2. 1. Experimental investigation of premixed ammonia combustion at high Karlovitz number conditions

   Author : Qingshuang Fan; Förbränningsfysik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbulent premixed combustion; Ammonia flames; Laser diagnostics; Flame structure; High Karlovitz number; Turbulent burning velocity; Fysicumarkivet A:2021:Fan;

   Abstract : This thesis aims to acquire deep knowledge on turbulent premixed combustion at high Karlovitz (Ka) number conditions with the help of laser-based diagnostic measurements.Considering that ammonia (NH3), as a carbon-free energy carrier, is a promising candidate for replacing conventional fossil fuels in the future, all the investigations in this work were carried out on ammonia/air premixed flames.

4. 2. Experimental studies of turbulent flames at gas turbine relevant burners and operating conditions

   Author : Xin Liu; Förbränningsfysik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbulent Combustion; Gas Turbine; Laser diagnostic; Fuel flexibility; Plasma-assisted combustion; Ammonia flame; High pressure;

   Abstract : With the increasing demand of using alternative and renewable fuels, it becomes of vital importance to consider the fuel flexibility when designing a new burner for gas turbines. Hydrogen-enriched fuel and ammonia are two of these potential fuels, and they can significantly change the operability range of the gas turbines. READ MORE

5. 3. Formation and Transformation of Atmospheric Brown Carbon (BrC)

   Author : Kalyan Mitra; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; brown carbon BrC ; primary organic aerosol POA ; secondary organic aerosol SOA ; BrC bleaching; BrC browning; Toluene photo-oxidation; NOx; Ammonia; NH3; acidity effects; light absorption;

   Abstract : Atmospheric brown carbon (BrC) aerosol absorbs light in the UV-Vis spectrum and has poorly constrained but potentially large climate forcing impacts. Most current climate models lack detailed chemistry and interlinked properties of atmospheric BrC, that induce large uncertainties in radiative forcing predictions. READ MORE

6. 4. Numerical studies of flame stabilization relevant to gas turbine engines using methane and e-fuels

   Author : Yazhou Shen; Christophe Duwig; Benoit Fiorina; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Mechanics; Teknisk mekanik;

   Abstract : The current society undergoes a global energy transformation from fossil fuels to renewable energy. The alternative energy sources to fossil fuels are key factors to accelerate the transition towards a sustainable energy system. Among those, electrofuels (e-fuels) is a promising group that remarkably benefits overall carbon neutrality. READ MORE

7. 5. Laminar burning velocity of hydrogen and flame structure of related fuels for detailed kinetic model validation

   Author : Vladimir Alekseev; Förbränningsfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; hydrogen combustion; laminar burning velocity; ICLAS; temperature dependence; heat flux method; Fysicumarkivet A:2015:Alekseev;

   Abstract : The laminar burning velocity and the flame structure are common targets for combustion studies aimed at detailed kinetic model development. In the present work, fuels relevant to hydrogen combustion were considered. READ MORE
