  1. 1. Aerodynamics simulations of Scania trucks using OpenFOAM

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Ziyi Liu; [2024]
    Nyckelord :Heavy-duty truck; Computational fluid dynamics; Air drag; OpenFOAM;

    Sammanfattning : In the field of heavy-duty vehicles, fuel efficiency and environmental protection are factors that need to be focused on, while the aerodynamic drag generated during vehicle travelling is one of the most influential aspects. This thesis delves into the aerodynamic simulation of Scania trucks using the open-source Computational Fluid Dynamics (CFD) tool, OpenFOAM v2206. LÄS MER

  3. 2. Assessment of hydrogen supply chain for transport sector of Sweden

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :José Maria Soares Rodrigues; [2023]
    Nyckelord :Hydrogen; Hydrogen Supply Chain; Elecrolysis; 2030; Sweden; Electricity prices; MILP; Optimization; Vätgas; Vätgassupplykedja; Elektrolys; 2030; Sverige; Elpriser; MILP; Optimering;

    Sammanfattning : Fuel cell electric vehicles, powered by hydrogen are an enticing alternative to fossil-fuel vehicles in order to reduce greenhouse gas emissions and consequently accomplish the environmental targets set to tackle the environmental crisis. It is crucial to develop the appropriate infrastructure if the FCEVs are to be successfully accepted as an alternative to fossil-fuel vehicles. LÄS MER

  4. 3. Koldioxidberäkningsverktyg som kan främja hållbara beteenden : Utveckling av ett användarvänligt verktyg för vägtransportens utsläpp

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Emmy Lindberg; [2023]
    Nyckelord :carbon dioxide calculation; road transport; carbon literacy; sustainable behaviours; koldioxidberäkning; vägtransport; koldioxidlitteracitet; hållbara beteenden;

    Sammanfattning : Att minska koldioxidutsläppen är en av vår tids stora utmaningar. Transportsektorn bidrar till ökade växthusgaser, en tredjedel av Sveriges territoriella utsläpp kommer från inrikes transporter och vägtransport ansvarar för majoriteten av utsläppen. LÄS MER

  5. 4. Consumer purchasing behaviour influence on sustainable product development in the automotive industry.

    Master-uppsats, Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Författare :Ben Babu; Rohit Reddy Maddhuri; [2023]
    Nyckelord :;

    Sammanfattning : AbstractDue to increased customer knowledge of the environmental effects of conventional automobiles and their concerns, the automotive industry is undergoing a substantial change toward sustainability and environmentally friendly goods. The goal of this study is to examine the relationship between customer purchasing behaviour and new product development, with an emphasis on environmentally friendly automotive products. LÄS MER

  7. 5. Characterisation of Ionic Liquid doped Polybenzimidazole Membranes for Application in High-Temperature Proton Exchange Membrane Fuel Cells

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Adam Jacobsson Trönndal; [2023]
    Nyckelord :Fuel cells; Phosphoric acid; Polybenzimidazole; PA-PBI; Ionic liquid; IL; High temperature proton exchange membrane fuel cell; HT-PEMFC; Electrochemical impedance spectroscopy; EIS; IL-PBI; Chemical engineering; Technology and Engineering;

    Sammanfattning : In this study four membranes were tested and evaluated against each other for use in high-temperature proton exchange membrane fuel cell (HT-PEMFC) applications. A phosphoric acid (PA) doped polybenzimidazole (PBI) membrane, was used as a reference as the current state-of-the-art. LÄS MER
