  1. 1. Wake velocity deficit calculation and wind turbine separation in the forested area using RANS

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Semion Zubov; [2022]
    Keywords : RANS; wakes; forest;

    Abstract : Wake has a high impact on wind turbine performance and durability. Its impact, without a doubt, should be considered in wind resource assessment. However, wakes in the forest is a niche that is only examined by a couple of countries which area has a significant per cent land covered in forests. READ MORE

  3. 2. Numerical study of the effects of wind-tunnel conditions on a passenger vehicle in crosswinds

    University essay from KTH/Teknisk mekanik

    Author : Sahil Gupta; Vivek J Shah; [2020]
    Keywords : ;

    Abstract : Wind tunnel tests is a necessity when it comes to study of aerodynamic flow field around vehicle in its development process. However, there are certain limitations on physical wind tunnel tests during vehicle development process. This includes high running costs and interference effects due to blockage and boundary conditions. READ MORE
