  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. Optimization and Additive Manufacturing for HPGP Rocket Engines

    University essay from KTH/Kraft- och värmeteknologi

    Author : Jessie Stachowicz; [2022]
    Keywords : Additive Manufacturing; Rocket Propulsion; Nozzle Design; Computational Fluid Dynamics; CFD; Nasa CEA; DED; PBF; High Performance Gas Propulsion; ADNbasedPropellant; CD Nozzle; Additiv tillverkning; raketframdrivningssytem; munstycksdesign; beräkningsflödesanalys; CFD; Nasa CEA; DED; PBF; högpresterande gasframdrivning; ADNbasedPropellant; Konvergerande-divergerande munstycken;

    Abstract : This thesis aims to investigate whether additive manufacturing is applicable in manufacturing the 1N thruster option that Bradford Ecaps offers. Therefore, the nozzle design is of particular interest as AM provides accessibilities to manufacturing complex structures. READ MORE

  4. 3. Turbo For Fuel Cell Electric Vehicle

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Adam Hansson; Mohammed Abu Al-Soud; [2022]
    Keywords : Turbo; Fuel Cell; Centrifugal Compressor; Radial Turbine; Axial Turbine; Technology and Engineering;

    Abstract : Turbo systems have long been implemented into vehicles to increase the specific power. Increasing the pressure for conventional vehicles decreases the mass of the engine and increases the efficiency. Conventional vehicles do however produce carbon dioxide emissions which have become an increasing issue that needs a solution. READ MORE

  5. 4. Geometrical Improvement of Fuel Nozzle Locations in the SGT-750 Gas Turbine : An investigation into fuel-air mixing in main channels 1 & 2

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Aryan Delir; [2022]
    Keywords : gas turbine engines; turbofan; combustion; SGT-750; flashback; hydrogen; natural gas; premixing; fuel-air mixing; computational fluid dynamics; CFD; turbulence modelling; NOx emission; lean premixed mixture;

    Abstract : This study was conducted on SGT-750, which utilizes can type fourth generation DLE burner, developed at Siemens Energy AB, in Finspång, Sweden. The aim of this study is to obtain a flat fuel profile at the outlet of main channel 1 and main channel 2, demonstrating a proper mixing of fuel and air in the main channels leading to reducing local high-temperature points, and thus, reducing thermal NOx emissions.

  6. 5. 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
