A modulated gradient model for scalar transport in large-eddy simulation of the atmospheric boundary layer

As a simple alternative to the standard eddy-diffusivity closure, a nonlinear subgrid-scale (SGS) flux model is introduced and implemented in simulations of a neutral atmospheric boundary layer and a stable atmospheric boundary layer. The new model compute ...

The Fukushima Inverse Problem

Martin Vetterli, Ivan Dokmanic, Juri Ranieri, Robin Scheibler, Marta Martinez-Camara

Knowing what amount of radioactive material was released from Fukushima in March 2011 and at what time instants is crucial to assess the risk, the pollution, and to understand the scope of the consequences. Moreover, it could be used in forward simulations ...

Wind-Turbine Wakes in a Convective Boundary Layer: A Wind-Tunnel Study

Fernando Porté Agel, Wei Zhang, Corey Dean Markfort

Thermal stability changes the properties of the turbulent atmospheric boundary layer, and in turn affects the behaviour of wind-turbine wakes. To better understand the effects of thermal stability on the wind-turbine wake structure, wind-tunnel experiments ...

A New Wall Shear Stress Model for Atmospheric Boundary Layer Simulations

Marc Parlange, Marc Calaf Bracons

A new wall shear stress model to be used as a wall boundary condition for large-eddy simulations of the atmospheric boundary layer is proposed. The new model computes the wall shear stress and the vertical derivatives of the streamwise velocity component b ...

Solute transport in nearly saturated porous media under landfill clay liners: A finite deformation approach

David Andrew Barry

For solute transport in a deformable clay liner, the importance of consolidation in the presence of sorption and consolidation-induced advection are well known. Here a one-dimensional coupled consolidation and solute transport model for a partially saturat ...

Micro systems based technologies for air-pollutant and gas detection

Danick Briand

We present a review of Microsystems-based technologies for the miniaturization of gas detection systems with a focus on air quality monitoring. On one hand, compared to sensors technologies, an approach based on microanalytical instruments can fulfill some ...

Impact of climate change on runoff pollution in urban environments

David Andrew Barry, Sylvain Coutu, Sébastien Kramer

Runoff from urban environments is generally contaminated. These contaminants mostly originate from road traffic and building envelopes. Facade envelopes generate lead, zinc and even biocides, which are used for facade protection. Road traffic produces part ...
