  4. 2. Application of Numerical Aerothermal Models on Jet Engine Combustors

    Author : Stefan Olovsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The use of numerical simulations with combustion for predicting the flow field in a gas turbine combustor or afterburner may reduce the required time in the development process. To investigate the performance of numerical simulation codes some different combustor geometries was studied. READ MORE

  5. 3. Numerical Modeling of Flows Related to Gas Turbine Combustors

    Author : Robert-Zoltán Szász; Strömningsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; plasma; fluid dynamics; plasmas; Gaser; fluiddynamik; Gases; vortex breakdown; swirl; CFD; gas turbine;

    Abstract : The thesis focuses on the numerical simulation of the flow field in gas turbine burners. Due to tougher and tougher requirements on low levels of emission of pollutants there is a need for new combustion technologies. In gas turbines one method to attain low pollutant levels is the use of lean premixed combustion. READ MORE

  6. 4. Development of catalysts for natural gas-fired gas turbine combustors

    Author : Sara Eriksson; Magali Boutonnet; Pio Forzatti; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AZEP; catalytic combustion; CPO; methane oxidation; palladium; rhodium; support effect; Chemical engineering; Kemiteknik;

    Abstract : Due to continuously stricter regulations regarding emissions from power generation processes, further development of existing gas turbine combustors is essential. A promising alternative to conventional flame combustion in gas turbines is catalytic combustion, which can result in ultralow emission levels of NOx, CO and unburned hydrocarbons. READ MORE
