  1. 1. Test rig for evaluation of protective coating against molten aluminum

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

    Författare :Sashank Ghandikota; [2023]
    Nyckelord :TES; PCM; protective coating; thermal energy storage; TES; PCM; skyddande beläggning; lagring av värmeenergi;

    Sammanfattning : Today, many methods test the lifetime of coatings, but none focus on testing protective coatingsin a non-oxidizing environment. Hence, this master thesis developed a method to test the life-time of a protective coating against molten aluminum. LÄS MER

  3. 2. Computational Analysis of Spray Deflector Designs

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Osman Gyokhan Ali; [2023]
    Nyckelord :Planing Hulls; Spray Deflector; Hull Modification; Computational fluid dynamics CFD ; resistance; trim angle; heave; CD-adapco Star CCM ; Numerical Ventilation; Phase Replacement; Modified HRIC Scheme; Volume Fraction Source Term; Reynolds averaged Navier-Stokes RANS ; Volume of Fluid VOF ; SST K-Omega Turbulence Modelling; Höghastighetshantverk; modelldesign; spraydeflektor;

    Sammanfattning : Planing hull is a common hull design concept which decreases the resistance while speed is increasing for a specific speed range. It is also suitable for hull modifications to achieve higher efficiency. Spray deflector is a promising hull modification which offers extra resistance decreasing and less vertical acceleration for planing hulls. LÄS MER

  4. 3. Deep learning for temporal super-resolution of 4D Flow MRI

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Pia Callmer; [2023]
    Nyckelord :Temporal super-resolution; 4D Flow MRI; CNN; Artificial Intelligence; MRI; 4D flow; Temporal superupplösning; 4D flöde MRI; CNN; artificiell intelligens; MRI; 4D-flöde;

    Sammanfattning : The accurate assessment of hemodynamics and its parameters play an important role when diagnosing cardiovascular diseases. In this context, 4D Flow Magnetic Resonance Imaging (4D Flow MRI) is a non-invasive measurement technique that facilitates hemodynamic parameter assessment as well as quantitative and qualitative analysis of three-directional flow over time.

  5. 4. 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.

  7. 5. CFD Results Used in the Design Process of the SEFACE Facility : KTH Master's Thesis Report

    Master-uppsats, KTH/Kärnenergiteknik

    Författare :Nathaniel Torkelson; [2022]
    Nyckelord :CFD; liquid lead corrosion; flow accelerated corrosion erosion; SEFACE; SUNRISE; ANSYS CFX; CFD; flytande blykorrosion; flödesaccelererad korrosionserosion; SEFACE; SUNRISE; ANSYS CFX;

    Sammanfattning : This project uses CFD analysis to make design choices for a facility to test flow accelerated lead corrosion erosion of steel samples. Two conceptual designs are considered and compared through mechanical and physical criteria. The first design uses steel samples on stationary plates next to rotating discs. LÄS MER
