  1. 21. Factors influencing the generation of carbon monoxide in fires partially suppressed through water mist application

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Haydn Lewis; [2020]
    Nyckelord :Fire safety engineering; water mist; fire suppression; carbon monoxide; water; combustion; Technology and Engineering;

    Sammanfattning : Fires in the built environment typically consist of diffusion flames with inefficient mixing of fuel and oxygen, resulting in a degree of incomplete combustion and the generation of carbon monoxide. Fire suppression systems, used to control the growth and spread of fire, influence the combustion reaction process. LÄS MER

  3. 22. Design Investigation into Liquid Oxygen Vaporisation Systems : Atomisation and Heat Loads

    Master-uppsats, KTH/Energiteknik

    Författare :Borbala Bernus; [2020]
    Nyckelord :LOx; gasification; two-phase CFD simulation; rapid oxidation; rocket; cryogenic; hybrid; atomisation; LOx; förgasning; 2-fas CFD-simulering; snabb oxidation; raket; kryogen; hybrid; atomisering;

    Sammanfattning : Computational Fluid Dynamics (CFD) simulations are presented within this study for super-cooled liquid oxygen atomisation and gasification in a subcritical chamber operating at 1MPa. Relatively low cost simulation techniques have been used and their accuracy evaluated. LÄS MER

  4. 23. Volatile fatty acid production and application as external carbon source for denitrification

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Cora Michelle Döhler; [2020]
    Nyckelord :VFAs; co-fermentation; primary sludge; food waste; denitrification; external carbon source; MBBR;

    Sammanfattning : By rethinking wastewater treatment plants (WWTPs) as resource recovery facilities, it is possible to de- velop the next generation of WWTPs. Moreover, it allows to accomplish environmental goals, such as reducing the CO2 footprint, and comply with increasing effluent standards regarding the concentration of nitrogen in a more sustainable way.

  5. 24. Preliminary design of a small-scale liquid-propellant rocket engine testing platform

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Erik Andersson; [2019]
    Nyckelord :;

    Sammanfattning : Propulsion system testing before mission operation is a fundamental requirement in any project. For both industrial and commercial entities within the space industry, complete system integration into a static test platform for functional and performance testing is an integral step in the system development process.

  7. 25. Investigating the influence of water in lysozyme structure and dynamics using FT-IR and XRD

    Kandidat-uppsats, Stockholms universitet/Fysikum

    Författare :Rafat Yousif; [2019]
    Nyckelord :water; lysozyme; crystalline water; supercooled water; hydrogen bonds; FT-IR; XRD; hydration water; protein folding; protein dynamic transition;

    Sammanfattning : Water is “the matrix of life” for its fascinating properties. The well-known simple water molecule consists of one oxygen atom and two hydrogen atoms, covering most of planet earth’ssurface. It is the most studied element in science; however, its properties are still not fully understood. LÄS MER
