  1. 1. Wind-wave interaction effects on offshore wind energy

    University dissertation from Department of Energy Sciences, Lund University

    Author : Ali Al Sam; Lunds universitet.; Lund University.; [2016-11]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wind-wave; swell; atmospheric boundary layer; marine atmospheric boundary layer; atmospheric turbulence; Large-eddy simulation; actuator line; wind sea; offshore technology; wind energy; wind turbine; aerodynamic;

    Abstract : This thesis is devoted to the investigation of the impacts of fast moving ocean surface waves on the aerodynamics of offshore wind turbines. The impacts of non-locally generated waves (swell) on the Marine Atmospheric BoundaryLayer (MABL) and thereby on offshore wind turbine aerodynamics are studied numerically by using Large Eddy Simulations and the Actuator Line Method.

  2. 2. Numerical Computations of Wakes Behind Wind Farms

    University dissertation from Uppsala : Institutionen för geovetenskaper

    Author : Ola Eriksson; Uppsala universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Wind turbine; Wind power; Wind farm; Wakes; Long distance wakes; Farm-Farm; Farm to farm interaction; Wind farm cluster; Large Eddy simulations; LES; Actuator disc method; ACD; CFD; Ellipsys3D;

    Abstract : More and larger wind farms are planned offshore. As the most suitable build sites are limited wind farms will be constructed near to each other in so called wind farm clusters. Behind the wind turbines in these farms there is a disrupted flow of air called a wake that is characterized by reduced wind speed and increased turbulence. READ MORE

  3. 3. Numerical Computations of Wakes Behind Wind Farms A tool to study Farm to Farm interaction

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Ola Eriksson; Uppsala universitet.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Wind turbine; Wind power; Wind farm; Wakes; Long distance wakes; Farm-Farm; Farm to farm interaction; Wind farm cluster; Large Eddy simulations; LES; Actuator disc method; ACD; CFD; Ellipsys3D; Prescribed boundary layer; PBL; Forced boundary layer; FBL; Meteorologi; Meteorology;

    Abstract : More and larger wind farms are planned offshore. As the most suitable sites to build are limited these new wind farms will be constructed near to each other in so called wind farm clusters. Behind the wind turbines in these farms there is a disrupted flow of air called a wake that is characterized by reduced wind speed and increased turbulence. READ MORE

  4. 4. Wind power wake modelling Development and application of an actuator disc method for industrial utilization

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Nikolaos Simisiroglou; Uppsala universitet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Wind power; Offshore wind farm; Wakes; Actuator Disc Method ACD ; Computational Fluid Dynamics CFD ; Reynolds Average Navier–Stokes RANS ; WindSim; PHOENICS;

    Abstract : As a wind turbine extracts energy from the wind it creates a region downstream where the wind velocity is decreased and the urbulence intensity is increased, this region is commonly called the wake region. Today’s wind farms include a large number of wind turbines position in tight layouts. READ MORE

  5. 5. Finding the right place - The story about an offshore wind power project

    University dissertation from Göteborg : Göteborg University

    Author : Petter Rönnborg; Göteborgs universitet.; Gothenburg University.; [2006]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; decision-making; evaluation; goals; institutions; production logic; case study; renewable energy; wind power; offshore; transformation;

    Abstract : The Swedish parliament has committed the country to a strong development of renewable energy resources. The present political goal is to increase renewable electricity production with additional 10 TWh by 2010. READ MORE
