Accurate microscale windfields computations over complex topography is crucial to many particle transport models but remains a challenging task. The objective of this work focuses on the numerical simulations of micro-scale windfields over the steep Gauder ...
Phenomena such as large-scale shear, buoyancy, and the proximity to the ground surface significantly affect interactions among scales in atmospheric boundary layer turbulent flows. Hence, these phenomena impact parameters that enter subgrid-scale (SGS) par ...
The study of turbulent flows has always been a challenge for scientists. Turbulent flows are common in nature and have an important role in several geophysical processes related to a variety of phenomena such as river morphology, landscape modeling, atmosp ...
The 'local scaling' hypothesis, first introduced by Nieuwstadt two decades ago, describes the turbulence structure of the stable boundary layer in a very succinct way and is an integral part of numerous local closure-based numerical weather prediction mode ...
The ability of subfilter-scale (SFS) models to reproduce the statistical properties of SFS stresses and energy transfers over heterogeneous surface roughness is key to improving the accuracy of large-eddy simulations of the atmospheric boundary layer. In t ...
Large Eddy Simulations of three-dimensional turbulent compressible flows in curved duct of rectangular cross-section are presented. Strong secondary flows and turbulent structures are the typical features of this type of flow: these are responsible for mos ...
We present Large-Eddy Simulations (LES) of the turbulent compressible flow in a curved and an S-shape duct of square cross section. The aim is to predict the three-dimensional structures which develop inside the cooling channels of heat exchangers and whic ...
We present Large-Eddy Simulations (LES) of the turbulent compressible flow in curved ducts of square cross section. The aim is to investigate the influence of the curvature radius Rc on the flow and the heat transfer. We consider three different curvature ...
Large-eddy simulation LES is performed of a curved open-channel flow over topography based on the laboratory experiment by Blanckaert _“Topographic steering, flow circulation, velocity redistribution and bed topography in sharp meander bends,” Water Reso ...
