  1. 1. Simulation of GPHE diagonal based on full material history

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Hållfasthetslära

    Författare :Anna Gunnarsson; Jenny Hoang; [2021]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The objectives for this thesis is to further develop a finite element analysis methodology where the material history is evaluated in every step. The processing of the plate from coil to fully formed plate mounted in a heat exchanger should be taken into consideration. Material phenomena such as necking and springback are important to capture.

  3. 2. Numerical modelling for characterization of the granular flows impact on the gas flow in a packed-bed-reactor

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

    Författare :Anton Sundström; [2020]
    Nyckelord :DEM; Discrete element method;

    Sammanfattning : The goal of the project was to characterize the granular flows impact on the gas flow in a packed-bed-reactor. The study was created at Swerim as a master's thesis for Luleå University of Technology. The packed-bed-reactor geometry used in this study is a scaled down blast furnace model. LÄS MER

  4. 3. Improved methodology for postulated fuel handling accident

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Hållfasthetslära

    Författare :Max Fagerberg; [2020]
    Nyckelord :ANSYS LS-DYNA; FEM; nuclear fuel; solid mechanics; Technology and Engineering;

    Sammanfattning : This report presents a suggestion of an improved method for evaluation of a fuel handling accidents. Using a 3D FE-model and ANSYS LS-DYNA EXT the structural analysis is carried out. Importing geometry from SpaceClaim and simplifying it creates the geometry used in this analysis. LÄS MER

  5. 4. Study of a Body Subjected to a Vertical Drop into Water – Experiment and Simulations

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

    Författare :Josefin Andersson; Monika Englund; [2018]
    Nyckelord :;

    Sammanfattning : In computational fluid dynamics (CFD), the computational domain can be discretized using mesh- based methods or particle based methods. During this project; a CFD method that uses smoothed particle hydrodynamics (SPH), in which the computational domain is discretized by particles, is modelled and compared to mesh-based CFD methods, in which the domains are broken into a set of discrete volumes.

  7. 5. Bird strike analysis : AN ANALYTICAL APPROACH

    Master-uppsats, KTH/Lättkonstruktioner

    Författare :Hampus Larsson; [2016]
    Nyckelord :;

    Sammanfattning : Airplanes have a risk of encounter birds while flying, taking off or landing and to ensure a safe flight the engines have to sustain functionality after one or several bird strikes; one vital part in the engine is the first stage rotor and hence it has to withstand bird strikes. Commercial finite element codes with explicit time marching techniques are commonly used today but they can be time-consuming and therefore a faster analytical method is sought. LÄS MER
