  1. 11. 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. 12. Validation of one-dimensional loss models for axial gas turbines

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Kim Hirsch; Ramin Moghadam; [2016]
    Keywords : gas turbine; loss model; turbine; Technology and Engineering;

    Abstract : Denna masteruppsats är ett sammarbete mellan Siemens Industrial Turbomachi- nery (SIT) och Lunds Tekniska Högskola (LTH). Uppsatsen berör validering av ett nytt in-house verktyg på SIT som heter ”Mean Line Tool” (MLT), framför allt sekundärförlustmodellerna som verktyget använder. READ MORE

  4. 13. Parameter selection and derivative conditions for B-splines applied to gas turbine blade modeling

    University essay from Lunds universitet/Matematik LTH

    Author : Andreas Söderlund; [2015]
    Keywords : B-splines; spline interpolation; parameter selection; knot selection; Bezier curves; NURBS; derivative conditions; geometric continuity; turbine blade; turbine; compressor; compressor blade; interpolation; Mathematics and Statistics;

    Abstract : In gas turbine blade modeling a stable but yet flexible method of describing the blade shape is crucial. Polynomials and B ́ezier curves have previously been used and in this paper B-splines are employed instead. READ MORE

  5. 14. Effect of Axial Gap Distance on Transonic Compressor Performance

    University essay from KTH/Kraft- och värmeteknologi

    Author : Joseph Sadek; [2015]
    Keywords : Axial Gap Distance; Transonic Compressors; Aerodynamic Performance; CFD; Harmonic Balance; inter-row gap;

    Abstract : The modern trend of gas turbines design is towards lighter, highly efficient,and more compact engines. Such situation imposes on engineers to continuouslysearch for improved and optimum designs. The thesis presented aims at researching possible performance improvements regarding axial gapdistance in transonic compressors. READ MORE
