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

Ashuri, T. (author), Van Bussel, G.J.W. (author), Zaayer, M.B. (author), Van Kuik, G.A.M. (author)The purpose of this paper is to integrate the controller design of wind turbines with structure and aerodynamic analysis and use the final product in the design optimization process (DOP) of wind turbines. To do that, the controller design is automated and integrated with an aeroelastic simulation tool. This integrated tool is linked with an...conference paper 2010

Akay, B. (author), Simao Ferreira, C.J. (author), Van Bussel, G.J.W. (author), Tescione, G. (author)A detailed quantitative description of the aerodynamics of a horizontal axis wind turbine (HAWT) is difficult due to complexity of the flow field. Several methods from experimental to analytical are used to investigate the aerodynamics of a HAWT. In the present study, a wind tunnel experiment and computational fluid dynamics (CFD) simulations...conference paper 2010

Ashuri, T. (author), Van Bussel, G.J.W. (author), Zaayer, M.B. (author), Van Kuik, G.A.M. (author)A wind turbine blade has a complex shape and consists of different elements with dissimilar material properties. To do any aeroelastic simulation, the structural properties of the blade such as stiffnesses and mass per unit length should be known in advance, and extracting these properties is a difficult task. This paper presents an analytical...conference paper 2010

Savenije, L.B. (author), Ashuri, T. (author), Van Bussel, G.J.W. (author), Staerdahl, J.W. (author)The installation of floating wind farms in deeper water is encouraged by the stronger and steadier wind, the lower visibility and noise impact, the absence of road restrictions, but also the absence or shortage of shallow water. In the summer of 2009, the first large-scale floating wind turbine ”Hywind” was installed. Hywind is a spar-buoy...conference paper 2010

Micallef, D. (author), Kloosterman, M. (author), Ferreira, C.S. (author), Sant, T. (author), Van Bussel, G.J.W. (author)The primary objective of the MEXICO (Model Experiments in Controlled Conditions) project was to generate experimental data for validation of models for wind turbines. Kulite©pressure sensors were used for pressure measurements while Particle Image Velocimetry was used with the aim of tracking the tip vortex trajectory. The pressure measurements...conference paper 2010

Akay, B. (author), Ferreira, C.S. (author), Van Bussel, G.J.W. (author)Several methods from experimental to analytical are used to investigate the aerodynamics of a horizontal axis wind turbine. To understand 3D and rotational effects at the root region of a wind turbine blade, correct modeling of the flow field is essential. Aerodynamic models need to be validated by accurate experimental data. In this paper, the...conference paper 2010

Ferreira, C. (author), Hofemann, C. (author), Dixon, K. (author), Van Kuik, G.A.M. (author), Van Bussel, G.J.W. (author)The Vertical Axis Wind Turbine, in its 2D form, is characterized by a complex unsteady aerodynamic flow, including dynamic stall and blade vortex interaction. Adding to this complexity, the 3D flow causes spanwise effects and the presence of trailing vorticity and tip vortices. The objective of the current paper is to bring insight into the 3D...conference paper 2010

Geurts, B.M. (author), Simao Ferreira, C. (author), Van Bussel, G.J.W. (author)Wind energy in the urban environment faces complex and often unfavorable wind conditions. High turbulence, lower average wind velocities and rapid changes in the wind direction are common phenomena in the complex built environments. A possible way to improve the cost-efficiency of urban wind turbines is the application of flowenhancing...conference paper 2010

(author)One of the results of the development of wind energy conversion solutions for the built environment is the reappearance of Vertical Axis Wind Turbines (VAWTs). The application of wind turbines in urban environments presents design challenges driven by the complex wind fields experienced in the urban boundary layer. Urban Wind Turbines operate...conference paper 2009
