1. 21. Component State Prediction Based on Field Data : Master Thesis in Energy System Engineering

   University essay from

   Author : Linnea Johansson; [2017]
   Keywords : Gas Turbine; Prediction Model; Failure model; Field data; Environmental attributes; Weibull Distribution; Bayesian Statistics;

   Abstract : This master thesis is part of a big project at Siemens Industrial Turbomachinery (SIT) in Finspång aimed to use the operation experience available at SIT to predict the state of the gas turbines in general and some mechanical components in particular. The objective of the thesis is to continue the development of a prediction model based on experience data for estimations of a components lifetime. READ MORE

3. 22. 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

4. 23. ThermoacousticInstabilities in a Gas Turbine Combustor

   University essay from KTH/MWL Marcus Wallenberg Laboratoriet

   Author : Karl Bengtsson; [2017]
   Keywords : ;

   Abstract : Stationary gas turbines are widely used today for power generation and mechanical drive applications. The introduction of new regulations on emissions in the last decades have led to extensive development and new technologies used within modern gas turbines. READ MORE

5. 24. Transient model of a driven compressor

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Rasmus Johnsson; Sebastian Norén; [2017]
   Keywords : Technology and Engineering;

   Abstract : Industrial gas turbines are widely used in different applications. These can be divided into two main categories; power generation (PG) and mechanical drive (MD). To be able to predict the performance of the system, Siemens has during the years developed simulation models for both steady state and transient operation. READ MORE

6. 25. 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
