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

    University essay from KTH/Energiteknik

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

    Abstract : 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. READ MORE

  3. 2. A THERMAL NETWORK MODEL FOR AN EVAPORATIVE COOLING SYSTEM COMBINED WITH A SOLAR CHIMNEY

    University essay from KTH/Energiteknik

    Author : LIVIO JACONELLI; KIM JACONELLI PALM; [2016]
    Keywords : ;

    Abstract : Syftet med denna studie är att, genom termiskt nätverksmodellering för kombinerad värme och massöverföring, undersöka möjligheten att integrera en solskorsten med en evaporationskyl. Avsikten är att potentiellt öka luftflödet runt kylen samt dess kylförmåga. READ MORE

  4. 3. Thermogravimetric analysis and modeling of pyrolysis of macroscopic wood particles

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : YOSRA PERSNIA; [2016]
    Keywords : Biomass; gasification; renewable energy; thermogravimetric analysis; mathematical modeling;

    Abstract : The knowledge of kinetics of pyrolysis is important. It is also challenging to find parameters for kinetic which can be applied at different sizes of biomass. Many researchers have been investigating the pyrolysis behavior of wood powders due to heat and mass transfer limitations. READ MORE

  5. 4. Absorption of CO2 : - by Ammonia

    University essay from Institutionen för teknik och design

    Author : Filip Sjöstrand; Reza Yazdi; [2009]
    Keywords : Carbon capture; mass transfer; carbon dioxide; absorption; ammonia; packed column; Avskiljning av koldioxid; massöverföring; koldioxid; absorption; ammoniak; packad kolonn;

    Abstract : In this diploma work, the absorption of CO2 in different liquid solutions was studied by gas absorption in a randomly packed column. To characterize the absorption a few experiments with SO2 absorption were made.The report has resulted due to the large amounts of carbon dioxide released into the atmosphere, mainly from fossil-fired power plants.
