On The Purification Of Waste Waters Using Multi-Bore Filters: Simulation Of A Long-Term Filtration Stage

I. Borsi
Dipartimento di Matematica U. Dini, Universita' di Firenze, Italy

We present the progress of the simulation activity we are carrying out within the PURIFAST LIFE+ project. We first present the model we formulated to describe the macroscopic effects of the filtration process taking place in a multi-bore filter, focusing on the fouling phenomenon. In ... Read More

Evaluation of COMSOL as a Tool for Pinpointing Moisture Entering Locations From Inside Surface Moisture

J. van Schijndel
Eindhoven University of Technology, Eindhoven, Netherlands

The location and nature of the moisture leakages are sometimes difficult to detect. Moreover, the relation between observed inside surface moisture patterns and where the moisture enters the construction is often not clear. The objective of this paper is to investigate inverse modeling ... Read More

Simulating A Fan For Industrial Ventilation

G. Argentini
Riello Burners, Italy

This work talks on simulation of a ventilating structure for an industrial burner. The mathematical model is based on the frozen-rotor technique, and the numerical simulation is used for resolution of fluid dynamics equations for the air flow into the rotating wheel and into the static ...

Design Improvement Of A Bench-Scale Nanofiltration Device By CFD Study

B. Balannec[1,2], T. Renouard[1,2], and F.Cortès-Juan[3]
[1]Université de Rennes 1-ENSCR-CNRS, France
[2]Université européenne de Bretagne, France
[3]Universidad Politécnica de Valencia, Spain

Feasibility studies in the field of membrane processes are generally first carried out with bench-scale membrane filtration cells. These small laboratory cells also allow evaluating the influence of operational parameters and the membrane performances. Smart design of the cell geometry ... Read More

Numerical Model For Rocking Of Mono-Pile In A Porous Seabed

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

Offshore wind and wave energy industries have developed considerably in the last two decades. Most offshore energy structures used in the existing projects are mono-piles in shallow water due to simplicity of installations, design and control. Numerous research for the design and ... Read More

Transport Phenomena of Bubbles in a High Viscous Fluid

F. Pigeonneau
CNRS/Saint-Gobain, France

Dr. Franck Pigeonneau is currently working in the joint laboratory between the Centre National de la Recherche Scientifique (CNRS) and the company Saint-Gobain. He received his Ph. D. in 1998 from the University Pierre et Marie Curie (Paris, France). His main research activities are ... Read More

COMSOL Assistance For The Determination Of Pressure Drops In Complex Microfluidic Channels

J. Berthier, R. Renaudot, P. Dalle, G. Blanco-Gomez, F. Rivera, P. Caillat, and V. Agache
CEA-LETI, Grenoble, France

With the current trend towards always more complexity associated to more functionalities in biotechnological systems, it is required to know with accuracy the pressure drop in the circuitry of microfluidic systems. In general, a full three-dimensional calculation is not tractable due to ... Read More

Blistering of Industrial Floors on Concrete Substrate: The Role of Air Overpressure

P. Devillers[1], S.V. Aher[2], G. Fau[3], B. Tranain[3], and C. Buisson[1]
[1]Centre des Matériaux de Grande Diffusion, Ecole des Mines d’Alès, France
[2]Department of Civil Engineering, Indian Institute of Technology Kanpur, Kanpur, Uttar Pradesh, India
[3]Centre Scientifique et Technique du Bâtiment, Champs sur Marne, France

A three dimensional COMSOL Multiphysics, transient analysis, diffusion model has been adopted to model the transfers of water in the industrial concrete floors. To take into account the different initial saturation levels at the different levels of the slab, the model is divided into ... Read More

Model and Simulation of a Tunable Birefringent Fiber Using Capillaries Filled with Liquid Ethanol

C. Zeringue, and G.T. Moore
Air Force Research Laboratory, Kirtland Air Force Base, NM, USA

Conventional polarization maintaining fiber is constructed using a pair of borosilicate rods on either side of the fiber core. Current manufacturing processes prohibit the construction of fibers with the required accuracy needed for applications requiring precision birefringence. Through ... Read More

Navier-Stokes Solutions for Flow and Transport in Realistic Porous Media

N. Abdussamie
American Bureau of Shipping, Tripoli, Libya

This paper illustrates how to set up and solve a two-dimensional flow problem having dimensions of 640 x 320 micro-meter using the Navier-Stokes equations with the help of COMSOL Multiphysics solver. The principle of our pore-scale modeling approach is composed of two steps. The first ... Read More
