Multi-physics Modelling of Erosive Impact of Particles on Wind Turbine Blades

The "PARTIMPACT" project tackled a long-standing research challenge of predicting damage due to particle impacts on surfaces. The project primarily aimed to develop precise models for simulating the impact of solid and liquid particles on Wind Turbine Blades (WTBs), including accurate estimation of resulting damage and Leading Edge Erosion (LEE). With wind power's rapid growth, large wind turbine blades face the dual challenge of maintaining lift and countering airborne particles induced erosion. The erosion worsens surface roughness, impacting aerodynamic performance and structural integrity, leading to downtime and maintenance costs. The project aimed to address these issues by creating predictive models for particle impact erosion and optimizing materials during the design phase. The MSCA Fellow addressed the research challenge by identifying the components needed and coupled the DEM/SPH methods for modelling solid/liquid particles with PD theory and implemented the solution to the logical architecture of the final software. This modeling approach brings together the unique capabilities of PD and DEM/SPH and has the potential to make use of the various contact laws, which allow the development and adjustment of relevant contact forces. This technique also allows to incorporate damping effects, friction, and intra-particle stiffness through DEM and fluid viscous effects through SPH into the simulations. The characteristics of the target material are described by the integrodifferential equations of the PD theory, which is the best-known technique for modeling solids with discontinuities, such as cracks. The proposed method has been used for modeling material failure of brittle and laminated targets after being validated and verified for the contact parameters during the impact process. The present model is successfully applied to model the LEE due to the impact of airborne particles on the leading edge of WTB. We performed a series of tests to determine how the particle size, impact angle, and impact velocity of the impinging particles alter the response of the leading edge coating system. Moreover, mass removal and the mean displacement of the target material points are reliably calculated using the hybrid PD-DEM/SPH method.

Цел на проекта

The main focus of this proposal is to accurately model the damage to the wind turbine blades due to impacts by solid (e.g. hailstone) or liquid (e.g. rain droplet) ""particles"". The applicant will pioneer a new multi-physics computational framework to transform the current semi-empirical computational fluid dynamics (CFD)-based approaches. This new research tool will then be used to answer the main research question which is to understand the dynamical role of impinging particles – liquid or solid – in the erosion process, enabling quantitative prediction of the erosive impact of particles and mass removal rate from the surfaces. The main modeling challenge is to present both solid and liquid particles in a unified theoretical framework. Therefore, the applicant will develop a generalised peridynamics theory to predict the damage by both solid and liquid particles and implement it in a validated opensource Software platform. The applicant will collaborate with Strathclyde University (STRATH) and the Manufacturing Technology Centre (MTC) to deliver the objectives, expand his professional network, and exchange knowledge with industrial stakeholders. The impact of the project is far-reaching: from reducing the costs of wind energy by preventing catastrophic turbine failure to meet the EU target of 240-450 GW of wind energy by 2050, to increasing public awareness on the importance of wind energy and asset management of aging infrastructures.The host (University of Edinburgh), the supervisor, and the project partners STRATH and the MTC are dedicated to the research and will provide all the necessary equipment, software licenses, and office space so ensure the delivery of the objectives. Furthermore, they will provide training in the required technical and soft skills to prepare the applicant to become a leader in modeling erosion due to particle impact, particle-laden and multiphase flow systems, and more broadly in wind energy.""
