2. 1. Numerical and experimental investigation of a gasturbine model combustor with axial swirler

   Author : Michael Bertsch; Strömningsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flashback; swirl; gasturbine; combustor; methane; hydrogen; LES; PLIF;

   Abstract : This thesis presents the simulations of and experiments with the so-called CECOST burner. The CECOST burner is a gas turbine model combustor equipped with an axial swirler and placed in a laboratory for the lean premixed turbulent combustion of a range of fuels at atmospheric pressure.

4. 2. On Premixed Gas Fuelled Stirling Engine Combustors with Combustion Gas Recirculation

   Author : Magnus Pålsson; Förbränningsmotorer; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration and acoustic engineering; Maskinteknik; vakuumteknik; vibrationer; akustik; Motors and propulsion systems; Motorer; framdrivningssystem; hydraulik; Mechanical engineering; hydraulics; vacuum technology; termodynamik; Termisk teknik; applied thermodynamics; Thermal engineering; heat pipe; ejector; solar energy; CGR; recirculation; EGR; catalytic combustion; premix combustion; Stirling engine; combustor;

   Abstract : The main objective in the research described in this thesis was to design and test the use of lean premixed combustion using combustion gas recirculation for gas fuelled Stirling engine combustors. A system using a flame-arrester type of flame-holder to stabilize the flame and an ejector system for the recirculation of combustion gas was designed and tested in the laboratory. READ MORE

5. 3. Numerical Simulations of Cooling Concepts Related to Gas Turbine Combustors
