  1. 1. MODELLING OF HEAT TRANSFER OF RAILWAY SWITCH HEATING

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Siddharth Suresh Sumathi; [2023]
    Keywords : Conjugate Heat transfer analysis; transient analysis; CFD; insulation; measurement data uncertainties.; Konjugat Värmeöverföringsanalys; transientanalys; CFD; isolering; mätdata osäkerheter.;

    Abstract : Switches and crossings are vital components of the railway network. Obstacles to the smooth functioning of these components could result in delays and network traffic. Given the geographical location of Sweden, snow is one of the major obstacles for the switches. READ MORE

  3. 2. Methodology for analysis of vibration isolating systems

    University essay from Linköpings universitet/Mekanik och hållfasthetslära

    Author : Jonas Olsson; [2023]
    Keywords : Vibration;

    Abstract : Vibration causes problems in many kinds of machinery including fighter aircraft. It can, for example, cause structural fatigue, malfunction in equipment and injuries to humans. The sources of vibration are engines, flow disturbance and separation of external loads, to mention some. READ MORE

  4. 3. Micro-architectured materials for thermal management : Porous graphite/graphene boiling enhancement structures

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Melody Ghaderidosst; [2022]
    Keywords : Microarchitecture; TPMS; Gyroid; thermo-mechanical; computational homogenization; graphite; graphene;

    Abstract : The convergence of the digital and physical world encourages advances in high-speed telecommunication and fifth generation technology. Two-phase heat transfer systems are common engineering solutions. However, due to the large frequency spectra in 5G, the systematic heat generation increases requiring more efficient thermal management. READ MORE

  5. 4. Numerical study of the effect of thermal ice loads on concrete dams

    University essay from KTH/Betongbyggnad

    Author : Imal Zuwak; Wasseem Kordoghly; [2020]
    Keywords : Arch dam; Buttress dam; Concrete; Finite element analysis; Ice load; Valvdamm; Lamelldamm; Betong; Finit elementanalys; Islast;

    Abstract : It is essential to understand the mechanics of ice load and how it affects concrete dams located in a cold climate, such as Sweden, where the temperature becomes sufficiently cold to freeze the surface of the reservoir. The purpose of this thesis is to study ice load distribution along concrete dams, and its response during the application of an ice load. READ MORE

  6. 5. Material parameter study for aheavy-vehicle exhaust manifoldusing the finite element method : to increase component lifetime and decrease its environmental impact

    University essay from Linköpings universitet/Konstruktionsmaterial

    Author : David Ek; [2019]
    Keywords : Thermomechanical fatigue; TMF; material parameter study; finite element method; FEM;

    Abstract : The thesis originates from a need to meet stricter environmental regulations for Scania, to reduce fuel consumption and emission from heavy-vehicles. Scania aims to fulfil these requirements by increasing combustion pressure and temperature. These conditions are tougher for the engine components and they shorten their lifetime. READ MORE
