Direct numerical simulation: a tool in turbulence research

P Moin, K Mahesh - Annual review of fluid mechanics, 1998 - annualreviews.org
▪ Abstract We review the direct numerical simulation (DNS) of turbulent flows. We stress that
DNS is a research tool, and not a brute-force solution to the Navier-Stokes equations for …

The star formation rate of turbulent magnetized clouds: comparing theory, simulations, and observations

C Federrath, RS Klessen - The Astrophysical Journal, 2012 - iopscience.iop.org
The role of turbulence and magnetic fields is studied for star formation in molecular clouds.
We derive and compare six theoretical models for the star formation rate (SFR)—the …

The sonic scale of interstellar turbulence

C Federrath, RS Klessen, L Iapichino, JR Beattie - Nature Astronomy, 2021 - nature.com
Understanding the physics of turbulence is crucial for many applications, including weather,
industry and astrophysics. In the interstellar medium,, supersonic turbulence plays a crucial …

Settling velocity and concentration distribution of heavy particles in homogeneous isotropic turbulence

LP Wang, MR Maxey - Journal of fluid mechanics, 1993 - cambridge.org
The average settling velocity in homogeneous turbulence of a small rigid spherical particle,
subject to a Stokes drag force, has been shown to differ from that in still fluid owing to a bias …

Preferential concentration of particles by turbulence

KD Squires, JK Eaton - Physics of Fluids A: Fluid Dynamics, 1991 - pubs.aip.org
Direct numerical simulation of isotropic turbulence was used to investigate the effect of
turbulence on the concentration fields of heavy particles. The hydrodynamic field was …

Subgrid-scale model for large-eddy simulation of isotropic turbulent flows using an artificial neural network

Z Zhou, G He, S Wang, G Jin - Computers & Fluids, 2019 - Elsevier
An artificial neural network (ANN) is used to establish the relation between the resolved-
scale flow field and the subgrid-scale (SGS) stress tensor, to develop a new SGS model for …

Comparing the statistics of interstellar turbulence in simulations and observations-Solenoidal versus compressive turbulence forcing
