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.

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.

Lagrangian cascade in three-dimensional homogeneous and isotropic turbulence [PDF]
Journal of Fluid Mechanics, 2014 AbstractIn this work, the scaling statistics of the dissipation along Lagrangian trajectories are investigated by using fluid tracer particles obtained from a high-resolution direct numerical simulation with $\mathit{Re}_{\lambda }=400$. Both the energy dissipation rate $\epsilon $ and the local time-averaged $\epsilon _{\tau }$ agree rather well with ...

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 ...

On the self-similarity of line segments in decaying homogeneous isotropic turbulence [PDF]
Computers & Fluids, 2018 The self-similarity of a passive scalar in homogeneous isotropic decaying turbulence is investigated by the method of line segments (M. Gauding et al., Physics of Fluids 27.9 (2015): 095102).

AtmosphereHomogeneous isotropic turbulence (HIT) has been a useful theoretical concept for more than fifty years of theory, modelling, and calculations. Some exact results are revisited in incompressible HIT, with special emphasis on the 4/5 Kolmogorov law.

On the influence of forced homogeneous-isotropic turbulence on the settling and clustering of finite-size particles [PDF]
Acta Mechanica, 2018 We investigate the motion of heavy particles with a diameter of several multiples of the Kolmogorov length scale in the presence of forced turbulence and gravity, resorting to interface-resolved direct numerical simulation based on an immersed boundary ...

An overview of Millionschikov's quasi-normality hypothesis applied to turbulence
International Journal of Applied Mechanics and Engineering, 2014 In this paper, we examine the zero-fourth cumulant approximation that was applied to fluctuating velocity components of homogeneous and isotropic turbulence by M.D. Millionschikov.
