When discussing research in physics and in science more generally, it is common to ascribe
equal importance to the three components of the scientific trinity: theoretical, experimental …

When very small particles are suspended in a fluid in motion, they tend to follow the flow.
How such tracer particles are mixed, transported, and dispersed by turbulent flow has been …

Multiscale statistical analyses of inertial particle distributions are presented to investigate the
statistical signature of clustering and void regions in particle-laden incompressible isotropic …

Physical properties of clusters, ie systems composed of a 'small'number of particles, are
qualitatively different from those of infinite systems. The general approach to the problem of …

Inertial particle data from three-dimensional direct numerical simulations of particle-laden
homogeneous isotropic turbulence at high Reynolds number are analysed using Voronoi …

Direct numerical simulation of homogeneous isotropic turbulence shows pronounced
clustering of inertial particles in the inertial subrange at high Reynolds number, in addition to …

This study conducts a comprehensive analysis of the Fourier spectra characteristics of
particle preferential concentration in turbulent flows obtained by Eulerian and Lagrangian …

Small solid particles, droplets, and bubbles can form clusters in turbulent flows by the action
of coherent vortices. This phenomenon, sometimes called the preferential concentration …

An expected statistical law of passive scalar turbulence subjected to high Schmidt numbers
is studied with the Hessian-based Lagrangian renormalized approximation (HBLRA), a self …

A single-time two-point spectral closure is developed by approximation of the Lagrangian
direct interaction approximation (LDIA) for a passive scalar in the presence of a mean scalar …
