  1. 11. Numerical study of a jet impacting a heated object

    Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Författare :Moutaz Hammoud; [2023]
    Nyckelord :Numerical model; COMSOL Multiphysics; Heat transfer; Impinging jets.;

    Sammanfattning : Heat transfer brought about by impinging jets is common in several industrialapplications such as the cooling of heated objects. The purpose of this investigationis to create a numerical model of an impacting jet, then to use it in parametricresearch and in the cooling of an electronic device. LÄS MER

  3. 12. Modelling Gas Flow Behaviour in Gas Atomizer

    Master-uppsats, KTH/Materialvetenskap

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

    Sammanfattning : 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.

  4. 13. Bose-Einstein Condensate Jets from Different Traps

    Magister-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Författare :Emmanuel-Roosevelt D Costa; [2022]
    Nyckelord :Bose-Einstein Condensate; Jets; Bose Fireworks; Gross-Pitaevskii equation; Physics and Astronomy;

    Sammanfattning : This thesis presents a numerical study of the emission of jets by a trapped Bose-Einstein Condensate (BEC). The Gross-Pitaevskii equation is used for the simulation of this phenomenon. When the scattering length of a trapped BEC is periodically modulated it emits jets of matter. LÄS MER

  5. 14. Numerical and experimental investigation of multiple gas jet flow behaviour in the gas atomization process

    Master-uppsats, KTH/Materialvetenskap

    Författare :Mahsa Darvishghanbar; [2022]
    Nyckelord :;

    Sammanfattning : In several industrial applications, the interaction of supersonic gas jets is encountered such as gas atomization, jet engines and the basic oxygen furnace process. In the gas atomization process, high pressure gases are converted to high velocity gas jets through convergent-divergent nozzles. LÄS MER

  7. 15. Constraining Physics Beyond the Standard Model with Emerging Jets using the ATLAS Experiment

    Kandidat-uppsats, KTH/Fysik

    Författare :Simon Thor; [2022]
    Nyckelord :ATLAS; CERN; particle physics; simulation; Python; C ; standard model; emerging jets; long-lived particles;

    Sammanfattning : Dark matter, the unknown matter that constitutes 85% of all matter in the universe, is one of the greatest mysteries in fundamental physics. One theory that might explain dark matter predicts that there are long-lived particles known as dark pions. LÄS MER
