  2. 1. Infrared Laser-Induced Grating Techniques for Diagnostics in Reactive Flows

    Author : Dina Hot; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Laser diagnostics; infrared; laser-induced grating spectroscopy; degenerate four-wave mixing; flames; temperature; concentration; Fysicumarkivet A:2020:Hot;

    Abstract : AbstractThe work presented in this thesis is mainly focused on the development andapplication of infrared laser-induced grating techniques in order to measure the gasphase temperature and species concentrations in reactive flows. The two techniquesused for this purpose are laser-induced grating spectroscopy (LIGS) and degeneratefour-wave mixing (DFWM). READ MORE

  4. 2. Aspects of creep-fatigue in gas turbine hot parts

    Author : Magnus Hasselqvist; Gunnar Härkegård; Linköpings universitet; []
    Keywords : creep; fatigue; TMF; gas turbine; modelling; life assessment; ageing; micro-structure; solute drag; back stress; Haynes 230; IN792;

    Abstract : The goal is reliable creep-fatigue lifing methodology for industrial gas turbines.A literature study on high temperature materials used in gas turbines reveals that:• Most testing/modelling work has focused on characterisation and modelling of material response in isothermal standard tests, i.e. creep, tensile and LCF tests.

  6. 4. Developing Humidified Gas Turbine Cycles

    Author : Michael Bartlett; KTH; []
    Keywords : advanced gas turbine cycles; evaporative; humidified; power; heat and power;

    Abstract : As a result of their unique heat recovery properties,Humidified Gas Turbine (HGT) cycles have the potential todeliver resource-effective energy to society. The EvaporativeGas Turbine (EvGT) Consortium in Sweden has been studying thesetypes of cycles for nearly a decade, but now stands at acrossroads, with commercial demonstration remaining. READ MORE

  7. 5. Externally fired gas turbine cycle based on biomass gasification gas as fuel

    Author : Fabiola Baina Veizaga; Torsten Fransson; Lasse Rosendhal; KTH; []
    Keywords : Externally fired micro gas turbine; heat transfer; combustion of biomass derived gas; micro combined heat and power; Energiteknik; Energy Technology;

    Abstract : Energy services are essential for the development of societies, reduce poverty, and improve the living standards of inhabitants. The conventional routes to provide energy services employ fossil fuels. However, this involves environmental and availability concerns. READ MORE
