Evaluating Terrain as a Turbulence Generation Method
Energies, 2021 When driving microscale large-eddy simulations with mesoscale model solutions, turbulence will take space to develop, known as fetch, on the microscale domain.

Comparison of Subgrid-scale Viscosity Models and Selective Filtering Strategy for Large-eddy Simulations [PDF]
, 2013 Explicitly filtered large-eddy simulations (LES), combining high-accuracy schemes with the use of a selective filtering without adding an explicit subgrid-scales (SGS) model, are carried out for the Taylor-Green-vortex and the supersonic-boundary-layer ...

Localization of unresolved regions in the selective large-eddy simulation of hypersonic jets [PDF]
, 2010 A method for the localization of the regions where the turbulent fluctuations are unresolved is applied to the selective large-eddy simulation (LES) of a compressible turbulent jet of Mach number equal to 5.

Large eddy simulation using high-resolution and high-order methods [PDF]
, 2009 Restrictions on computing power make direct numerical simulation too expensive for complex flows; thus, the development of accurate large eddy simulation (LES) methods, which are industrially applicable and efficient, is required.

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.
