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).

MATEC Web of Conferences, 2015 Numerical simulation is the main method to solve turbulence problems. As one of the three methods which are commonly used in large-eddy simulation model (LES) is the most effective and promising research method. The basic idea of large-eddy simulation is

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.

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
