2. 1. Laser-Based Investigations of Combustion Phenomena in Gas Turbine Related Burners

   Author : Arman Subash; Förbränningsfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Combustion; Gas turbine; Chemiluminescence; laser-based techniques; LIF; PIV; DLE; TARS; CH4; H2; OH; CH20; Equivalence ratio; flame stabilization; LBO; Flashback; RPL; Fysicumarkivet A:2018:Subash;

   Abstract : Experiments were performed on various combustion devices to investigate the flames employing different optical measurement techniques under atmospheric pressure conditions. Non-intrusive laser-based techniques provided in-situ information concerning different parameters of the combustion process, with a high degree of temporal and spatial resolution. READ MORE

4. 2. Application of Laser-based Diagnostics to a Prototype Gas Turbine Burner at Selected Pressures

   Author : Ronald Whiddon; Förbränningsfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; OH; Laser Diagnostics; Elevated Pressure; Syngas; DLE; NOx; Combustion; Gas Turbine; PIV; PLIF; Pilot; SGT-750; Fysicumarkivet A:2014:Whiddon;

   Abstract : The matured laser-diagnostic techniques of planar laser-induced fluorescence (PLIF) and particle image velocimetry (PIV) were applied to a prototype gas turbine burner operating on various fuels. The work was performed to provide verification of computational fluid dynamic (CFD) models of the combustion of atypical fuels in a gas turbine combustor. READ MORE

5. 3. Development of LPP-Burner for Industrial Gas Turbine Application

   Author : Jonas Holmborn; Strömningsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal engineering; Dry Low Emission DLE ; Lean Partially Premix LPP ; Combustion; Gas Turbine; Burner; applied thermodynamics; Termisk teknik; termodynamik;

   Abstract : This thesis reports the work done in the development of a modified Lean Premix Prevaporised (LPP) burner for the use in Alstom Power Sweden’s industrial gas turbines. Incentive for the development of the modified burner have been the need to increase the flame stability over the operating range for the burner, especially for the liquid fuel but also the gaseous fuel operation.

6. 4. Fabrication and Characterization of ZnO Nanorods Based Intrinsic White Light Emitting Diodes (LEDs)

   Author : Nargis Bano; Omer Nour; Magnus Willander; David Rogers; Linköpings universitet; []
   Keywords : Zinc Oxide nanorods; White light emitting diode; Photoluminescence; Cathodoluminescence; Electroluminescence; Deep level transient spectroscopy DLTS ;

   Abstract : ZnO material based hetero-junctions are a potential candidate for the design andrealization of intrinsic white light emitting devices (WLEDs) due to several advantages overthe nitride based material system. During the last few years the lack of a reliable andreproducible p-type doping in ZnO material with sufficiently high conductivity and carrierconcentration has initiated an alternative approach to grow n-ZnO nanorods (NRs) on other ptypeinorganic and organic substrates.

7. 5. 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
