  1. 1. Wake velocity deficit calculation and wind turbine separation in the forested area using RANS

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Semion Zubov; [2022]
    Keywords : RANS; wakes; forest;

    Abstract : Wake has a high impact on wind turbine performance and durability. Its impact, without a doubt, should be considered in wind resource assessment. However, wakes in the forest is a niche that is only examined by a couple of countries which area has a significant per cent land covered in forests. READ MORE

  3. 2. Wake analysis for NACA4412 in free-flight condition

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : William Nord Nilsson; Oskar Hedström; [2021]
    Keywords : ;

    Abstract : The purpose of this project is to evaluate the differences in the wake of a NACA 4412 airfoil in free-flight condition compared to wind tunnel and also investigate wall-interference. This was done using two sets of angles of attack, 5 degrees and 8 degrees. READ MORE

  4. 3. 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

  5. 4. WAKE INDUCED POWER DEFICIT ANALYSIS ON WIND TURBINES IN FORESTED MODERATELY COMPLEX TERRAIN USING SCADA DATA

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Esma Öztürk; [2018]
    Keywords : turbine wakes; wake interaction; wake losses; power deficit; SCADA data;

    Abstract : Over the last few decades, wind power has shown a continuous and significant developmentin the energy market globally. Having reached a certain level in both technologyand in dimensions, the role of optimizing wind turbines as well as wind farms hasbecome an additional aspect to future development and research.

  6. 5. Meteorological Conditions on Nordenskiöldbreen Glacier, Svalbard (2009 – 2015)

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Niclas Bergman; [2017]
    Keywords : Svalbard; Nordenskiöldbreen; glacier; albedo; Svalbard; Nordenskiöldbreen; glaciär; albedo;

    Abstract : Glacial environments in the Arctic are a much-studied topic as well as a field of research with strong influences regarding the current and future global climate of our planet. This report is focused on the meteorological conditions on Nordenskiöldbreen glacier from 2009-2015 and how they correlate with each other, the glacier surface and the surrounding terrain. READ MORE
