Oil Discharge and Transport in a Natural River

Tomas Ekström1,Klara Linden2
1Carl Bro AB Energy, 2Lunds University

A discharge of hydraulic oil is assumed from an hydroelectric power station. The oil is let out through the outlet from the turbines and is spread into the river. The flow of water, or more correctly, the solution of water and oil, is calculated by Navier-Stoke equation for incompressible fluids. The concentration of oil is calculated by a mass-balance equation. It is assumed that oil is absorbed ...

Modeling NOx Adsorption on NaZSM-5 Film with FEMLAB

Indra Perdana, Derek Creaser

Chalmers University of Technology

A model describing transport of NOx into a NaZSM-5 film and kinetics for reactions forming nitrates species was developed using FEMLAB. The film consists of a thin layer of intergrown NaZSM-5 crystals supported on a cordierite monolith support. Model predictions of outlet gas concentration were fitted to experimental data using a nonlinear regression function in MATLAB. Parameter fitting was ...

Chemical Engineering Education in the Digital Age

H. Scott Fogler
University of Michigan
Michigan, USA

Today's students have been interacting with computers from an early age. This presentation answers the questions: How do we teach today's students? How do today's students learn? How can technology enhance learning? What are types of student learning styles? --------------------------------- Keynote speaker's biography: Professor H. Scott Fogler, a distinguished educator who excels in ...

Inertia Mixer in CD Microfluidics

G. Kylberg

Gyros AB is developing biomedical laboratories in CD-discs, Gyrolab®. In a lot of applications mixers are needed and for some special applications liquid volumes of a few microlitres are to be handled. The mixing of a few microlitres liquids was studied numerically with FEMLAB and experimentally with colored and uncolored water. Thanks to this combination, the main mixing process was ...

Virtual Prototyping

Björn Engquist
Royal Institute of Technology, Stockholm and University of Texas
Austin, USA

Virtual prototyping is used for understanding, verifying, planning, controliing, and optimizing a technical application. It the industrial component computational science and engineering and can be called "the third pillar of modern science". The future of virtual prototyping will be multiscale and multiphysics models and simulations. --------------------------------- Keynote speaker's ...

The benefit of using FEMLAB 3.1 as a tool in teaching biomechanics and biomedical physics at Uppsala University

Jesper Gantelius
Uppsala University
Uppsala, Sweden

The alveolus is the smallest functional unit of the lung, and is the only region where oxygen from the air enters the bloodstream, as well as where carbon dioxide is vented out. There are approximately six hundred million alveoli in the lungs of every human, and the branched lungs seem to mimic a fractal surface to provide a total area of exchange of more than a hundred square meters. The ...
