Architecting a digital twin for wind turbine rotor blade aerodynamic monitoring
in Frontiers in Energy Research, 12, 1428387 , 2024 Digital twins play an ever-increasing role in maximising the value of measurement and synthetic data by providing real-time monitoring of physical systems, integrating predictive models and creating actionable insights. This paper presents the development and implementation of the Aerosense digital twin for aerodynamic monitoring of wind…
A Self-Sustainable and Micro-Second Time Synchronised Multi-Node Wireless System for Aerodynamic Monitoring on Wind Turbines
in IEEE Access, vol. 11, pp. 119506-119522, 2023 Wind energy generation plays a vital role in transitioning from fossil fuel-based energy sources and in alleviating the impacts of global warming. However, global wind energy coverage still needs to rise, while requiring a significant step up in conversion efficiency: monitoring wind flow and operational parameters of…
Hybrid Model for Inflow Conditions Inference on Airfoils Under Uncertainty
in AIAA Journal, vol. 61, no. 11, pp. 4913-4925, 2023 Estimation of inflow conditions, such as wind speed and angle of attack, is vital for assessing aerodynamic performance of a lifting profile. This task is particularly challenging in the field due to the inherent stochasticity of the inflow variables. In practice, the field installation of…
Instrumentation and Measurement Systems: Aerosense: A Wireless, Non-Intrusive, Flexible, and MEMS-Based Aerodynamic and Acoustic Measurement System for Operating Wind Turbines
in IEEE Instrumentation & Measurement Magazine, vol. 26, no. 4, pp. 12-18, 2023 Wind energy as a renewable energy source has gained in popularity in recent years as a viable means to replacing fossil fuels. Wind turbines form extremely sophisticated systems, operating under extreme and time-varying loads of polymorphic nature (e.g., wind, waves) and under…
Development of a wireless, non-intrusive, MEMS-based pressure and acoustic measurement system for large-scale operating wind turbine blades
in Wind Energy Science, 7(4):1383-1398, 2022 As the wind energy industry is maturing and wind turbines are becoming larger, there is an increasing need for cost-effective monitoring and data analysis solutions to understand the complex aerodynamic and acoustic behaviour of the flexible blades. Published measurements on operating rotor blades in real conditions are very scarce…
