2. 11. Spray combustion with multiple-injection in modern engine conditions

   Author : Ahmad Hadadpour; Strömningsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spray combustion; Multiple-injection; Internal combustion engine; LES; FGM; ESF;

   Abstract : Combustion of fuel in diesel engines emits substances harmful to the environment such as soot. These emissions can be reduced by either in-cylinder treatments or after-treatments. One of the common in-cylinder treatments is multiple-injection, which divides a single fuel injection to multiple smaller injections. READ MORE

4. 12. On-Engine Turbocharger Performance Considering Heat Transfer

   Author : Habib Aghaali; Hans-Erik Ångström; Jose R. Serrrano; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbocharger; Internal combustion engine; heat transfer; turbocharged engine; on-engine turbocharger; turbocharger performance; توربو شارژر، موتور احتراق داخلی، انتقال حرارت، توربوچارجر; turbo; turboladdare; förbränningsmotor; värmeöverföring; turboladdad motor;

   Abstract : Heat transfer plays an important role in affecting an on-engine turbocharger performance. However, it is normally not taken into account for turbocharged engine simulations. READ MORE

5. 13. Laser Spectroscopic Techniques for Combustion Diagnostics Directed Towards Industrial Applications

   Author : Hans Seyfried; Förbränningsfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Teknik; Technological sciences; Fysik; Physics; Combustion; Gas turbine; HCCI; Engine; High-Speed; Thermographic phosphors; PLIF; LIF; Laser Diagnostics; Laser-Induced Fluorescence; Laser technology; Laserteknik; Motors and propulsion systems; Motorer; framdrivningssystem;

   Abstract : In the work presented in the thesis, different laser spectroscopic techniques were utilized for measurement of species concentrations, as well as for surface thermometry. Experiments were conducted in various combustion environments, ranging from laboratory burners to truck-sized internal combustion (IC) engines, gas turbine combustors and a full-size aircraft turbofan engine.

7. 15. Development and application of laser diagnostics - from laboratory devices towards practical combustion engines

   Author : Zhenkan Wang; Förbränningsfysik; []
   Keywords : Combustion diagnostics; Laser induced fluorescence LIF ; Ultra-high-speed; Burst-mode laser; Ballistic imaging; Particle imaging velocimetry; Laser Doppler anemometry; Turbulent premixed combustion; Plasma; Internal combustion engine; Partially premixed combustion PPC ; Auto-ignition; OH radical; CH2O formaldehyde ; Fysicumarkivet A:2018:Wang;

   Abstract : For many decades, research work on combustion has been focused on improving combustion efficiency and reducing harmful emissions. Laser diagnostics is one of the best ways to investigate the combustion process and emission formation as it is non-intrusive and it has high spatiotemporal resolution. READ MORE
