Active damage mitigation of the blade leading edge erosion for a wind turbine during rainfall events
RIPOLL, ÁLVARO ÚBEDA; Jiang, Zhiyu; Verma, Amrit Shankar; Zhou, Jing (Peer reviewed; Journal article, 2023)Leading edge erosion (LEE) of wind turbine blades is a major concern for the wind turbine industry. LEE leads to increased blade surface roughness and incurs significant repair and maintenance costs. To address this issue, ... -
Comparison of numerical modelling techniques for impact investigation on a wind turbine blade
Verma, Amrit Shankar; Vedvik, Nils Petter; Haselbach, Philipp Ulrich; Gao, Zhen; Jiang, Zhiyu (Journal article; Peer reviewed, 2019)Wind turbine blades are exposed to numerous impact risks throughout their lifetimes. The impact risks range from bird collisions during operation to impacts with surrounding structures at the time of transportation and ... -
