It consists of a composite drop suspended in a continuous phase. This composite drop has a smaller inner drop suspended within the larger ... Read More

Integrated Model For Ocean Waves Propagating Over Marine Structures On A Porous Seabed

D-S. Jeng, X. Luo, and J. Zhang
Division of Civil Engineering, University of Dundee, Dundee, Scotland, UK

In this paper, an integrated model for ocean waves propagating over a submerged coastal structure, based on COMSOL Multiphysics, is presented. In the model, Navier-Stoke Equation is solved for the wave propagation and Biot’s poro-elastic model is solved for the porous seabed. The new ... Read More

The Soil as Bioreactor: Reaction-diffusion Processes and Biofilms

M. Richter[1], S. Moenickes[2], O. Richter[2], T. Schröder[1]
[1]BASF SE, Agricultural Center, Limburgerhof, Germany
[2]Institute of Geoecology, TU Braunschweig, Braunschweig, Germany

In a soil pore, water flows through the biofilm, where the density of the latter was assumed to represent a flow resistance. This mechanism was implemented as a local change of fluid viscosity proportional to local biofilm density. It was assumed that diffusive substrate transport is ... Read More
