  1. 1. Exploratory study of additively manufactured heat exchangers for aerospace applications

    Master-uppsats,

    Författare :Siddharth Nadukkandy; [2023]
    Nyckelord :;

    Sammanfattning : Thermal management is a crucial part in the aviation industry. It is also essential that the components involved in aviation be light weight. One of the vital components of thermal management is heat exchangers. It has been observed that the optimization of the heat exchanger is approaching its saturation with traditional manufacturing.

  3. 2. CFD Analyses for Wind Load AssessmentCFD Analyses for Wind Load Assessment : Wind-induced vibrations in the Bomarsunds Bridge hangers

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Fatiha El Azrak; [2023]
    Nyckelord :;

    Sammanfattning : The trend in recent years of building longer and slender bridge components has introduced new challenges to ensure their stability and strength. This master thesis focuses on the effects of wind-induced vibrations in the context of long, slender arch bridge components, particularly the recently constructed Bomarsunds Bridge in Åland, Finland.

  4. 3. Structural Dynamics at Higher Frequencies using the Finite Element Method : Assessment of Solver Algorithms and Component Mode Synthesis for Dynamic Response Analysis of Large Structures

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Khashaiar Noushin; [2022]
    Nyckelord :;

    Sammanfattning : Scania is making a transition from traditional combustion engines to electric vehicles and therefore developing methodology for high frequency analysis of large structures. The computational time size of results files are impractically high, making any analysis infeasible. LÄS MER

  5. 4. Rotor Dynamic Modeling of Hydropower Rotors by 3D-Finite Element Analysis

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Simon Pääjärvi; [2022]
    Nyckelord :Rotordynamics; Applied Mechanics; Dynamics; Rotor; Finite Element Analysis; Hydropower; Solid Mechanics; Energy Production;

    Sammanfattning : By using the rotor dynamic capabilities of Simcenter Nastran Rotordynamics, an eigenvalue analysis of 3D-finite element models of the Jeffcott rotor and the overhung rotor were conducted and compared to the results with beam-based, lumped parameter models. The first two critical speeds of the Jeffcott rotor were estimated with variations of 3. LÄS MER

  7. 5. An aeroelastic prediction model for slender wings in supersonic flow

    Master-uppsats, KTH/Flygdynamik

    Författare :Zakarias Priebe; Alexander Hasp Frank; [2021]
    Nyckelord :;

    Sammanfattning : Aeroelasticity is a multidisciplinary subject encompassing several fields of study. Aeroelastic behaviour is defined by the relation between inertial-, elastic- and aerodynamic forces that appear in dynamic systems in steady- or unsteady conditions. LÄS MER
