1. 11. Network Modeling Application to Laminar Flame Speed and NOx Prediction in Industrial Gas Turbines

   Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära; Linköpings universitet/Tekniska högskolan

   Författare :Seyedeh Sepideh Marashi; [2013]
   Nyckelord :Gas turbine; combustion; NOx; emissions; laminar flame speed; burning velocity; hydrogen; network modeling; reactor network modeling;

   Sammanfattning : The arising environmental concerns make emission reduction from combustion devices one of the greatest challenges of the century. Modern dry low-NOx emission combustion systems often operate under lean premixed turbulent conditions. LÄS MER

3. 12. Determination of Laminar Burning Velocities of Nitro-methane using Heat Flux Method

   Master-uppsats, Lunds universitet/Fysiska institutionen

   Författare :Muhammad Mehboob; [2013]
   Nyckelord :Combustion Physics; Physics and Astronomy;

   Sammanfattning : In this paper the laminar burning velocities of nitromethane, ethanol and nitromethane-ethanol mixtures has been determined by using heat flux method. The laminar burning velocity of ethanol was measured at atmospheric pressure, initial temperatures range 298-358 K and equivalence ratio 0.7-1.6. LÄS MER

4. 13. The Potential of Esters as Renewable Fuels: Determination of Laminar Burning Velocities

   Master-uppsats, Lunds universitet/Fysiska institutionen

   Författare :Anas Ali Hamdi Bnayan; [2013]
   Nyckelord :Laminar burning velocity; Flame speed; Heat flux method; Ester fuels; renewable energy; Physics and Astronomy;

   Sammanfattning : The Potential of Esters as Renewable Fuels: Determination of Laminar Burning Velocities Biodiesel fuel is widely used as a clean fuel in car engines. Ester fuels are a one kind of a biodiesel fuel which includes many chemical compounds. Due to their chemical and physical properties these esters are difficult to investigate in a laboratory.

5. 14. Laminar Burning Velocity of Ethanol, Acetaldehyde and Ethanol-Acetaldehyde Flames

   Master-uppsats, Lunds universitet/Fysiska institutionen

   Författare :Mengistu Abebe; [2013]
   Nyckelord :Laminar burning velocity; Temperature; Equivalence ratio; Ethanol and Acetaldehyde; Physics and Astronomy;

   Sammanfattning : The objective of this study is to get new experimental data regarding to the burning velocities of ethanol, acetaldehyde and their mixture which has been performed by the heat flux method. It is known that the heat flux method for determination of laminar burning velocities is an efficient technique since the burning velocity can be determined directly, without applying extrapolations.

7. 15. Laminar burning velocities of methanol mixed with formaldehyde and statistical examination of the heat flux burners

   Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

   Författare :Emelie Flood; [2012]
   Nyckelord :Methanol; formaldehyde; statistical analysis; burner; heat flux method; Matlab; biofuel; combustion; fuel; density; temperature; laminar burning velocity; acetone; thermocouple; equivalence ratio; Earth and Environmental Sciences; Chemistry; Physics and Astronomy;

   Sammanfattning : Combustion of methanol is being used widely and the chemistry in the process is therefore important to know. When being mixed with formaldehyde and combusted previous measurements with the heat flux method have shown results not consistent with the theoretical models present today. These experiments are in this paper being repeated. LÄS MER
