Field study of the dynamics and modelling of subgrid-scale turbulence in a stable atmospheric surface layer over a glacier

Wolf Hendrik Huwald, Marc Parlange, Charles Vivant Ignacio Meneveau, Chad Higgins

A field experiment – the Snow Horizontal Array Turbulence Study (SnoHATS) – has been performed over an extensive glacier in Switzerland in order to study small-scale turbulence in the stable atmospheric surface layer, and to investigate the role, dynamics ...

On the Diurnal Soil Water Content Dynamics during Evaporation using Dielectric Methods

Marc Parlange, Ivan Lunati, Scott W. Tyler

The water content dynamics in the upper soil surface during evaporation is a key element in land–atmosphere exchanges. Previous experimental studies have suggested that the soil water content increases at the depth of 5 to 15 cm below the soil surface duri ...

Large-Eddy Simulation of the Convective Atmospheric Boundary Layer over Heterogeneous Land Surfaces

Marc Parlange, Chad Higgins, Daniel Nadeau

The parameterization of the atmospheric boundary layer is crucial for accurate numerical weather predictions. Over heterogeneous terrain, several open challenges remain regarding the growth of internal boundary layers, the determination of mixing layer hei ...

Large-Eddy Simulation of the Convective Atmospheric Boundary Layer over Heterogeneous Land Surfaces

Marc Parlange, Chad Higgins, Eric Richard Pardyjak, Daniel Nadeau

The parameterization of the atmospheric boundary layer is essential for accurate numerical weather predictions. The near-surface values of air temperature or wind speed for instance are highly dependent on the complex land – atmosphere interactions over he ...

Two-phase hydrodynamic and sediment transport modeling of wave-generated sheet flow

David Andrew Barry, Roham Bakhtyar

This numerical investigation was carried out to advance mechanistic understanding of sediment transport under sheet flow conditions. An Euler-Euler coupled two-phase flow model was developed to simulate fluid-sediment oscillatory sheet flow. Since the conc ...

MHD Stability Analysis of IDB Plasma in LHD

Wilfred Anthony Cooper

The characteristics of magnetohydrodynamics (MHD) stability of plasmas with the internal diffusion barrier (IDB) are intensively studied in the Large Helical Device (LHD) experiment. These plasma are produced by the rapid fueling into the core region with ...

Dissipative processes in interchange driven scrape-off layer turbulence

Jonathan Graves, Richard Pitts, Jan Horacek

First principles expressions are given for the parameters governing collisional diffusion and parallel losses of mass, momentum and energy in tokamak scrape-off layer (SOL) plasmas. These dissipative, or damping, coefficients are based on neoclassical perp ...

The non-circular shape of FloWatch®-PAB prevents the need for pulmonary artery reconstruction after banding

Alfio Quarteroni, Paolo Zunino, Ludwig Von Segesser

To evaluate the differences between non-circular shape of FloWatch®-PAB and conventional pulmonary artery (PA) banding. Methods: Geometrical analysis. Conventional banding and FloWatch®-PAB perimeters were plotted against cross-sections. Computational flui ...
