High-speed imaging is in popular demand for a broad range of experiments in fluids. It
allows for a detailed visualization of the event under study by acquiring a series of image …

Direct numerical simulation of the gravity-induced settling of finite-size particles in triply
periodic domains has been performed under dilute conditions. For a single solid-to-fluid …

The gravity-driven motion of rigid particles in a viscous fluid is relevant in many natural and
industrial processes, yet this has mainly been investigated for spherical particles. We …

Experiments on the flow around stationary circular cylinders with very low aspect ratio
piercing the water free surface were carried out in a recirculating water channel. Eight …

This paper reports on an experimental study of the motion of freely rising axisym-metric rigid
bodies in a low-viscosity fluid. We consider flat cylinders with height h smaller than the …

The periodic coupled wakes of two spheres, placed side by side in a uniform stream at low
Reynolds numbers, are studied experimentally and by Direct Numerical Simulations …

The global dynamics of open shear flows is closely related to the nature of their local
instability characteristics, either convective or absolute. The present investigation revisits the …

We investigate the stability properties and flow regimes of laminar wakes behind slender
cylindrical bodies, of diameter D and length L, with a blunt trailing edge at zero angle of …

A fully three-dimensional linear stability analysis is carried out to investigate the unstable
bifurcations of a compressible viscous fluid past a sphere. A time-stepper technique is used …

This paper presents the results of an experimental investigation aimed at verifying some of
the interesting conclusions of the numerical study by Jenny et al. concerning the instability …
