2. 1. Particulate Flows in Aftertreatment Systems

   Author : Henrik Ström; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modeling; Computational fluid dynamics; Exhaust gas aftertreatment; Particulate matter; Multiphase flow; Particulate flow;

   Abstract : Emissions from internal combustion engines contain many components that have a detrimental effect on the environment and on human health, such as nitrogen oxides (NOx) and particulate matter (PM). In addition, the final product of any combustion of fossil fuel - carbon dioxide (CO2) - contributes to global warming. READ MORE

4. 2. Compaction, Flow and Dispersion in a Chromatographic Column

   Author : Karin Östergren; Livsmedelsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; compression; chromatography; particulate bed; hydrodynamic dispersion; theoretical model; flow field; Livsmedelsteknik;

   Abstract : An experimental and theoretical study of compaction, flow and hydrodynamic dispersion in a chromatographic column containing non-rigid particles is presented. Experiments were performed using chromatographic columns packed with either a dextran-based chromatographic gel or glass beads. READ MORE

5. 3. Eulerian-Eulerian Modeling of Turbulent Gas-Particle Flow

   Author : Aldo Benavides; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kinetic theory of granular flow; Eulerian approach; two-phase flow; CFD;

   Abstract : Gas-particle flow is encountered in a vast number of industrial operations and natural phenomena. Computational fluid dynamics plays an important role in practical engineering and fundamental research activities. READ MORE

6. 4. Particulate and gaseous emissions from residential biomass combustion

   Author : Christoffer Boman; Anders Nordin; Ingwald Obernberger; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; aerosols; air pollution; emissions; fuel pellets; residential biomass combustion; inorganic characterization; incomplete combustion; particulate matter; polycyclic aromatic hydrocarbons; trace elements; Kemi; Chemistry; Kemi;

   Abstract : Biomass is considered to be a sustainable energy source with significant potentials for replacing electricity and fossil fuels, not at least in the residential sector. However, present wood combustion is a major source of ambient concentrations of hydrocarbons (e.g. READ MORE

7. 5. On the Agglomeration of Particles in Exhaust Gases

   Author : Ghulam Majal; Mihai Mihaescu; Mats Åbom; Mikael Karlsson; Lisa Prahl Wittberg; Henrik Ström; KTH; []
