The Lagrangian description of turbulence is characterized by a unique conceptual simplicity
and by an immediate connection with the physics of dispersion and mixing. In this article, we …

Using what has become a celebrated catchphrase, Philip W. Anderson once wrote that
“more is different”(Science, Vol. 177, Issue 4047, pp. 393–396, 1972). First formulated in the …

Transport of exhaled droplets and aerosol suspension is a main route for the transmission of
highly infectious respiratory diseases. A poorly ventilated room, where human body heat …

A detailed comparison between data from experimental measurements and numerical
simulations of Lagrangian velocity structure functions in turbulence is presented …

Small flexible fibers in a turbulent flow are found to be as straight as stiff rods most of the
time. This is due to the cooperative action of flexural rigidity and fluid stretching. However …

Motivated by systems in which droplets grow and shrink in a turbulence-driven
supersaturation field, we investigate the problem of turbulent condensation in a general …

We expose a hidden scaling symmetry of the Navier–Stokes equations in the limit of
vanishing viscosity, which stems from dynamical space–time rescaling around suitably …

Point-particle based direct numerical simulation (PPDNS) has been a productive research
tool for studying both single-particle and particle-pair statistics of inertial particles suspended …

An important aspect in numerical simulations of particle-laden turbulent flows is the
interpolation of the flow field needed for the computation of the Lagrangian trajectories. The …

In this paper a general theory for interpolation methods on a rectangular grid is introduced.
By the use of this theory an efficient B-spline-based interpolation method for spectral codes …
