  1. 1. Optimisation of the gas atomisation process used in aluminium powder production : To improve morphology by minimising satellite formations

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Henrik Hedlin; Johan Nymo; [2023]
    Nyckelord :;

    Sammanfattning : There exists a lack of information and an exact understanding of the gas atomisation process resulting in the use of trial and error methods in the industry. The lack of information is the result of the difficulties in observing the actual process as it occurs, something that the use of computational fluid dynamics may be able to substitute. LÄS MER

  3. 2. Numerical Modelling of Gas Atomised Metal Droplets

    Master-uppsats, KTH/Materialvetenskap

    Författare :Nandakishor Thamarassery Illam Muraleedhara Sharma; [2021]
    Nyckelord :;

    Sammanfattning : The ability to predict nucleation and solidification behaviour is essential for producing high-quality  metal  powders. The  droplet  cooling  of  complex multi-component  alloy systems has not been accurately  studied  by  any models  to  date. LÄS MER

  4. 3. Numerical and experimental investigations of gas jet used in atomisation of metal powders

    Master-uppsats, KTH/Materialvetenskap

    Författare :Arun Kamalasekaran; [2020]
    Nyckelord :;

    Sammanfattning : The environmental impact caused by the traditional production techniques has led to increased research in the field of alternative production techniques such as additive manufacturing. However, the environmental sustainability of the manufacturing techniques that produce and supply powders to the additive manufacturing process can be improved significantly. LÄS MER

  5. 4. Design Investigation into Liquid Oxygen Vaporisation Systems : Atomisation and Heat Loads
