Modelling Waste Water Flow in Hollow Fibre Filters

I. Borsi[1] and A. Fasano[1]
[1]Dipartimento di Matematica U. Dini, Università di Firenze, Firenze, Italy

In this paper we present a model to describe the process of waste water filtration based on hollow-fibre membrane filters. In particular, we deal with membranes whose pores diameter is in the range 0.01-0.1 µm. The main problem in these filtering systems is the membrane fouling. ... Read More

Transport Phenomena and Shrinkage Modeling During Convective Drying of Vegetables

S. Curcio[1] and M. Aversa[1]
[1]Department of Engineering Modeling, University of Calabria, Arcavacata di Rende, CS, Italy

The aim of the present work is the formulation of a theoretical model describing the transport phenomena involved in food drying process. The attention has been focused on the simultaneous transfer of momentum, heat and mass occurring in a convective drier where hot dry air flows, in ... Read More

Local Conduction Heat Transfer in U-pipe Borehole Heat Exchangers

J. Acuna[1] and B. Palm[1]

[1]Department of Energy Technology, KTH, Stockholm, Sweden

The most common way to exchange heat with the bedrock in Ground Source Heat Pump (GSHP) applications is circulating a fluid through a U-formed closed loop in vertical boreholes drilled several tenths of meters into the ground. This study presents and compares the results of eight cross ... Read More

Detection of Magnetic Particles by Magnetoresistive Sensors

A. Weddemann[1], A. Auge[1], F. Wittbracht[1], C. Albon[1], and A. Hütten[1]
[1]Department of Physics, Thin Films and Physics of Nanostructures, Bielefeld University, Bielefeld, Germany

In this work, we demonstrate the implementation of the micromagnetic equations for the description of ferromagnetic thin films in COMSOL Multiphysics®. We apply our model to magnetoresistive sensors consisting of several soft ferromagnetic layers and their response to magnetic particles. ... Read More

Model of Heat and Mass Transfer with Moving Boundary During Roasting of Meat in Convection-Oven

A.H. Feyissa[1], J. Adler-Nissen[1], and K.V. Gernaey[2]
[1]Food Production Engineering, National Food Institute, Technical University of Denmark, Kgs. Lyngby, Denmark
[2]Department of Chemical and Biochemical Engineering, Technical University of Denmark, Kgs. Lyngby, Denmark

A 2D mathematical model of coupled heat and mass transfer describing oven roasting of meat was formulated from first principles. The current formulation of model equations incorporates the effect of shrinkage phenomena and water holding capacity. The model equations are based on ... Read More

[1]Department of Biophysical and Electronic Engineering, University of Genova, Genova, Italy
[2]SELEX Communications S.p.A., Genova, Italy

Gas sensor arrays based on metal oxides operating at high temperature are commonly used in many application fields. They can operate on different principles and each sensor may show very different responses to the individual gases in the environment. Data coming from the array can be ... Read More

Chip Drop After Silver Sintering Process

M.H. Poech[1], M. Weiß[1], and K. Gruber[1]

[1]Fraunhofer Institute for Silicon Technology, Itzehoe, Germany

Since a couple of years, sintering becomes more and more important for power electronics. To press a semiconductor under high temperature in silver paste on a substrate promises benefits for durability. Tests with semiconductors of different thickness expose some problems. After the cool ... Read More

B. Hari[1] and C. Theodoropoulos[1]
[1]The University of Manchester, School of Chemical Engineering and Analytical Science, Manchester, UK

Microreactors are important alternative to conventional reactors in chemistry, chemical, pharmaceutical and semiconductor industries due to their operation characteristics such as increased mass and heat transfer, uniform flow, safety, high throughput through array configurations, ... Read More

Safe Storage Parameters During CO2 Injection Using Coupled Reservoir ...

Safe Storage Parameters During CO₂ Injection Using Coupled Reservoir-Geomechanical Analysis

T.I. Bjørnarå[1], E. Aker[1], and E. Skurtveit[1]
[1]NGI, Oslo, Norway

Safe short term storage of CO2 depends mainly on structural and solubility trapping. On longer term, mineral trapping is also contributing to the trapping of CO2. To be able to investigate the importance of these different storage mechanisms, a finite element model for simulation of CO2 ... Read More
