Fluid dynamics turbulence refers to the chaotic and unpredictable dynamics of flows.
Despite the fact that the equations governing the motion of fluids are known since more than …

The problem of anisotropy and its effects on the statistical theory of high Reynolds number
(Re) turbulence (and turbulent transport) is intimately related and intermingled with the …

Since its discovery,, the deep-sea glass sponge Euplectella aspergillum has attracted
interest in its mechanical properties and beauty. Its skeletal system is composed of …

The formation and amplification of streamwise velocity perturbations induced by cross-
stream disturbances is ubiquitous in shear flows. This disturbance growth mechanism, so …

Particulate flows have mainly been studied under the simplifying assumption of a one-way
coupling regime where the disperse phase does not modify the carrier fluid. A more …

The objective of the paper is to present a statistical model for predicting pair dispersion and
preferential concentration of particles suspended in an isotropic homogeneous turbulent …

Real turbulent flows are difficult to classify as either spatially homogeneous or isotropic.
Nonetheless these idealizations allow the identification of certain universal features …

The three-dimensional vortex clusters, and the structures based on the quadrant
classification of the intense tangential Reynolds stress (Qs), are studied in direct numerical …

Turbulent fluctuations induce the common phenomenon known as clustering in the spatial
arrangement of small inertial particles transported by the fluid. Particles spread non …

Statistically stationary and homogeneous shear turbulence (SS-HST) is investigated by
means of a new direct numerical simulation code, spectral in the two horizontal directions …
