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

    University essay from KTH/Skolan för industriell teknik och management (ITM)

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

    Abstract : 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. READ MORE

  3. 2. Experimental Investigation of the Aerodynamics of a Sailing Cargo Vessel with Four Rigid Wingsails under Unsteady Sailing Conditions

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Antonia Hillenbrand; [2022]
    Keywords : Experimental Aerodynamics; Pressure measurements; Sailing; Scale model testing; Trimming; Sea trial; Experimentell aerodynamik; Tryckmätning; Segling; Testning av skalamodeller; Trimning; Sjöprovning;

    Abstract : Wind propulsion is a traditional way to propel ships over the oceans. In the recent development towards more sustainable shipping, sailing is considered in the industry again with high momentum. For a modern merchant ship, the aerodynamic forces generated on the particular rigging are unusual. READ MORE

  4. 3. Numerical evaluation of the ground vortex

    University essay from KTH/Teknisk mekanik

    Author : Martin Babo; [2022]
    Keywords : Turbofan engine; CFD; Flow simulation; Ground Vortex; External aerodynamics;

    Abstract : This master thesis covers the realization of a CFD calibration study regarding the numerical simulation of the ground vortex phenomenon. As part of InVIGO project (EU CleanSky2), wind tunnel test campaigns were performed using a nacelle model combined with a movable raised floor. READ MORE

  5. 4. Load Control Aerodynamics in Offshore Wind Turbines

    University essay from KTH/Kraft- och värmeteknologi

    Abstract : Due to the increase of rotor size in horizontal axis wind turbine (HAWT) during the past 25 years in order to achieve higher power output, all wind turbine components and blades in particular, have to withstand higher structural loads. This upscalingproblem could be solved by applying technologies capable of reducing aerodynamic loads the rotor has to withstand, either with passive or active control solutions. READ MORE

  6. 5. Investigating the aerodynamic performance of an UAV

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Bala Murali Krishna Gummadi; Rahul Rajan Sourirajan; [2021]
    Keywords : Computational Fluid Dynamics; Aerodynamics; Flight Stability;

    Abstract : The aerodynamic performance of any airborne vehicle is an important characteristic to be considered during the concept development process. Lift and drag forces are the two most important aspects of aerodynamics that dictates vehicle efficiency. READ MORE
