  1. 1. Forced response numerical investigation of a transonic compressor rotor

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Mariana Pires Gonçalves Toco Dias; [2023]
    Nyckelord :Compressor; rotor; blisk; aeroelasticity; aerodynamic damping; CFD; transient; forced response;

    Sammanfattning : The present thesis discusses the forced response of a rotor’s bladed-disk when excited by the periodic force produced by a wake generator, or Inlet Guide Vane (IGV),with 8 equally-spaced blades. These components are part of an axial transonic compressor rig, moreover the Transonic Compressor Darmstadt 1 (TCD1), located at the Technical University of Darmstadt. LÄS MER

  3. 2. Turbulence Intensity Measurements in a High-Pressure Gas Turbine Stage

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Ettore Scami; [2022]
    Nyckelord :Turbulence Intensity; turbine; stage efficiency; grid; turbomachinery; length scales;

    Sammanfattning : This Thesis work focused on the acquisition and evaluation of data on mean velocity, turbulence intensity and length scales obtained via hot wire measurements in a high pressure single-stage land-based turbine available at the Department of Heat and Power Technology in KTH. Turbulence was generated by the use of grids and twoprobes, upstream and downstream of the turbine stage, were used. LÄS MER

  4. 3. Process monitoring of turbine blades : Monitoring of blade tip clearance using eddy current sensors

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Hampus Andersson; [2022]
    Nyckelord :Blade tip clearance; Blade tip timing; Eddy current sensor; Turbine monitoring; Maintenance.; Bladtoppspel; Bladvibrationer; Eddy current sensorer; Turbinövervakning; Underhåll.;

    Sammanfattning : This thesis has been a collaboration between the Royal Institute of Technology (KTH) and Siemens Energy which invest in the research facility at KTH. The objective was to investigate the use of eddy current sensors in real-time monitoring of turbine blades. LÄS MER

  5. 4. CFD validation of a new gas turbinestage design with experimental data

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Claudia Florentina Balan; [2022]
    Nyckelord :;

    Sammanfattning : Gas turbines are present in two energy-intensive sectors: aviation and energy production. Improving the efficiency of gas turbines has a huge impact on the reduction of CO2 in the atmosphere, therefore many research groups are studying innovative strategies to improve the performance of these turbines.

  7. 5. Correlation of numerical simulation methods and failure criteria to experimental burst test

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Hållfasthetslära

    Författare :Karlo Kasljevic; [2020]
    Nyckelord :Gas; Rotor; Turbine; Overspeed; Burst; Test; Strength; Analysis; Failure; Criteria; Burst margin; Stress analysis; Finite element method; Rotating disc; Burst Strength; Turbine disc; turbo-engine disk; Fracture; Blisk; Correlation study; Technology and Engineering;

    Sammanfattning : Predicting the burst speed of turbine rotors is a costly and challenging task. Therefore, the scope of this thesis is to perform a correlation study between numerical simulation methods and failure criteria to experimental over-speed burst test of the Prometheus turbine rotor.
