Large eddy simulation of sediment transport over rippled beds [PDF]

open access: yesNonlinear 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.

Modeling of Breaching-Generated Turbidity Currents Using Large Eddy Simulation

open access: yesJournal of Marine Science and Engineering, 2020
Breaching flow slides result in a turbidity current running over and directly interacting with the eroding, submarine slope surface, thereby promoting further sediment erosion. The investigation and understanding of this current are crucial, as it is the

Large Eddy Simulation of stratified flows over structures

open access: yesEPJ Web of Conferences, 2013
We tested the ability of the LES model CLMM (Charles University Large-Eddy Microscale Model) to model the stratified flow around three dimensional hills.

A Coherent vorticity preserving eddy viscosity correction for Large-Eddy Simulation

open access: yes, 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 ...

Eddy heat fluxes from direct current measurements of the Antarctic Polar Front in Shag Rocks Passage [PDF]

open access: yes, 2008
Determining meridional heat flux in the Southern Ocean is critical to the accurate understanding and model simulation of the global ocean. Mesoscale eddies provide a significant but poorly-defined contribution to this transport.

Large-eddy simulation of maritime deep tropical convection

open access: yesJournal 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

A Surface Flux Estimation Scheme Accounting for Large‐Eddy Effects for Land Surface Modeling

open access: yesGeophysical 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 ...

Large-Eddy Simulation Analyses of Heated Urban Canyon Facades

open access: yesEnergies, 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
