in p…
Turbulent cascade, bottleneck and thermalized spectrum in hyperviscous flows
Rahul Agrawal, Alexandros Alexakis, Marc E. Brachet +1
In many simulations of turbulent flows the viscous forces are replaced by a hyper-viscous term in order to suppress the effect of v…
Faraday instability on a sphere: Floquet analysis
Ali-higo Ebo-Adou, Laurette S. Tuckerman
Standing waves appear at the surface of a spherical viscous liquid drop subjected to radial parametric oscillation. This is the spherical analogue of the Faraday instability. Modif…
Faraday instability on a sphere: numerical simulation
Ali-higo Ebo-Adou, Laurette S. Tuckerman, Seungwon Shin +2
We consider a spherical variant of the Faraday problem, in which a spherical drop is subjected to a time-periodic body force, as well as surface tension. We use a full three-dimens…
Spirals and ribbons in counter-rotating Taylor-Couette flow: frequencies from mean flows and heteroclinic orbits
Yacine Bengana, Laurette S. Tuckerman
A number of time-periodic flows have been found to have a property called RZIF: when a linear stability analysis is carried out about the temporal mean (rather than the usual stead…
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…
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…
Universal continuous transition to turbulence in a planar shear flow
Matthew Chantry, Laurette S. Tuckerman, Dwight Barkley
We examine the onset of turbulence in Waleffe flow -- the planar shear flow between stress-free boundaries driven by a sinusoidal body force. By truncating the wall-normal represen…
Turbulent-laminar patterns in shear flows without walls
Matthew Chantry, Laurette S. Tuckerman, Dwight Barkley
Turbulent-laminar intermittency, typically in the form of bands and spots, is a ubiquitous feature of the route to turbulence in wall-bounded shear flows. Here we study the idealis…
Prediction of frequencies in thermosolutal convection from mean flows
Sam E. Turton, Laurette S. Tuckerman, Dwight Barkley
Motivated by studies of the cylinder wake, in which the vortex-shedding frequency can be obtained from the mean flow, we study thermosolutal convection driven by opposing thermal a…
