  1. 1. What If We Tilt the AOD? : Developing a numerical and physical model of a downscaled AOD converter to investigate flow behaviour when applying an inclination.

    Master-uppsats, KTH/Materialvetenskap

    Författare :Serg Chanouian; [2019]
    Nyckelord :AOD; inclination angle; penetration depth; mixing time;

    Sammanfattning : In a scrap based stainless steel plant the dominant process for carbon reduction is the Argon oxygen decarburisation process (AOD). The process goes through three steps: decarburisation, reduction and desulphurisation where the main challenge is to oxidise carbon to CO without oxidising the expensive chromium. LÄS MER

  2. 2. Värmeöverföring mellan två zoner i en bubblande fluidiserad bädd

    Master-uppsats, Lunds universitet/Institutionen för Energivetenskaper

    Författare :Christian Stigsson; [2018]
    Nyckelord :Heat transfer; fluidized beds; multi-staging; Eulerian-Eulerian two-fluid; Technology and Engineering;

    Sammanfattning : In this Master's thesis, the heat transfer between two zones in a bubbling fluidized bed and the resultant temperature field were examined using a laminar Eulerian-Eulerian two-fluid model in computational fluid dynamics. The purpose was to estimate the thermal potential to multi-stage a combined heat and power boiler by integration therein of a communicating gasification reactor, which utilizes heat from the combustion, and to analyze how different construction parameters influence the homogeneity of the gas temperature field.

  3. 3. Wall Condensation Modelling in Convective Flow

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Marcus Lejon; [2013]
    Nyckelord :condensation; modelling; CFD; fluid mechanics; thermodynamics; reactions;

    Sammanfattning : Modelling condensation of water vapour is important in a number of engineering applications, such as nuclear reactor containment, rocket engine nozzles and heat exchangers. The current study investigates the possibilities of modelling condensation induced by a cold surface in a flow at high velocity and temperature. LÄS MER

  4. 4. On Multiphase Flow Models in ANSYS CFD Software

    H-uppsats, Chalmers tekniska högskola/Institutionen för tillämpad mekanik

    Författare :Elin Stenmark; [2013]
    Nyckelord :Multiphase; Computational fluid dynamics; T-junction; Phase redistribution; Euler-Euler; VOF;

    Sammanfattning : Multiphase flow is a common phenomenon in many industrial processes, amongst them the oil and gas industry. Due to the complexity of multiphase flow, development of reliable analysis tool is difficult. LÄS MER
