Stoevesandt, B. (author), Schepers, J.G. (author), Sun, Y. (author), Fuglsang, P. (author)Wind turbine aerodynamics remains to be a central field in the development of wind turbines. It comprises several aspects, and methods to be understood really make the best use of it in today’s wind turbine and wind farm development. This chapter gives an overview of all aspects in wind energy aerodynamics covered within this book and the...bookPart 2021

Rahimi, H. (author), Garcia, A.M. (author), Stoevesandt, B. (author), Peinke, J. (author), Schepers, J.G. (author)This work presents a significantly improved engineering model for the prediction of the loads in yawed flow. The newly developedmodel focuses on the so-called skewedwake effect. This effect leads to an azimuthal variation of the axial induction velocity which depends on the yawangle, tip speed ratio,wind speed, andradial position.Theazimuthal...article 2018

(author), Schepers, J.G. (author), Sorensen, N. (author), Stoevesandt, B. (author), Weihing, P. (author)Since the investigation of van Ingen et al., attempts were undertaken to search for laminar parts within the boundary layer of wind turbines operating in the lower atmosphere with much higher turbulence levels than seen in wind tunnels or at higher altitudes where airplanes usually fly. Based on the results of the DAN-Aero experiment and the...conference paper 2018

(author)This paper presents final results from the EU project AVATAR in which aerodynamic models are improved and validated for wind turbines on a scale of 10 MW and more. Special attention is paid to the improvement of low fidelity engineering (BEM based) models with higher fidelity (CFD) models but also with intermediate fidelity free vortex wake (FVW...conference paper 2018

Dose, B. (author), Rahimi, H. (author), Stoevesandt, B. (author), Peinke, J. (author), Schepers, J.G. (author)This work is aimed to investigate the effects of elastic blade deformations on the aerodynamics of large wind turbine rotors subjected to yawed inflow. Due to the increasing rotor size and advanced light weight blade designs, significant blade deflections can be observed on a regular basis for modern wind turbines. However, especially for...conference paper 2018
