  1. 1. Numerical Modelling of Gas Atomised Metal Droplets

    University essay from KTH/Materialvetenskap

    Author : Nandakishor Thamarassery Illam Muraleedhara Sharma; [2021]
    Keywords : ;

    Abstract : 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. READ MORE

  3. 2. Solidification Modeling of Microsegregation

    University essay from KTH/Materialvetenskap

    Author : Souzan Hammadi; [2018]
    Keywords : Solidification; casting; microsegregation; Thermo-Calc; DICTRA;

    Abstract : 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.

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

    University essay from Uppsala universitet/Geofysik

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

    Abstract : 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. READ MORE

  5. 4. Numerical Modelling of Wood Pyrolysis

    University essay from KTH/Skolan för kemivetenskap (CHE)

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

    Abstract : 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. READ MORE

  6. 5. A comparison of the multicomponent model and the mixture averaged approximation

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Author : Martin Torstensson; [2014]
    Keywords : Combustion physics; computational physics; multicomponent model; mixture averaged approximation; Physics and Astronomy;

    Abstract : In this work the major models for calculating diffusion in simulations of a laminar premixed hydrogen flame, the mixture averaged approximation and the multicomponent model, are explained and compared. This is done in order to see if the accuracy gained in implementing the multicomponent model is enough to warrant the increased workload the transition will cause. READ MORE
