  1. 1. Modelling Gas Flow Behaviour in Gas Atomizer

    University essay from KTH/Materialvetenskap

    Author : Aravind Senan Vasanthasenan Reji; [2022]
    Keywords : Gas atomization; Nozzle; Velocity; Static pressure; Discrete phase model; Gasatomisering; Munstycke; Hastighet; Statiskt tryck; Diskret fasmodell;

    Abstract : Gas atomization is regarded as a reliable method for creating high-quality metal powders from molten metal. The liquid metal is fed into the chamber as a free-falling stream through a nozzle, where it is impinged by high-velocity gas jets, causing degeneration and production of metal droplets, which solidify to create metal powders.

  3. 2. Investigation on how additive manufacturing with post-processing can be used to realize micronozzles

    University essay from Uppsala universitet/Ångström Space Technology Centre (ÅSTC)

    Author : Alan Bugurcu; [2022]
    Keywords : additive manufacturing; micronozzle; micro rocket nozzle; laser-powered powder bed fusion; electropolishing; supersonic micronozzle; supersonic micro rocket nozzle; titanium alloy; titanium-64; Ti-Al6-V4;

    Abstract : This is predominantly a qualitative study on the manufacturing of micronozzles with an additive manufacturing (AM) technique, namely the laser-powered powder bed fusion (PBF-LB).  Manufacturing of micronozzles with standard microelectromechanical system technology often results in 2.

  4. 3. Improving gas flow in gas atomization

    University essay from KTH/Materialvetenskap

    Author : Zhiwei Qiu; [2021]
    Keywords : ;

    Abstract : Gas atomization is a cost-effective processing method to produce fine, spheroidized metal powders. During the process, high velocity jets of gas are sprayed at a molten metal stream to break it into small droplets, which will solidify and form the powder particles. READ MORE

  5. 4. Schlieren imaging of microrocket jets

    University essay from Rymdtekniskt centrum

    Author : Ville Lekholm; [2009]
    Keywords : Schlieren imaging; schlieren photography; microthruster; microexhaust; microrocket;

    Abstract : In this report, microrockets from the company NanoSpace were studied using schlieren imaging techniques. The rocket chips are manufactured using MEMS technology, which requires compromises regarding the shape of the nozzle. The rocket chips are 22x22x0.85 mm, manufactured from laminated silicon.
