Large eddy simulations in astrophysics [PDF]
Living 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.

High precision implicit large eddy simulation based on dissipation adaptive adjustment
Kongqi donglixue xuebaoThe implicit large eddy simulation has received widespread attention due to the fact that it does not require additional design to construct the explicit subgrid scale model, but how to regulate its own numerical dissipation such that the numerical ...

Large-eddy simulation of maritime deep tropical convection
Journal of Advances in Modeling Earth Systems, 2009 This study represents an attempt to apply Large-Eddy Simulation (LES) resolution to simulate deep tropical convection in near equilibrium for 24 hours over an area of about 205 x 205 km2, which is comparable to that of a typical horizontal grid cell in a

Large-Eddy Simulation of Wakes of Waked Wind Turbines
Energies, 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 ...

A Surface Flux Estimation Scheme Accounting for Large‐Eddy Effects for Land Surface Modeling
Geophysical Research Letters, 2022 We propose a surface flux estimation formula to account for large eddy effects by keeping the boundary layer depth the only added parameter. We develop a novel way to evaluate the estimation formula by using a set of independent large eddy simulations ...

Defence 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 ...

Journal 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.
