This paper outlines the similarities and di erences between the wake characteristics of a porous disc and model wind turbine under transverse gust loading which is generated via a two-vane wind tunnel gust generator. Phase-locked two dimensional two-component (2D2C) particle image velocimetry (PIV) measurements show that the capability of a porous disc in representing a wind turbine increases under gust loading. Compared to the uniform inflow case, normalized streamwise velocity plots of the porous disc and model turbine are in a better agreement under gusty inflow condition particularly in the near wake region. Comparison of the wake centerlines reveals a similar wavy wake pattern with no significant phase lag suggesting that the gust dynamics is the dominant factor in the determination of the wake dynamics.

DETERMINATION OF WAKE SHAPES BEHIND A WIND TURBINE THROUGH CFD SIMULATIONS AND COMPARISON WITH ANALYTICAL WAKE MODELS Adam, Ali Ata; Sezer Uzol, Nilay; Uzol, Oğuz (2021-09-10) In this paper, wake shapes of wind turbine rotors are investigated by using CFD and analytical wake models. The flow around the NTNU model turbine is simulated using the Reynolds-Averaged Navier-Stokes Equations with Spalart-Allmaras, standard k-epsilon, standard k-omega, and k-omega SST turbulence models, k-kL-omega and Transition SST transition models and also with two different freestream turbulence intensities as low and high values of 0.23% and 10%, respectively. The simulations are done for a single t...
Determination of the bending twisting coupling potential of composite materials via digital image correlation and its implementation in wind turbine blades Şener, Özgün; Kayran, Altan; Department of Aerospace Engineering (2017) In this thesis study, the main objective is to investigate the effect of bending-twisting coupling in composite wind turbine blades on the load alleviation, power generation and structural performance of the wind turbine system. For this purpose, experimental and numerical study is initially conducted to determine the bend-twist coupling potentials of composite materials. Bending-twisting behavior of composite materials are determined through a comparative study via the Digital Image Correlation (DIC) syste...
Effect of steady and transient wind shear on the wake structure and performance of a horizontal axis wind turbine rotor SEZER UZOL, NİLAY; Uzol, Oğuz (2013-01-01) This paper presents an investigation of the effect of steady and transient free-stream wind shear on the wake structure and performance characteristics of a horizontal axis wind turbine rotor. A new three-dimensional unsteady vortex-panel method potential flow solver based on a free-vortex wake methodology, AeroSIM+, is used for this purpose. The code is validated using the experimental data from the National Renewable Energy Laboratory Unsteady Aerodynamics Experiments. The effects of vortex core model, co...
Effect of steady and transient wind shear on the wake structure and performance of a horizontal axis wind turbine rotor Sezer Uzol, Nilay; Uzol, Oğuz (2009-12-01) This paper presents an investigation of the effect of steady and transient freestream wind shear on the wake structure and performance characteristics of a horizontal axis wind turbine rotor. A new 3-D unsteady vortex-panel method potential flow solver based on a free-vortex-wake methodology, AeroSIM, is used for this purpose. The code is validated using the experimental data from the NREL UAE experiments, as well as checked against the theoretical models developed by previous researchers. Three-different i...
Design and optimization of high torque density generator for direct drive wind turbine applications Zeinali, Reza; Ertan, Hulusi Bülent; Department of Electrical and Electronics Engineering (2016) In this thesis, it is aimed to design a high torque density generator for a variable speed, direct drive wind turbine application. Such a generator may reduce the size of the turbine tower and the nacelle and may provide cost advantage. For this purpose, various topologies of the permanent magnet machines in the literature are reviewed. Among the reviewed electrical machines, a magnetically geared machine introduced as a concept with high torque density and high power factor is chosen to be evaluated for th...
