  1. 16. 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).

  3. 17. The skin barrier : structure and physical function

    Författare :Lars Petter Oskar Norlén; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The objective of the project "The skin barrier - structure and physical function" was to characterise in detail the human skin barrier structurally and functionally. The thesis work includes in-vivo studies, in-vitro studies and studies on pure model systems. LÄS MER

  4. 18. Numerical Modeling of Soot and NOx Formation in Non-Stationary Diesel Flames with Complex Chemistry

    Författare :Feng Tao; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; soot and NOx formation; non-stationary Diesel sprays; complex chemistry; Diesel spray auto-ignition; reaction zone structure; Diesel flame liftoff; turbulence-chemistry interaction;

    Sammanfattning : A complex chemistry model of reduced size (65 species and 268 reactions) derived on the basis of n-heptane auto-ignition kinetics, small hydrocarbon oxidation chemistry, polyaromatic hydrocarbon (PAH) and NOx formation kinetics together with a phenomenological soot model has been implemented in the KIVA code for multidimensional Diesel spray combustion simulations. An EDC (Eddy Dissipation Concept) based partially stirred reactor model is used to handle the turbulence-chemistry interaction. LÄS MER

  5. 19. Laminar burning velocity of hydrogen and flame structure of related fuels for detailed kinetic model validation

    Författare :Vladimir Alekseev; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; hydrogen combustion; laminar burning velocity; ICLAS; temperature dependence; heat flux method; Fysicumarkivet A:2015:Alekseev;

    Sammanfattning : The laminar burning velocity and the flame structure are common targets for combustion studies aimed at detailed kinetic model development. In the present work, fuels relevant to hydrogen combustion were considered. LÄS MER

  7. 20. Flame nanoengineering of antibiofilm surfaces for medical implants

    Författare :Felix J. Geissel; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Infection of bone implants is a major problem in the Healthcare sector today. Over the last years it has started to become more problematic due to biofilm formation and increasing antimicrobial resistance (AMR). A biofilm provides mechanical shielding to bacteria by ingulfing them leading to a less effective treatment with antibiotics. LÄS MER
