  1. 21. The impact of wind conditions on wind turbines

    University essay from KTH/Energiteknik

    Author : Lovisa Eriksson Petersen; [2016]
    Keywords : ;

    Abstract : The world is facing global warming and the challenge to reduce greenhouse gas emissions. Wind power is a renewable source of energy with no greenhouse gas emissions when operating. Therefore, it could contribute in this challenge. READ MORE

  3. 22. A stochastic analysis of Turbulence Intensity influence over various sizes of HAWT : Study of hypothetical relationship between Rotor Diameter and influence level of Turbulence Intensity

    University essay from Högskolan i Halmstad/Energivetenskap

    Author : Allen Christo Nicholas; [2016]
    Keywords : Turbulence intensity; power performance; power deviation; power coefficient; tip speed ratio.; Turbulensintensitet; effektuttag; effektavvikelse; verkningsgrad; löptal;

    Abstract : This disquisition aims for the study of turbulence intensity influence over the power performance of different sizes of turbines with the intent to validate a hypothesis. The hypothesis formulated for the analysis is the relationship between the rotor diameter (turbine size) and turbulence intensity. READ MORE
