Structural Analysis of a NREL 5 MW Wind Turbine Exposed to Combined Aerodynamic and Tsunami Wake Forcing

Abstract

Wind turbines located in coastal areas are important for generating energy from renewable sources. However, due to environmental factors, their construction, analysis, and use are extremely difficult and complex. It is very difficult to examine the aerodynamic and hydrodynamic behavior of wind turbines in coastal areas, especially under natural events such as tsunamis. This study investigates the aerodynamic, hydrodynamic, and structural behaviors of the NREL 5 MW wind turbine positioned in the coastal region under the tsunami wake and wind effects. Firstly, the geometric properties of the NREL 5 MW wind turbine were determined, and its aerodynamic analysis was performed with the Blade Element Momentum (BEM) approach. Secondly, the tsunami wave elevations caused by the earthquake that occurred on August 30, 2020, were analyzed. The data required for this analysis were obtained from the UNESCO data portal located at the Bodrum station. Then, the wave elevation time series of the tsunami wakes were exposed to the NREL 5 MW wind turbine, and their hydrodynamic properties were analyzed. In addition, the aerodynamic properties of the wind turbine were also investigated under the influence of the wind acting on the wind turbine at the same time. QBlade software was used for the study. This study was conducted to make a significant contribution to future research on the behavior of wind turbines under natural events by performing aerodynamic, hydrodynamic, and structural analyses of a wind turbine exposed to tsunami wakes and wind effects.
