  1. 16. STRUCTURAL ANALYSIS OF TRUSS CONSTRUCTION FOR WIND TURBINE BLADES

    University essay from Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Byggnadsmekanik

    Author : Björn Weddig; [2016]
    Keywords : Wind turbine blade; FRP; Truss system; Instability; Buckling; Non-Linear; Eigenvalue problem; Frequency response analysis; Transient dynamic response; Technology and Engineering;

    Abstract : The usage of wind turbines during the latest years has grown substantially and are becoming an increasingly important source of renewable energy, as many countries are trying to reduce their reliance on fossil fuels. In order to increase the effect of the wind turbines the length of the blades has been increased, which has also led to an increase of the cross-section dimensions. READ MORE

  2. 17. Non-dimensional gradient functions for water vapor and carbon dioxide in the marine boundary layer

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Caroline Vahlberg; [2015]
    Keywords : Monin-Obukhov similarity theory; non-dimensional gradient functions; water vapor; carbon dioxide; marine boundary layer; turbulent fluxes; Monin-Obukhov similaritetsteori; dimensionslösa gradientfunktioner; vattenånga; koldioxid; marina gränsskiktet; turbulenta flöden;

    Abstract : A better understanding of the exchange processes taking place over the oceans is of great importance since the oceans cover about 70 % of the Earth’s surface. With better knowledge the turbulent fluxes can be more accurate parameterized, which is essential in order to improve the weather- and climate models. READ MORE
