Leading edge erosion of wind turbine blades: Effects of blade surface curvature on rain droplet impingement kinematics
Verma, Amrit Shankar; Castro, Saullo GP; Jiang, Zhiyu; Hu, Weifei; Teuwen, Julie JE (Peer reviewed; Journal article, 2020)The issue of leading edge erosion (LEE) of wind turbine blades (WTBs) is a complex problem that reduces the aerodynamic efficiency of blades, and affects the overall cost of energy. Several research efforts are being made ... -
Life cycle cost analysis of a floating wind farm in the Norwegian Sea
Bjørni, Fredrik Andersen; Lien, Sverre; Midtgarden, Torjus Aasrum; Santos, Laura-Castro; Jiang, Zhiyu (Peer reviewed; Journal article, 2023)The offshore wind energy industry has witnessed rapid growth in the past decade. Still, there is a lack of commercial floating wind projects due to the relatively high development costs and other factors. To facilitate the ... -
Life Cycle Cost Analysis of a Floating Wind Farm Located in the Norwegian Sea
Bjørni, Fredrik Andersen; Lien, Sverre; Midtgarden, Torjus Aasrum (Master thesis, 2023)This thesis aims to investigate the levelized cost of energy of an offshore floating wind farm, as well as evaluate its financial feasibility.
