1. 11. Numerical modeling of air-fiber flows

   Författare :Jelena Andric; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aggregation; particle-level simulation; rheology; fiber; dry-forming; fiber suspension;

   Sammanfattning : The dynamics of fiber suspensions are of great importance in applications such as the dry-forming process of pulp mats for use in hygiene products. In this forming process, fibers are transported in flowing air. The fibers interact with the fluid, and may interact with each other and interlock in flocs. LÄS MER

3. 12. Slopes in soft clay - management of strength mobilisation

   Författare :Victoria Svahn; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; remedial measure; dry crust; climate change; Slope stability; pore water pressure; in situ stress; soft clay; shear strength mobilisation;

   Sammanfattning : Many natural and man-made slopes close to buildings or infrastructure do not demonstrate sufficient levels of safety with respect to their stability. Nonetheless, it is a requirement from society that the environment we live in is safe. LÄS MER

4. 13. Co-disposal of waste rock and lignite fly ash to mitigate the environmental impact of coal mining

   Författare :Asif Qureshi; Björn Öhlander; Christian Maurice; Thomas Pabst; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Acid mine drainage AMD ; coal mine waste rocks; coal fly ash; co-disposal; mixing blending; dry-cover; prevention neutralisation; Tillämpad geokemi; Applied Geochemistry;

   Sammanfattning : Waste rocks (WRs) from coal mining and fly ash (FA) from coal combustion were studied to determine the potential of the WRs to generate AMD, FAs to neutralise it and estimate their impacts on environment. The ultimate goal was to develop a methodology based on co-disposal to mitigate the environmental problems associated to both wastes. LÄS MER

5. 14. High ash non-coking coal preparation by tribo-electrostatic dry process

   Författare :Ranjan Dwari; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

   Sammanfattning : Coal is the single largest fossil fuel used world-wide and accounts for more than 60% of the total commercial energy consumed. Between 60 to 80% of this coal is used for electric power generation and most of which through a system of pulverised coal combustion. LÄS MER

7. 15. Combustion Characteristics of a Swirl Dry Low Emission Burner Concept for Gas Turbine Application : Experiments and Simulations

   Författare :Atanu Kundu; Kraftverksteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gas Trubine Combustion; Partially Premixed flame; Flame stabilization; Swirl Flow; Emission; Experiments; Combustor; CFD; PLIF; PIV; Chemiluminescence;

   Sammanfattning : In the current global energy scenario, gas turbine can provide delicate balance between the booming worlds energy requirement and a pollutant free sustainable society. Cleaner combustion of fuel (particular natural gas), efficient, reliable, low maintenance and cost effective operation of gas turbine attracted scientific community to push the limit further (high efficiency and zero emission gas turbine).
