abstract The output from a direct numerical simulation (DNS) of turbulent channel flow at Re
τ≈ 1000 is used to construct a publicly and Web services accessible, spatio-temporal …

We investigate the transport of size-selected particles suspended in turbulent boundary
layers at friction Reynolds numbers up to. These are imaged simultaneously with the flow …

We investigate the behaviour of microscopic heavy particles settling in homogeneous air
turbulence. The regimes are relevant to the airborne transport of dust and droplets: the …

The statistics of the velocity gradient tensor field, which is used to validate the stochastic
estimation and provide insights towards the model's refinement. Jointly, these approaches …

The invariants of the velocity gradient tensor, plane are shown to be independent of the
intensity of the events, and of the same order of magnitude as those in the …

We investigate the late-time Richtmyer–Meshkov instability (RMI) growth of sinuous
perturbations on an air/sulphur hexafluoride interface (Atwood number,(invariants of the …

The small-scale velocity gradient is connected to fundamental properties of turbulence at the
large scales. By neglecting the viscous and non-local pressure Hessian terms, we derive a …

We use high-resolution velocity measurements in a jet-stirred zero-mean-flow facility to
investigate the topology and energy transfer properties of homogeneous turbulence over the …

The dynamics of small-scale structures in free-surface turbulence is crucial to large-scale
phenomena in natural and industrial environments. Here we conduct experiments on the …

In a channel flow, the velocity fluctuations are inhomogeneous and anisotropic. Yet, the
small-scale properties of the flow are expected to behave in an isotropic manner in the very …
