New Journal of Physics, 2018 In statistically stationary conditions, the turbulent energy spectrum in a high Reynolds number flow exhibits a k ^−5/3 (Kolmogorov) regime, with a faster decay at larger, dissipative wavenumbers.

Fluids, 2023 Bubble columns (BCs) are widely used in the chemical industry. In many industrial applications, these important gas-liquid contactors operate in a churn-turbulent flow regime.

Diffusional growth of cloud droplets in homogeneous isotropic turbulence: DNS, scaled-up DNS, and stochastic model [PDF]
Atmospheric Chemistry and Physics, 2020 This paper presents a novel methodology to use direct numerical simulation (DNS) to study the impact of isotropic homogeneous turbulence on the condensational growth of cloud droplets.

Velocity autocorrelations of decaying isotropic homogeneous turbulence [PDF]
, 1995 Velocity autocorrelations and the mean-square displacements of fluid particles are obtained for decaying, isotropic homogeneous turbulence by numerical simulation of the flow field, using 1283 and 2563 grids, and tracking several tens of thousands of ...

Fluids, 2019 Incompressible magnetohydrodynamic (MHD) turbulence under influences of the Hall and the gyro-viscous terms was studied by means of direct numerical simulations of freely decaying, homogeneous and approximately isotropic turbulence.

Turbulence decay in the density-stratified intracluster medium
, 2019 Turbulence evolution in a density-stratified medium differs from that of homogeneous isotropic turbulence described by the Kolmogorov picture. We evaluate the degree of this effect in the intracluster medium (ICM) with hydrodynamical simulations. We find

Fluctuation-Dissipation Relations and statistical temperatures in a turbulent von K\'arm\'an flow [PDF]
, 2008 We experimentally characterize the fluctuations of the non-homogeneous non-isotropic turbulence in an axisymmetric von K\'arm\'an flow. We show that these fluctuations satisfy relations analogous to classical Fluctuation-Dissipation Relations (FDRs) in ...

On Modelling Wind-Farm Wake Turbulence Autospectra and Coherence from a Database
Energies, 2018 This study addresses the feasibility of modeling wind-farm wake-turbulence autospectra and coherences from a database: flow velocity points from experimental and computational fluid dynamics (CFD) investigations. Specifically, it first applies an earlier-

Radar cross sections for mesospheric echoes at Jicamarca [PDF]
Annales Geophysicae, 2009 Radar cross sections (RCS) of mesospheric layers at 50 MHz observed at Jicamarca, Peru, range from 10−18 to 10−16 m−1, three orders of magnitudes smaller than cross sections reported for polar mesospheric winter echoes during solar ...
