  1. 1. Numerical Modelling of Gas Atomised Metal Droplets

    Master-uppsats, KTH/Materialvetenskap

    Författare :Nandakishor Thamarassery Illam Muraleedhara Sharma; [2021]
    Nyckelord :;

    Sammanfattning : The ability to predict nucleation and solidification behaviour is essential for producing high-quality  metal  powders. The  droplet  cooling  of  complex multi-component  alloy systems has not been accurately  studied  by  any models  to  date. LÄS MER

  3. 2. Solidification Modeling of Microsegregation

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Souzan Hammadi; [2018]
    Nyckelord :Solidification; casting; microsegregation; Thermo-Calc; DICTRA;

    Sammanfattning : A phase transformation from liquid to solid phase takes place when the material solidifies. Limited diffusion during this phase transition causes microsegregation, which is aphenomenon during solidification that leads to the formation of secondary phases andconcentration gradients. LÄS MER

  4. 3. Analysis of Multicomponent Data to Study Esker Structures, Turku-Finland

    Kandidat-uppsats, Uppsala universitet/Geofysik

    Författare :Julia Fridlund; [2017]
    Nyckelord :Finland; esker structures; reflection seismology; multicomponent data; S-wave; Finland; rullstensås; reflexionsseismik; flerkomponentdata; S-vågor;

    Sammanfattning : Eskers are long winding ridges that originate from gravel that has travelled in meltwater streams in glaciers. At the study site, Virttaankangas plane in southwest Finland, there are esker structures covered by sediments. One reason why it is important to study eskers is because they are used for purifying drinking water. LÄS MER

  5. 4. Numerical Modelling of Wood Pyrolysis

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Marc Mate; [2016]
    Nyckelord :biomass; gasification; renewable energy; sustainability; heat transfer; reaction engineering;

    Sammanfattning : In this project, a numerical model describing the reaction mechanism and the mass and energy transport in wood pyrolysis is studied. The applicability of the model in predicting actual biomass pyrolysis assessed by comparing the model to TGA experimental measurements. LÄS MER

  7. 5. Prediktion av proffsgolfares genomsnittscore på den amerikanska PGA-touren med hjälp av regressionsanalys

    Kandidat-uppsats, KTH/Matematisk statistik

    Författare :Robin Borgman; Axel Hellström; [2016]
    Nyckelord :;

    Sammanfattning : Detta kandidatexamensarbete undersökte huruvida proffsgolfares genomsnittscore på den amerikanska PGA-touren kunde predikteras med hjälp av regressionsanalys. Data för säsongerna 2011-2015 hämtades från PGA-Tourens hemsida. I grundmodellen användes 19 kovariat för att fånga upp så många som möjligt av golfens alla moment. LÄS MER
