  1. 11. Die life prediction using High Pressure Die Casting simulations

    Magister-uppsats, Jönköping University/JTH, Material och tillverkning

    Författare :Halses Sebastian Sivertsen; [2020]
    Nyckelord :HPDC; simulations; aluminum alloys; MAGMAsoft;

    Sammanfattning : Global trends in automotive industry for weight reduction drives an interest for casting of structural aluminum parts. High pressure die casting (HPDC) is chosen for this purpose since it enables manufacturing of large series parts where complexity and repeatability is demanded. LÄS MER

  3. 12. Simulation of solidification and cooling of a casting product using COMSOL Multiphysics

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Tom Allen; [2019]
    Nyckelord :Heat transfer; casting; phase change; COMSOL Multiphysics; Technology and Engineering;

    Sammanfattning : In this project, the cooling and solidification processes for a Valmet Foundry product have been simulated in order to shorten the cooling time. The study has also been done in cooperation with RISE Swecast in Jönköping, as a part of finding ways to make casting procedures more energy efficient. LÄS MER

  4. 13. CFD Simulation of Fluid Flow During Laser Metal Wire Deposition using OpenFOAM : 3D printing

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

    Författare :Jennifer Lundkvist; [2019]
    Nyckelord :;

    Sammanfattning : The focus of this work was to simulate the fluid flow within a melt pool geometry, during an additive manufacturing process, implementing the CFD software OpenFOAM version 1806. Two separate models were created and run during this work, the first using a temperature mapping from a finite element (FE) model and the second being a free-standing model with Gaussian distributed laser beam striking down on the top surface.
