Axial flux generator with novel flat wire for direct-drive wind turbines
Çakal, Gökhan; Keysan, Ozan (2021-01-01)
With the increased demand for renewable energy resources, the direct-drive wind turbine generators have been studied intensely in the last few decades. One megawatt direct-drive axial flux permanent magnet generator is presented. The novelty in this design is that instead of conventional stranded wires, the windings of the generator are manufactured from a conductor sheet by cutting and bending processes. This creates critical advantages of superior current ratings, ease of manufacturing, and reduced struct...
Vortex flow aerodynamics behind a symmetric airfoil at low angles of attack and Reynolds numbers
Kurtuluş, Dilek Funda (2021-11-01)
The low Reynolds number aerodynamics is important to investigate for micro air vehicle applications. The current paper covers numerical simulations to present the downstream development of the wake patterns and detailed analysis of the vortices generated at the downstream of NACA 0012 airfoil around the critical angle of attack where the instantaneous vortex patterns are oscillatory and differ from the mean vortex pattern for low Reynolds numbers ranging from 1000 to 4000. The instantaneous and mean aerodyn...
Vortex generator design for subsonic inlets
Nasuhbeyoğlu, Batuhan; Albayrak, Kahraman; Department of Mechanical Engineering (2014)
In this thesis, numerical investigation of the benefits of vortex generators control on the performance of S-shaped inlets has been performed. This study is divided into two main parts. In the first part, a diffusive S-shaped inlet is examined and the numerical analyses results are compared with the experimental results. Three-dimensional Navier-Stokes equations are solved and three different turbulence models which are Realizable k-ε, Standard k-ω, and Spalart-Allmaras methods are used. Distortion coeffici...
Aerodynamic optimization of horizontal axis wind turbine blades by using CST method, BEM theory and genetic algorithm
Oğuz, Keriman; Sezer Uzol, Nilay; Department of Aerospace Engineering (2019)
In this thesis, an aerodynamic design and optimization study for rotor airfoils and blades of Horizontal Axis Wind Turbines (HAWTs) is performed by using different airfoil representations and genetic algorithm. Two airfoil representations, the Class-Shape Transformation (CST) method and the Parametric Section (PARSEC) method, are used for the airfoil geometry designs. Their aerodynamic data is obtained by a potential flow solver software, XFOIL. The Blade Element Momentum (BEM) theory is used to calculate t...
