Vortex Dynamics in Transitional and Turbulent Boundary Layers
Vortex Dynamics Transitional Turbulent Boundary Layers
2016/5/18
The dynamics of transitional and turbulent boundary layers is explored via a hybrid vortex filament/finite volume simulation scheme in which vortical structures are identified without the constraints ...
A NEW MEAN VELOCITY SCALING FOR TURBULENT BOUNDARY LAYERS
TURBULENT BOUNDARY LAYERS MEAN VELOCITY SCALING
2014/12/30
A new scaling, originally developed for the mean velocity
profile of turbulent pipe flow, was extended to the case of zero
pressure gradient turbulent boundary layers. At low Reynolds
numbers, the ...

A simple eddy viscosity formulation for turbulent boundary layers near smooth walls
Momentum equation Model equation A near-wall eddy viscosity formulation
2011/8/29
The aim of this study is to improve the prediction of near-wall mean streamwise velocity pro le U+ by using a simple method. The U+ pro le is obtained by solving the momentum equation which is written...
A regional real-time forecast of marine boundary layers during VOCALS-REx

2011/1/20
This paper presents an evaluation and validation of the Naval Research Laboratory's COAMPS® real-time forecasts during the VOCALS-REx over the area off the west coast of Chile/Peru in the Southeas...
Diffusive boundary layers do not limit the photosynthesis of the aquatic macrophyte Vallisneria americanaat moderate flows and saturating light levels
Diffusive boundary layers do not limit the photosynthesis the aquatic macrophyte Vallisneria americana moderate flows saturating light levels
2014/4/17
Hydrodynamic models of mass transport assume that diffusive processes next to the surface limit transport and that there are no biological and chemical processes that control the supply and demand of ...
Universal dependences between turbulent and mean flow parameters instably and neutrally stratified Planetary Boundary Layers
Universal dependences mean flow parameters stratified Planetary Boundary Layers
2009/11/9
We consider the resistance law for the planetary boundary layer (PBL) from the point of view of the similarity theory. In other words, we select the set of the PBL governing parameters and search for ...

Extending the Similarity Theory for Atmospheric Boundary Layers: Contribution from Background Stratification
Atmospheric boundary layer similarity theory turbulence stratification effects
2009/6/10
The structure of the atmospheric boundary layer has traditionally been described using only surface fluxes and the Coriolis parameter. We review here the proposal of Kitaigorodskii (1988) and Kitaigor...
Turbulent dispersion in cloud-topped boundary layers
Turbulent dispersion cloud-topped boundary layers
2009/3/13
Compared to dry boundary layers, dispersion in cloud-topped boundary layers has received less attention. In this LES based numerical study we investigate the dispersion of a passive tracer in the form...
