Large eddy simulations in astrophysics [PDF]

open access: yesLiving Reviews in Computational Astrophysics, 2015
Abstract In this review, the methodology of large eddy simulations (LES) is introduced and applications in astrophysics are discussed. As theoretical framework, the scale decomposition of the dynamical equations for compressible neutral fluids by means of spatial filtering is explained.

Monte Carlo Spectral Integration: a Consistent Approximation for Radiative Transfer in Large Eddy Simulations

open access: yesJournal of Advances in Modeling Earth Systems, 2009
Large-eddy simulation (LES) refers to a class of calculations in which the large energy-rich eddies are simulated directly and are insensitive to errors in the modeling of sub-grid scale processes.

Large Eddy Simulation

open access: yesDefence Science Journal, 2010
Large eddy simulation (LES) is an emerging technique for obtaining an approximation to turbulent flow fields It is an improvement over the widely prevalent practice of obtaining means of turbulent flows when the flow has large scale, low frequency, unsteadiness An introduction to the method, its general formulation, and the more common modelling for ...

Large-Eddy Simulation of Wakes of Waked Wind Turbines

open access: yesEnergies, 2022
The wake dynamics of a wind turbine are influenced by the atmospheric turbulence and the wake of its upwind turbine. In this work, we investigate the wake characteristics of a waked wind turbine for four different downwind spacings and three different ...

Large-Eddy Simulation of Contrails [PDF]

open access: yesJournal of the Atmospheric Sciences, 1998
Numerical simulations of contrails have been performed to investigate the role of various external parameters and physical processes in the life cycle of contrails. The general idea underlying the model is that of a largeeddy model. The model explicitly represents the large-scale three-dimensional motions (10-m grid resolution), while small-scale ...
