  1. 1. 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)

    Author : Ellen Hallbäck; [2018]
    Keywords : Turbine; CFD; Clocking configuration; Turbin; CFD; virvlareposition;

    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

  3. 2. 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 energivetenskaper

    Author : Magnus Persson; [2015]
    Keywords : Highly loaded blading; High pressure turbine; Industrial gas turbine; Zweifel coefficient; Cooling; Reduce the number of blades; Technology and Engineering;

    Abstract : 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

  4. 3. Simplification of 3d cooled turbine blade models for efficient dynamic analyses

    University essay from KTH/Kraft- och värmeteknologi

    Author : Arokia Arokia Lourdu Marshall; [2013]
    Keywords : SGT-750; Cooled turbine blades;

    Abstract : In gas turbines, the temperature behind the combustors is the highest, meaning that the blades in the first stage of the turbine require cooling air. This makes the structural blade model very detailed due to the presence of the cooling pattern. READ MORE

  5. 4. Measuring routines of ice accretion for Wind Turbine applications : The correlation of production losses and detection of ice

    University essay from Institutionen för fysik

    Author : Viktor Carlsson; [2010]
    Keywords : wind power; atmospheric icing; anti icing; de-icing; icing sensors; icing measurements; relative humidity;

    Abstract : Wind power will play a major role in the future energy system in Sweden. Most of the major wind parks are planned to be built in sites where the cold climate and atmospheric icing can cause serious problems. This underlines the importance of addressing these issues. READ MORE

  6. 5. Oxidation and degradation of nickel-base alloys at high temperatures

    University essay from KTH/Materialvetenskap

    Author : Frans Palmert; [2009]
    Keywords : oxidation; nickel; nickel-base; superalloy; PWA1483; IN792; turbine; cyclic; spalling; hardness; gamma prime; coarsening; degradation; microstructure;

    Abstract : This master’s thesis work is a study of oxidation and degradation of nickel-base alloys at high temperatures. The materials studied are designed for use in critical gas turbine components such as turbine blades and vanes. Some of the alloys are used today, whereas others have not yet entered commercial application. READ MORE
