  4. 3. Turbulent premixed flames in a model gas turbine combustor: fuel sensitivity and flame dynamics

    Författare :Francesco Pignatelli; Strömningsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fuel flexibility; Premixed turbulent combustion; DNS; Optical diagnostic;

    Sammanfattning : The demand for energy security and reduction of greenhouse gas emissions has led to a surge of interest in the development of high-efficiency and low-emission gas turbine engines that can run on alternative low carbon content fuels, such as hydrogen-enriched fuel and syngas. However, the combustion characteristics of these fuels can significantly alter the flame characteristics and operability range of existing combustors. LÄS MER

  5. 4. A Study of the Adhesion Strength of Plasma Sprayed Coatings

    Författare :Fouzi Bahbou; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Splat.; Surface roughness; Mechanical anchoring; Grit blasting; Adhesion strength; Protal® process; Fractal analysis; Thermal spraying; Coating; Surface pre-treatment;

    Sammanfattning : Surface preparation prior to thermal spraying is a key factor in ensuring a good adhesion of the coating onto the part to be coated. Surface pre-treatment conditions and methods have mainly been developed experimentally and have changed little over the years. LÄS MER

  7. 5. Integration environmental aspects into product development : proactive measures

    Författare :Sofia Ritzén; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ecodesign; integrated product development; environmental aspects; Industrial engineering and economy; Industriell teknik och ekonomi;

    Sammanfattning : Environmental concern has greatly increased in magnitude within the companies of Swedish industry. Product development has become a strategic area: the environmental adaptation of products is fundamental for a decrease in environmental impact from human activities, and product development is an area of the greatest importance to the competitiveness of companies.
