The one-way fluid-structure interaction was used to combine the aerodynamics of the VAWT and the structural characteristics of a single blade.
In this paper, the NREL 5MW wind turbine blades are modeled with accurate 3D lay-up design, firstly, based on the joint simulation of commercial software STAR CCM+ and ABAQUS, the two-way fluid-solid coupling technology, the wind turbine under uniform wind condition is simulated, and the results from thrust, torque, structural deformation and force perspective and FAST are compared with good accuracy and consistency below the rated wind speed. The results show that the turbulence intensity has a greater impact on the amplitude of the wind turbine blade, and the stress distribution of the blade is more concentrated, which in turns affects the stability and safety of the wind turbine blade and is not conducive to the normal operation of the wind turbine. With the increase in wind turbine blade size, the deformation of the blade is getting larger and larger, and the deformation of the blade has a greater impact on the local distribution of the flow field, aeroelasticity becomes an important part of the optimal design of the blade.

WEBINAR | Development of an Aero-Servo-Elastic Module for the Next Generation of Wind Turbines convergecfd 5520 subscribers 3 likes 309 views 16 Feb 2024 Presented by: Leonardo Pagamonci, Ph.D. Candidate, University of Florence Investigating aeroelasticity is a key challenge in the design of next-generation wind turbine systems. Computational fluid dynamics (CFD) can provide meaningful insight into the phenomenon by either resolving the blade aerodynamics or modeling them using a hybrid method. The actuator line model (ALM), one example of a hybrid method, blends a high-fidelity CFD solution of the flow field with blade element aerodynamics. In this webinar, guest speaker Leonardo Pagamonci from the University of Florence discusses the development and implementation of an aero-servo-elastic module, CALMA (CONVERGE Actuator Line Model for Aeroelasticity), into CONVERGE CFD software. CALMA couples CONVERGE with the engineering software OpenFAST; in this framework, CONVERGE solves for the flow field, while OpenFAST calculates the aerodynamic and structural response of the turbine through ALM. Leonardo highlights the main results from his studies using CALMA and discuss future applications of the tool.
