The tailbud is the posterior leading edge of the growing vertebrate embryo and consists of
motile progenitors of the axial skeleton, musculature and spinal cord. We measure the 3D …

We report the experimental observation of Richardson dispersion and a double cascade in a
thin horizontal fluid flow induced by Faraday waves. The energy spectra and the mean …

We present a jointed experimental and numerical study examining the influence of vortical
structures on the settling of solid spherical particles under the action of gravity at low Stokes …

Surfzone eddies enhance the dispersion and transport of contaminants, bacteria, and larvae
across the nearshore, altering coastal water quality and ecosystem health. During …

In nature, turbulent flows exist that are neither simply 2D nor 3D but are forced towards one
state or the other by boundary conditions such as varying stratification. Here, we report the …

We report the interaction between active non-spherical swimmers and a long-standing flow
structure, Lagrangian coherent structures (LCSs), in a weakly turbulent two-dimensional …

We present a combined experimental and theoretical study of the primary and secondary
instabilities in a Kolmogorov-like flow. The experiment uses electromagnetic forcing with an …

Using filter-space techniques, we study the scale-to-scale transport of energy in a quasi-two-
dimensional, weakly turbulent fluid flow averaged along the trajectories of fluid elements …

Turbulence in two-dimensional flows is expected to produce a dynamical state in which
energy condenses into the largest scale allowed by the system when the scale at which …

Using filter-space techniques (FSTs), we study the spatial structure of the scale-to-scale flux
of energy in two-dimensional flow. Analysing data from a weakly turbulent, experimental …
