  1. 6. Pressure loss characterization for cooling and secondary air system components in gas turbines

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Frida Isaksson; [2017]
    Keywords : Gas turbines; cooling and secondary air system; pressure losses; discharge coefficient; minor loss; one-dimensional modelling;

    Abstract : There is a constant struggle to increase the efficiency in gas turbines, where one method is to have a higher inlet temperature to the turbine. Often, this results in temperatures higher than the critical temperature of the materials, which makes cooling of the components an important part of the turbine. READ MORE

  3. 7. Investigation and Validation of Cooling Loss Models for Axial Gas Turbines

    University essay from KTH/Energiteknik

    Author : Jacob Händestam; Eric Jacobson; [2017]
    Keywords : axial gas turbines; one-dimensional; aerodynamics; cooling; losses; loss models; validation; axiella gas turbiner; endimensionell; aerodynamik; kylning; förluster; förlust modellering; validering;

    Abstract : Detta arbete behandlar undersökningen och valideringen av kylförlustmodellen i det nyligen framtagna programmet för endimensionell turbindesign, Mean Line Tool (MLT), skapat av Siemens Industrial Turbomachinery AB (SIT). Huvudsyftet är att undersöka med vilken noggrannhet MLT kan prediktera de extra aerodynamiska förluster som uppstår vid injektion av kylluft i en turbinpassage. READ MORE

  4. 8. Experimental Investigation of Fuel Mixing Concepts for 3rd Generation DLE Burners : Evaluation Through Water Rig and Atmospheric Combustion Rig Measurements

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Jonathan Lönning; [2016]
    Keywords : ;

    Abstract : New Siemens burner concepts thought to produce a more homogeneous air/fuel mix-ture and a better distribution of the fuel over the burner cross section have been evaluated. A homogeneous air/fuel mixture is known to produce the lowest levels of emitted oxides of nitrogen (NOx) which is a main objective for Siemens Industrial Turbomachinery AB (SIT). READ MORE

  5. 9. Quality Assurance of Pressure Equipment Materials and Steelwork

    University essay from Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska högskolan

    Author : Filip Horkeby; Melanie Larsson; [2016]
    Keywords : PED; CE; logistik; kvalitetskontroll;

    Abstract : Kvalitetskraven i samhället blir allt högre och det blir allt tuffare för producenterna att hålla de kvalitetskrav som krävs av kund, men också att uppnå de kvalitetsdirektiv som finns i EU idag. Det finns idag en mängd olika definitioner på vad kvalitet är och hur kvaliteten ska uppnås. READ MORE

  6. 10. Method Development for Heat Transfer Predictions in Channel Flows : An efficient CFD approach for ribbed stationary channels

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Martin Leskovec; [2016]
    Keywords : CFD; roughened channels; heat transfer coefficient; HTC; Nu number; CAE process;

    Abstract : Gas turbines are today used in numerous industrial and aeronautical applications. To increase the specific power output and efficiency, a high turbine inlet gas temperature is desired. The high temperature leads to the need of cooling critical components in the hot gas path. READ MORE
