  1. 1. Noise, eigenfrequencies and turbulence behavior of a 200 kW H-rotor vertical axis wind turbine

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Erik Möllerström; Uppsala universitet.; Högskolan i Halmstad.; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära; VAWT; H-rotor; eigenfrequency; semi-guy-wired tower; noise emission; sound power level; microphone array; turbulence intensity; power curve;

    Sammanfattning : Vertical-axis wind turbines (VAWTs) have with time been outrivaled by the today more common and economically feasible horizontal-axis wind turbines (HAWTs). However, VAWTs have several advantages which still make them interesting, for example, the VAWTs can have the drive train at ground level and it has been argued that they have lower noise emission.

    Sammanfattning : Vertical axis wind turbines (VAWTs) have with time been outrivaled by the today common and economically feasible horizontal axis wind turbines (HAWTs). However, VAWTs have several advantages such as the possibility to put the drive train at ground level, lower noise emissions and better scaling behavior which still make them interesting for research.
