  1. 1. Green Room : A climate controlling grow-box for growing mushrooms and greens.

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Bill Skullman; Gabriella Herlin; [2023]
    Nyckelord :Mechatronics; Aeroponic farming; Mushroom farming; Photosynthesizing plants - Greens; Ultrasonic atomizer; Mekatronik; Aeroponisk odling; Svampodling; Fotosyntetiserande växter; Ultraljudsluftfuktare;

    Sammanfattning : This report covers a project on a partially automated aeroponic and fungi growing system. The purpose is to evaluate if an enclosed space system can be automated to produce healthy crops of greens and fungi, and investigate how well the system can switch between these two growth modes.

  3. 2. Early Stage Design of a Prefilmer at Siemens Energy : Numerical and Experimental Methodology

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Jean-Pierre Hamzo; [2023]
    Nyckelord :CFD; gas-turbine; computational fluid dynamics; atomizer; prefilmer; RANS; LES; multi-phase; experimental; numerical; atomization; spray characteristics; drop breakup; liquid fuels; liquid films;

    Sammanfattning : Design of atomizers for gas-turbine purposes are an important ordeal. The per-formance of the atomizer directly impacts the efficiency of the gas-turbine, andconsequently, the energy extracted from the turbine. Furthermore, the design ofthe atomizer can have an impact on reducing toxic emissions. LÄS MER

  4. 3. 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.

  5. 4. Improving gas flow in gas atomization

    Master-uppsats, KTH/Materialvetenskap

    Författare :Zhiwei Qiu; [2021]
    Nyckelord :;

    Sammanfattning : 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. LÄS MER
