  1. 11. Aeroelastic instabilities simulations on turbofan HP compressorblisk at surge-like reversed flow conditions

    University essay from KTH/Flygdynamik

    Author : Raphael Murray; [2013]
    Keywords : ;

    Abstract : This paper presents the work done at the High Pressure Compressor design division of Safran Snecma to simulate the flutter behaviour of a compressor blisk at reversed flow conditions. The report states the preliminary phase of modelling the reversed flow on an entire compressor with a stationary simulation and the single blade aeroelastic study results obtained. READ MORE

  3. 12. Multi-Body Unsteady Aerodynamics in 2D Applied to aVertical-Axis Wind Turbine Using a Vortex Method

    University essay from Elektricitetslära

    Author : David Österberg; [2010]
    Keywords : wind power vertical flow;

    Abstract : Vertical axis wind turbines (VAWT) have many advantages over traditional Horizontalaxis wind turbines (HAWT).One of the more severe problem of VAWTs are the complicated aerodynamicbehavior inherent in the concept. Incontrast to HAWTs the blades experience varying angle of attack during its orbitalmotion. READ MORE

  4. 13. 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

  5. 14. Investigation of rotor downwash effects using CFD
