“…To quantify the difference between the reference signal and the damage signal and extract damage features, the first set of five-period Lamb waves from both signals were studied. The correlation coefficient I i was calculated using equation (8) to describe the correlation between the two signals. The Lamb wave passing through the laminated plywood produces a scattering effect at the location of the delamination damage.…”

“…Wind power equipment is constantly developing towards large-scale direction, and the diameter of blades is constantly increasing [7]. The variety of airfoils is also expanding as they serve as the fundamental component of blade aerodynamic shape design [8]. The large wind turbine blades differ significantly from typical mechanical structures.…”

This investigation addresses the issue of damage detection and localization in wind turbine blade laminates. This paper proposes a novel approach that integrates the elliptical trajectory and probabilistic imaging method using the Bayesian framework. This method employs multiple damage-sensitive features to enhance the reliability and robustness of sensor arrays. The algorithm is optimized by analyzing the propagation characteristics of Lamb waves in composite blade laminates. A numerical simulation is conducted on a 1.5MW wind turbine blade laminate model, incorporating the scattered wave signal, wave arrival time, and correlation coefficient as damage characteristic signals. Markov Chain Monte Carlo (MCMC) sampling method is adopted to obtain the posterior distribution of the damage location and achieve accurate localization of blade delamination damage. The experimental results indicate that the damage localization algorithm, which utilizes the Bayesian approach, achieves an accuracy of approximately 97.04% in localizing delamination damage in blade laminates.

The objective of this study is to contribute to the research and development of vertical axis wind turbines (VAWTs). This will be achieved through a comprehensive analysis of modified airfoils featuring inclined cavities, specifically tailored for applications in wind systems but not limited to this. The investigation conducted in this manuscript utilizes computational fluid dynamics (CFD) to perform a numerical assessment of different airfoil configurations that have undergone modifications consisting of the incorporation of tilted cavities along distinct lengths of their upper surfaces. The aim is to ascertain an optimal airfoil geometry for VAWT applications, with a focus on concurrently achieving a high lift coefficient while minimizing the impact on the drag coefficient, therefore enhancing the overall aerodynamic performance of VAWTs. The airfoil employed in this study is the NACA0012, serving as a benchmark for comparison with airfoils subjected to modifications involving the incorporation of tilted cavities. The results of this investigation reveal that, in terms of aerodynamic traits, one of the altered airfoil configurations exhibits superior performance relative to the NACA0012 airfoil.
