“…Areas with initial surface defects could lead to earlier failure, even for smaller tip speeds, and generate scatter in tip speed -impacts to failure (V-N) curves obtained from RET. Voids within the volume of the coating layer could have the same effect on V-N curves, by creating stress concentrations and leading to early failure [43]. The elevated stress values inside erosion pits and surface irregularities, predicted by the Finite Element models used in this study, could explain the faster erosion rates in damaged areas observed in the experiments, as well as damage initiating from pre-existing surface defects.…”

Leading edge erosion of wind turbine blades is the most often observed damage mechanism of wind turbines. The surface erosion of blades is influenced by many multiphysics and stochastic factors including humidity and related degradation processes, rough uneven surface and roughness development, random defects in the materials. In this paper, the effects of these factors and possibilities of their computational modelling and prediction are discussed. Competing damage mechanisms in erosion, including debonding and impact damage, as well moisture ingress and weathering are investigated. A predictive model for roughness evolution of leading edge due to the surface damage is presented.

“…Blade coating materials will also affect the life of blades. Kuthe et al [11] determine the local stress distribution in the coating by establishing a finite element model and study the stress concentration of different blade materials by calculating experiments so as to determine the appropriate coating materials to effectively cope with the impact and prolong the life of the coating.…”

In the Inner Mongolia region, sand and dust storms are prevalent throughout the year, with sand erosion having a particularly significant impact on the performance of wind turbine blades. To enhance the performance stability of wind turbines and reduce operation and maintenance costs, this study delves into the specific impact of sand-laden wind erosion on the aerodynamic performance of scaled-down wooden wind turbine blades. The experiment conducts vehicle-mounted tests on scaled models of 1.5 MW wind turbine blades that have been eroded by wind-sand flows from different zones, analyzing the changes in aerodynamic performance of wind turbines caused by the erosion. The results indicate that with an increase in the angle of installation, both the overall power output and the wind energy utilization coefficient of the wind turbines show a declining trend. The power outputs of both the partially eroded group and the fully eroded group are unable to reach the rated power level of 100 W. Compared to the uneroded group, the leading-edge eroded group demonstrated higher power output and wind energy utilization coefficients across most wind speed ranges. This finding verifies the possibility that the drag-reducing effect caused by pits from leading-edge erosion has a positive impact on the aerodynamic performance of the blades. It also provides a new research perspective and strong evidence for the study of erosion effects on wind turbine blades and the optimization of their aerodynamic performance.
