The statistical geometry of dispersing Lagrangian clusters of four particles (tetrahedra) is
studied by means of high-resolution direct numerical simulations of three-dimensional …

Turbulent flows disperse Lagrangian particles resulting in the growth of pairwise separations
and, for sets of three or more particles, in a nontrivial dynamics of their configuration. The …

As three particles are advected by a turbulent flow, they separate from each other and
develop nontrivial geometries, which effectively reflect the structure of the turbulence. We …

We discuss a series of numerical experiments on the dispersion of neutrally buoyant
particles in two-dimensional turbulent flows. The topology of two-dimensional turbulence is …

The evolution in size and shape of three and four-particle clusters (triangles and tetrads,
respectively) in isotropic turbulence is studied using direct numerical simulations at grid …

A computationally efficient model is introduced to account for the sub-grid scale velocities of
tracer particles dispersed in statistically homogeneous and isotropic, incompressible …

The statistics of Lagrangian particles transported by a three-dimensional fully developed
turbulent flow is investigated by means of high-resolution direct numerical simulations. The …

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

Two-particle dispersion is of central importance to a wide range of natural and industrial
applications. It has been an active area of research since seminal paper. This review …

Preferential concentration of inertial particles in turbulent flow is studied by high resolution
direct numerical simulations of two-dimensional turbulence. The formation of network-like …
