Numerical simulation of colloidal dispersion filtration: description of critical flux and comparison with experimental results [PDF]
, 2006 During filtration via membrane processes, colloids accumulate at the porous surface leading to fouling phenomena. In this study, a rigorous simulation of momentum and mass transfer using CFD modelling has been developed to describe such an accumulation ...

Ozone Flux Measurement and Modelling on Leaf/Shoot and Canopy Scale
Italian Journal of Agronomy, 2008 The quantitative study of the ozone effects on agricultural and forest vegetation requires the knowledge of the pollutant dose absorbed by plants via leaf stomata, i.e. the stomatal flux.

LES in the Surface Layer: Surface Fluxes, Scaling, and SGS Modeling
Journal of the Atmospheric Sciences, 1998 Abstract The surface fluxes in the fine-mesh numerical codes used in small-scale meteorology are typically diagnosed from resolvable-scale variables through surface-exchange coefficients. This is appropriate if the aspect ratio (length/height) of the grid volume adjacent to the surface is very large, as in mesoscale models.

The location of the thermodynamic atmosphere–ice interface in fully coupled models – a case study using JULES and CICE [PDF]
Geoscientific Model Development, 2016 In fully coupled climate models, it is now normal to include a sea ice component with multiple layers, each having their own temperature. When coupling this component to an atmosphere model, it is more common for surface variables to be calculated in the

Modeling surface fluxes over a sparse vegetation
Archives of Biological Sciences, 2012 In this paper some of aspects in modeling over sparse vegetation using the Land-Air Parameterization Scheme (LAPS), including an approach in calculating the turbulent transfer coefficient using ?K-theory? inside a sparse vegetation canopy, were considered. For this purpose, the scheme was run for different sparse agricultural cultivars, i.e.
