Statistical ensemble of large-eddy simulations [PDF]
Journal of Fluid Mechanics, 2002 A statistical ensemble of large-eddy simulations (LES) is run simultaneously for the same flow. The information provided by the different large-scale velocity fields is used in an ensemble-averaged version of the dynamic model. This produces local model parameters that only depend on the statistical properties of the flow.

Advances in Mechanical Engineering, 2016 For pump–turbines, most of the instabilities couple with high-level pressure fluctuations, which are harmful to pump–turbines, even the whole units. In order to understand the causes of pressure fluctuations and reduce their amplitudes, proper numerical ...

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.

Modeling of Breaching-Generated Turbidity Currents Using Large Eddy Simulation
Journal 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 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

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

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 ...
