2. 11. CFD Modeling of Turbulent Flows in Industrial Applications with Emphasis on Premixed Combustion in Gas Turbines

   Author : Ulf Engdar; Kraftverksteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; framdrivningssystem; Motorer; turbulence and premixed combustion modeling ; CFD modeling ; level-set flamelet library approach ; emissions ; gas turbine ; compressor washing ; spray modeling ; Technological sciences; Teknik; Energy research; Energiforskning; Thermal engineering; applied thermodynamics; Termisk teknik; Motors and propulsion systems; termodynamik;

   Abstract : Increasing restrictions on hazardous emissions combined with demands for good profitability from the operators in the energy market have contributed strongly to the development of innovations in which the emphasis is on low emissions and high efficiency. For gas turbine-based power plants, emission of NOx in particular is governed by stringent legislation. READ MORE

4. 12. Aerothermodynamics and exergy analysis in turbocharger radial turbine

   Author : Shyang Maw Lim; Mihai Mihaescu; Anders Dahlkild; Ricardo Martinez-Botas; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pulsatile exhaust flow; turbine; turbocharger; Detached Eddy Simulation; heat transfer; exergy; Engineering Mechanics; Teknisk mekanik;

   Abstract : Coupling of turbomachine to reciprocating automotive engine in turbocharging leads to complex fluid flow and thermal characteristics in the turbine. Some undesirable characteristics include heat transfer, flow pulsation and secondary flow due to the complex geometry of the upstream exhaust manifold. 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.

   Abstract : Industrial digitalization and its promises propel manufacturing firms to pursue digital reality. When changing ways of working, organizational actors often introduce digital artifacts to create a preferred situation where digital technology creates and shapes physical reality. READ MORE

7. 15. Diagnosis and Supervision of Industrial Gas Turbines

   Author : Emil Larsson; Jan Åslund; Erik Frisk; Lars Eriksson; Mattias Henriksson; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Monitoring of industrial gas turbines is of vital importance, since it gives valuable information for the customer about maintenance, performance, and process health. The performance of an industrial gas turbine degrades gradually due to factors such as environment air pollution, fuel content, and ageing to mention some of the degradation factors. READ MORE
