  1. 6. Validation of a vortex panel method for aerodynamics and aero-elasticity of Wind Turbine

    University essay from KTH/Kraft- och värmeteknologi

    Author : Antoine Thibierge; [2018]
    Keywords : ;

    Abstract : Ardema3D is a new type of vortex free model code that can simulate wind turbines. This code has been developed in order to replace the state of the art model, the blade element momentum (BEM). READ MORE

  3. 7. Verication of a Modelica Helicopter Rotor Model Using Blade Element Theory

    University essay from Linköpings universitet/Fluida och mekatroniska system

    Author : Jorge Luis Lovaco; [2017]
    Keywords : ;

    Abstract : Helicopters have been valuable vehicles ever since their invention. Their capabilities for axial flight and hovering make them an outstanding resource. However, their complexity, directly related to their aerodynamics, makes them extremely hard to design. READ MORE

  4. 8. 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

  5. 9. Validation of CFD simulation with PIV measurements for Open Rotor Noise Predictions

    University essay from KTH/Mekanik

    Author : THOMAS JEAN BERNARD POMMIER; [2015]
    Keywords : ;

    Abstract : CROR means Contra--‐Rotating Open Rotor. Its efficiency is better than usual in aeronautics thanks to its geometry (open rotor and thus high bypass ratio) but also by adding a second rotor. Indeed it enables to recover the swirl loss of the first rotor. However, this engine is rarely used today in civil aviation for acoustic reasons. READ MORE

  6. 10. 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
