  1. 1. Ride The Wind Symbiotic Business Model Innovation for the Chinese Wind Power Industry

    University dissertation from Halmstad : Halmstad University Press

    Author : Lihua Liu; Högskolan i Halmstad.; [2019]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Symbiotic Business Model; Business Model Innovation; Wind Power Innovation; China; Goldwind; 共生的商业模式,商业模式创新,中国,风电行业创新,金风科技;

    Abstract : China has become one of the world’s leading countries in renewable energy, particularly in wind power. Goldwind Science and Technology has become not only the largest wind turbine manufacturer in China, but also one of the largest in the world. READ MORE

  2. 2. Fluid Mechanics of Vertical Axis Turbines Simulations and Model Development

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Anders Goude; Uppsala universitet.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wind power; Marine current power; Vertical axis turbine; Wind farm; Channel flow; Simulations; Vortex model; Streamtube model; Control system; Graphics processing unit; CUDA; Fast multipole method; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : Two computationally fast fluid mechanical models for vertical axis turbines are the streamtube and the vortex model. The streamtube model is the fastest, allowing three-dimensional modeling of the turbine, but lacks a proper time-dependent description of the flow through the turbine. READ MORE

  3. 3. Wind Power and Natural Disasters

    University dissertation from Uppsala : Uppsala universitet

    Author : Jon Olauson; Uppsala universitet.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wind power; Natural disasters; Hybrid energy system; Meteorological model; Statistical model; Variability; Wind power integration;

    Abstract : Wind power can be related to natural disasters in several ways. This licentiate thesis gives some background and introduces four papers devoted to two aspects of this relation. The first section looks into how small-scale wind energy converters (WECs) could be used to generate power after a natural disaster. READ MORE

  4. 4. 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

  5. 5. 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
