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...
Effect of isolator and ground motion characteristics on the performance of seismic-isolated bridges Dicleli, Murat (Wiley, 2006-02-01) This paper presents the effect of isolator and substructure properties as well as the frequency characteristics and intensity of the ground motion on the performance of seismic-isolated bridges (SIBs) and examines some critical design clauses in the AASHTO Guide Specification for Seismic Isolation Design. For this purpose, a parametric study, involving more than 800 non-linear time history analyses of simplified structural models representative of typical SIBs, is conducted. The results from the parametric ...

Effect of wave grouping, spectral shape and exreme waves in a wave train on the stability of rubble mound breakwaters Özbahçeci Öztunalı, Bergüzar; Ergin, Ayşen; Department of Civil Engineering (2004) There are some empirical formulas used in the design of rubble mound breakwaters to find the weight of armour layer stone. The effect of wave grouping and spectral shape could not put into these design formulas since their effects are still under question. The influences of wave groups and spectral shape on the stability of rubble mound breakwaters have been investigated by several researchers up to now. However, results were not conclusive in these researches, where different wave grouping and spectral sha...
