  1. 1. 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

  3. 2. Practical investigation of mixing phenomena by physical modelling : Scaling criteria applied for bottom gas-stirred water modelling of metallurgical vessels

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Simon Garpenquist; Carl Erik Sebastian Lindfors; [2021]
    Nyckelord :Ladle furnace; Water model; Mixing time; Modified Froude number; Scaling criteria; Scaling factors; Skänkmetallurgi; Vattenmodell; Blandningstid; Froude s modifierade tal; Skalnings kriterier; Skalnings faktorer;

    Sammanfattning : Gas stirring is currently the most commonly used method of homogenizing liquid steel in commercial processes. However, due to the harsh environment during the process, physical models built out of e.g. plexiglass have been used to easier understand the complex phenomenon occurring in the process. LÄS MER

  4. 3. Investigation of the scale factor between full scale ladle furnace process and water models

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Mathias Abelin; Håkan Blomkvist; [2020]
    Nyckelord :Ladle furnace; Modified Froude number; Two-phase gas plume; Water model scaling; Skänkmetallurgi; Froudes modifierade tal; Två-fas gasplym; Skalning av vattenmodell;

    Sammanfattning : The ladle furnace process is an important process in the steel manufacturing industry. The purpose of this process is to optimize the composition of the elements in the melt as well as to homogenize the temperature in the liquid. It is common practice to model this process using smaller water models. LÄS MER

  5. 4. Near-field evolution and mixing of a negatively buoyant jet consisting of brine from a desalination plant

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :David Sánchez; [2009]
    Nyckelord :desalination plants; avsaltningsanläggning; vattenrening; salinitet; saline water; discharged water; Technology and Engineering; Earth and Environmental Sciences;

    Sammanfattning : The aim of this study was to investigate the behavior of a dense jet discharged into lighter ambient water. This situation can be found for brine water discharged from desalination plants. Desalination plants discharge heavier brine water, generated in the process of manufacturing fresh water, to the receiving water, usually the sea. LÄS MER
