Hur, C. (author), Ferreira, Carlos (author), Schepers, Gerard (author)Horizontal axis wind turbines (HAWTs) experience yaw misalignments due to the physical limitations of yaw controllers and various novel active yaw controls. Moreover, the motion of floating offshore wind turbines (FOWTs) accelerates yaw misalignment. The blade element momentum (BEM) method is widely used due to its computational efficiency for...journal article 2022

Saleem, Zohaib (author)Passive root flaps and in particular the Gurney flaps have been employed for improving aerodynamic characteristics for various applications since the 1970's. The effects of passive flaps on two dimensional airfoils have therefore been studied extensively, however, research on their application to Horizontal axis wind turbine blades (HAWT) is...master thesis 2019

Vimanyu Kumar, Vimanyu (author)The growing importance of renewable energy to meet the demands of growing population has driven much focus for research in the wind energy sector. Currently most of the power production in the wind energy sector is done using the Horizontal Axis Wind Turbine (HAWT). due to its higher efficiency and reliability as compared to Vertical Axis Wind...master thesis 2017

Lignarolo, L.E.M. (author)The wake flow of a horizontal axis wind turbine is characterised by lower wind speed and higher turbulence than the free-stream conditions. When clustered in large wind farms, wind turbines regularly operate inside the wake of one or more upstream machines. This is a major cause of energy production loss and a source of higher fatigue loads on...doctoral thesis 2016

Micallef, D. (author), Simao Ferreira, C.J. (author), Sant, T. (author), Van Bussel, G.J.W. (author)The main motivation behind this work is to create a purely analytical engineering model for wind turbine wake upward deflection due to shear flow, by developing a closed form solution of the velocity field due to an oblique vortex ring. The effectiveness of the model is evaluated by comparing the results with those of a free-wake model. The...conference paper 2010
