  1. 1. Development and characterization of multi-streams heat exchangers for liquefaction cycle analysis in the contextof hydrogen mobility

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

    Författare :WULLSCHLEGER LÉA; [2023]
    Nyckelord :Liquefaction cycle; multi-streams heat exchanger; Matlab; PROOSIS; AMESIM; ArianeGroup;

    Sammanfattning : This paper presents the master thesis work done at ArianeGroup on the development and characterization of multi-streams heat exchangers for liquefaction cycle analysis in the context of hydrogen mobility. In 2015, the Paris Agreements aimed at strengthening the global response to the threat of climate change by keeping the temperature rise below 1. LÄS MER

    Sammanfattning : Massive multiple input multiple output - MIMO systems are a reality and modern communication systems rely upon this technology to cope with the increasing need for capacity and network usage. Antenna arrays are at the heart of the of the massive-MIMO system and are the enabling technology. LÄS MER

  4. 3. Investigation of Roughness Effects on Heat Transfer of Upscaled Additively Manufactured Channels in the Turbulent Region Using Infrared Thermography

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

    Författare :Kaibin Wen; [2023]
    Nyckelord :Investigation of Roughness Effects on Heat Transfer of Upscaled Additively Manufactured Channels in the Turbulent Region Using Infrared Thermography; Additiv tillverkning; värmeöverföring; infraröd termografi; ytjämnhet; finita elementmetoden;

    Sammanfattning : Additive manufacturing (AM) has largely improved design freedom compared with traditional manufacturing processes such as casting and milling. The layer-by-layer workflow makes it possible to produce objects with much more complex shapes and structures. LÄS MER

  5. 4. Design av modulärt dropoutsystem

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

    Författare :Joel Bergström; [2023]
    Nyckelord :Bicycle design; modular design; generative design; dropout; Cykeldesign; modulär design; generativ design; dropout;

    Sammanfattning : Denna rapport syftar till att ta fram ett modulärt dropout-system till en cykel, ett system som kopplar bakhjulet till ramen (det saknas en bra svensk översättning). Ett modulärt dropout-system gör det möjligt för en cykelram att använda flera olika typer av dropouts, vilket betyder att cykelramen kan anpassas efter olika användningsområden. LÄS MER

  7. 5. A Study on Building Energy Modelling and Energy Efficiency Strategies for Educational Buildings

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