Large eddy simulation of sediment transport over rippled beds [PDF]
Nonlinear Processes in Geophysics, 2014 Wave-induced boundary layer (BL) flows over sandy rippled bottoms are studied using a numerical model that applies a one-way coupling of a "far-field" inviscid flow model to a "near-field" large eddy simulation (LES) Navier–Stokes (NS) model.

A Coherent vorticity preserving eddy viscosity correction for Large-Eddy Simulation
, 2017 This paper introduces a new approach to Large-Eddy Simulation (LES) where subgrid-scale (SGS) dissipation is applied proportionally to the degree of local spectral broadening, hence mitigated or deactivated in regions dominated by large-scale and/or ...

Large-Eddy Simulation Analyses of Heated Urban Canyon Facades
Energies, 2021 Thermal convective flows are common phenomena in real urban canyons and strongly affect the mechanisms of pollutant removal from the canyon. The present contribution aims at investigating the complex interaction between inertial and thermal forces within

Advanced Engineering Materials, EarlyView.The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

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 ...
