  1. 1. A numerical comparison of the thermoacoustics for different equivalence ratios for n-dodecane using LES

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Björn Jarfors; [2023]
    Keywords : Computational Fluid Dynamics; Bluff-body stabilised flames; Large Eddy Simulation; Thermoacoustics; Acoustics; NEUMANN Project; Jet engines; Aero engines; Airplanes; Combustion; Numerics; Technology and Engineering;

    Abstract : Klimatförändringarna påverkar vår värld och det behövs ett mer hållbart samhälle. Flygindustrin är i behov av förändring, men flygmotorer är mycket komplexa och tar tid att utveckla. Termoakustiska instabiliteter har kraften att förstöra en motor, men också att minska miljöpåverkan. READ MORE

  3. 2. 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.

  4. 3. Numerical and experimental investigation of multiple gas jet flow behaviour in the gas atomization process

    University essay from KTH/Materialvetenskap

    Author : Mahsa Darvishghanbar; [2022]
    Keywords : ;

    Abstract : 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. READ MORE

  5. 4. Characterization of surface defects caused by ultrasonic cleaning of aluminium

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Emanuel Eriksson; [2022]
    Keywords : Ultrasonic cleaning; surface cleaning; metal; aluminium; 7050; 2050; defects; surface defects; Energy Dispersive Spectroscopy; Scanning Electron Microscopy; Vertical Scanning Interferometry;

    Abstract : This master thesis studies the behaviour of two aluminium alloys in ultrasonic cleaning at two different intensities, as well as the effect of a cleaning solution, Formula 815 GD-NF on the same surface have been studied with respect to surface roughness and material composition. Methods like Light Optical Microscopy (LOM), Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS) and 3D topography using white light interferometry (VSI) was used to study the surface and material composition.

  6. 5. Development of a Design Tool in CAD for Fused Deposition Modelled Coolant Nozzles in Grinding : Design automation of coolant nozzles

    University essay from Linköpings universitet/Produktrealisering

    Author : Joachim Neguembor; [2022]
    Keywords : Design Automation; Fused Deposition Modelling; DOE; Grinding Coolant; Grinding Process; Coolant Supply in Grinding; Design of Experiment; Surrogate Model Optimization; Coolant Nozzle; Design Automering; Slipande Bearbetning; Kylvätskemunstycke;

    Abstract : This thesis covers the process of automating the design of coolant nozzles used for cylindrical grinding. Coolant nozzles are used to supply coolant, an oil and water mixture used to cool the metal workpiece and lubricate the grinding wheel. In the automotive industry, grinding is used to reduce the surface roughness of the workpiece. READ MORE
