2. 1. Thermodynamic aspects and heat transfer characteristics of HiTAC furnaces with regenerators

   Author : Nabil Rafidi; Wlodzimierz Blasiak; John Witton; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Combustion; flameless; oxy-fuel; heat-recirculation; gas-recirculation; heat transfer; furnace; radiant-tube; regenerative burner; honeycomb; fixed-bed; Thermal energy engineering; Termisk energiteknik;

   Abstract : Oxygen-diluted Combustion (OdC) technology has evolved from the concept of Excess Enthalpy Combustion and is characterized by reactants of low oxygen concentration and high temperature. Recent advances in this technology have demonstrated significant energy savings, high and uniform thermal field, low pollution, and the possibility for downsizing the equipment for a range of furnace applications.

5. 3. Radiative Properties and Combustion Chemistry in Oxy-Fuel Flames – Experiments and Modelling Elements

   Author : Stefan Hjärtstam; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; Numerical modelling; Oxy-fuel; Global mechanism; Combustion;

   Abstract : The current understanding of global warming translates into an urgent need to reduce anthropogenic CO2 emissions. Carbon capture and storage is a measure to reduce CO2 emissions and oxy-fuel combustion is emerging as one possible CO2 capture process. READ MORE

   Abstract : To enable future environmentally friendly access to space by means of solid rocket propulsion a viable replacement to the hazardous ammonium perchlorate oxidizer is needed. Ammonium dinitramide (ADN) is one of few such compounds currently known. READ MORE

7. 5. Fundamental studies of non-premixed combustion in turbulent wall jets using direct numerical simulation

   Author : Zeinab Pouransari; V. Arne Johansson; Christer Fureby; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbulence; non-premixed combustion; global reaction; direct numerical simulation; wall-jet; heat release; mixing scales; heat transfer; Other engineering mechanics; Övrig teknisk mekanik;

   Abstract : The present thesis deals with the fundamental aspects of turbulent mixingand non-premixed combustion in wall-jet flows. Direct numerical simulations(DNS) of compressible turbulent flows are performed in a wall-jet configura-tion, which has a close resemblance to many industrial combustion applica-tions. READ MORE
