6. Partially Parabolic Wind Turbine Flow Modelling
University essay from KTH/MekanikAbstract : Climate change is an evermore urging existential treat to the human enterprise. Mean temperature and greenhouse gas emissions have in-creased exponentially since the industrial revolution. But solutions are also mushrooming with exponential pace. READ MORE

7. CFD calculations and comparison with measured data in a film cooled 1.5 stage high pressure test turbine : With two configurations of swirlers clocking
University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Abstract : The gas turbine has an important role for the energy distribution due to its stability and flexibility. By increasing turbine inlet temperature (TIT) an increased thermal efficiency of the turbine can be achieved. The biggest limitation of the TIT is the material of the turbine components. READ MORE

8. CFD Analysis of Pressure Instabilities in Stator-Rotor Disc Cavity Systems
University essay from Linköpings universitet/Mekanisk värmeteori och strömningsläraAbstract : The continuous demand to improve turbine performance has led manufactures to focus on aspects that have been previously considered of secondary importance such as the secondary air system. The purpose of this system is to cool the components and prevent ingestion of hot gas into the stator-rotor cavity that could lead to low frequency pressure fluctuations called Cavity Flow Instabilities.

9. Investigation and Validation of Cooling Loss Models for Axial Gas Turbines
University essay from KTH/EnergiteknikAbstract : 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

10. Highly loaded HPT blading in KTH test turbine - An attempt to reduce the number of blades in the first stage in a high pressure turbine
University essay from Lunds universitet/Institutionen för energivetenskaperAbstract : The main goal with this thesis was to investigate the possibility to reduce the number of blades in a high pressure gas turbine row. The reason for this study was the interest to reduce the amount of cooling air needed within the blade row by reducing the wetted area, hopefully without losing efficiency. READ MORE
