Our work focuses on the sweep-stick mechanism of particle clustering in turbulent flows
introduced by Chen et al.[L. Chen, S. Goto, and JC Vassilicos,“Turbulent clustering of …

In this paper, we consider the physical mechanism for the clustering of inertial particles in
the inertial range of isotropic turbulence. We analyze the exact, but unclosed, equation …

Despite the widely acknowledged significance of turbulence-driven clustering, a clear
topological definition of particle cluster in turbulent dispersed multiphase flows has been …

Clustering of inertial particles in fully developed two-dimensional inverse cascading
turbulence occurs for all particle relaxation times ranging from an order of magnitude under …

We have performed interface-resolved direct numerical simulations of forced homogeneous-
isotropic turbulence in a dilute suspension of spherical particles in the Reynolds number …

Inertial particles, ie, small heavy particles, can inhomogeneously distribute and form clusters
even in statistically homogeneous turbulence. When the Reynolds number of turbulence is …

In high-Reynolds-number two-dimensional turbulence with a− 5/3 power-law energy
spectrum, the clustering of inertial particles reflects the clustering of acceleration stagnation …

An asymptotic solution is derived for the motion of inertial particles exposed to Stokes drag
in an unsteady random flow. This solution provides an estimate for the sum of Lyapunov …

It is proposed that the inertial range clustering of small heavy particles in fluid turbulence
occurs as a result of the sweep-stick mechanism which causes inertial particles to cluster so …

Expanding recent observations by Hammond & Meng (J. Fluid Mech., vol. 921, 2021, A16),
we present a range of detailed experimental data of the radial distribution function (rdf) of …
