  1. 16. Detailed Soot Modelling in Laminar and Turbulent Reacting Flows

    Författare :Michael Balthasar; Förbränningsmotorer; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; soot; turbulent; flames; engines; turbines; carbon black; ionization; laminar; Physics; Fysik; Fysicumarkivet A:2000:Balthasar;

    Sammanfattning : In the present work a detailed kinetic soot model is applied to study the formation and oxidation of soot particles in laminar premixed and turbulent non-premixed flames. The soot model used in this study is based on a detailed description of the chemical and physical processes involved in the formation of soot. LÄS MER

  3. 17. Life cycle navigation through future energy carriers and propulsion options for the energy transition in shipping

    Författare :Fayas Malik Kanchiralla; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; environmental impact; life cycle costing; battery electric; fuel cells; electro-fuel; technical feasibility; economic impact; hydrogen; life cycle assessment; carbon capture; marine fuel; engines; ammonia; carbon abatement cost; shipping; methanol;

    Sammanfattning : The shipping industry's heavy reliance on fossil fuels has a detrimental effect on the global climate, human health, and the natural environment. The shipping sector now relies on the use of cheap and energy-dense heavy fuel oil and is perceived as ‘difficult-to-decarbonize’. LÄS MER

  5. 19. Thermodynamics of microscopic environments: From anomalous diffusion to heat engines

    Författare :Aykut Argun; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; microscopic thermodynamics; anomalous diffusion; deep learning; heat engines;

    Sammanfattning : Till skillnad från deras makroskopiska motsvarigheter utvecklas inte mikroskopiska system deterministiskt på grund av inverkan från termiskt brus. Sådana system är föremål för fluktuationer som endast kan studeras inom ramen för stokastisk termodynamik. LÄS MER

  7. 20. Emission and Deposit Formation in Direct Injection Stratified Charge SI Engines

    Författare :Håkan Sandquist; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; cycle-resolved measurements; deposit formation; direct injection; stratified charge; hydrocarbon emissions; SI engines; fuels;

    Sammanfattning : A promising approach to increase the efficiency of the spark ignition (SI) engine is to inject the fuel directly into the cylinder to form a stratified charge. There is a potential to reduce the fuel consumption at low speeds and loads by 20 - 25% compared with conventional SI engines with stoichiometric homogeneous charge. LÄS MER
