Micallef, D. (author), Akay, B. (author), Sant, T. (author), Simao Ferreira, C.J. (author), Van Bussel, G.J.W. (author)The scope of this work was to investigate radial flow component for a Horizontal Axis Wind Turbine in axial flow conditions and to assess its impact on the turbine operation. This was done by means of Particle Image Velocimetry and numerical simulation with a 3D unsteady potential-flow panel model. A direct comparison between the numerical and...conference paper 2011

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

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
