  1. 1. Modeling of the trajectory of ice thrown from a wind turbine

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Elena Rocchi; [2023]
    Keywords : Ice thrown - Ice fall - RANS - LES - CFD - simulations - ballistic model; Technology and Engineering;

    Abstract : There is a growing number of wind turbines installed in cold temperature zones as a result of the restricted space for new construction. Due to ice deposition on the turbine blades, the increasing installation of wind turbines in freezing temperature areas presents many challenges: ice accumulation increases weight, unbalances the rotor, diminishes aerodynamic efficiency, and creates safety issues.

  3. 2. Analysis to reduce ice-related production losses for wind turbines

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

    Author : Jhason Paran De La Cruz; [2023]
    Keywords : Wind power; cold climate; wind turbine icing; ice losses; ice protection systems; blade heating; de-icing; analytical dashboard; data visualization.; Vindkraft; kalla klimat; nedisning av vindkraftverk; isförluster; isskyddssystem; uppvärmning av blad; avisning; analysverktyg; datavisualisering.;

    Abstract : In the rapidly growing wind energy market, regions with cold climates are currently in the spotlight owing to their abundance of wind resources. However, the operation of wind turbines in cold climate conditions is challenged by serious icing problems. READ MORE

  4. 3. An assessment of circular economy measures in the construction value chain for offshore wind turbines

    University essay from Lunds universitet/Byggproduktion

    Author : Therése Svensson; [2023]
    Keywords : Circular economy; Construction value chain; Wind energy; Offshore wind turbine; Offshore wind farm; Design; Manufacturing; Construction; Operation and maintenance; End of life; Technology and Engineering;

    Abstract : The construction sector is responsible for high energy consumption and large emissions of carbon dioxide, which is strongly linked to building materials. Within the European Union, the construction sector generates more than a third of all waste and circular economy is considered as a suitable approach to tackle these challenges. READ MORE

  5. 4. 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

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

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

    Author : Claudia Florentina Balan; [2022]
    Keywords : ;

    Abstract : 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.
