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 ...

A High-Order Variational Multiscale Approach to Turbulence for Compact Nodal Schemes
, 2020 This article presents a formulation that extends the variational multiscale modelling for compressible large-eddy simulation to a vast family of compact nodal numerical methods represented by the high-order flux reconstruction scheme.

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 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
