Large Eddy Simulation of Yawed Wind Turbine Wake Deformation
Energies, 2022 Wind turbine wake redirection drawn by a yaw control has been proposed as a strategy to improve the performance of wind farms. However, the characteristics and the development of the curled wake structure deformed by the yaw action of the rotor are not ...

Large Eddy Simulation of Combustion for High-Speed Airbreathing Engines
Aerospace, 2022 Large Eddy Simulation (LES) has rapidly developed into a powerful computational methodology for fluid dynamic studies, between Reynolds-Averaged Navier–Stokes (RANS) and Direct Numerical Simulation (DNS) in both accuracy and cost.

Large-eddy simulation of large-scale structures in long channel flow [PDF]
, 2010 We investigate statistics of large-scale structures from large-eddy simulation (LES) of turbulent channel flow at friction Reynolds numbers Re_τ = 2K and 200K (where K denotes 1000).

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 ...

Validation study for Large-Eddy Simulation of Forest Flow [PDF]
E3S Web of Conferences, 2020 The publication presents Large-Eddy Simulation (LES) of flow over a reduced-scale wind tunnel model of a forest canopy. The final aim of the study is to determine factors responsible for damage in forests by strong winds.

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.
