Experimental and numerical investigation of flow field around flapping airfoils making figure-of-eight in hover Başkan, Özge; Alemdaroğlu, Hüseyin Nafiz; Department of Aerospace Engineering (2009) The aim of this study is to investigate the flow field around a flapping airfoil making figure-of-eight motion in hover and to compare these results with those of linear flapping motion. Aerodynamic characteristics of these two-dimensional flapping motions are analyzed in incompressible, laminar flow at very low Reynolds numbers regime using both the numerical (Computational Fluid Dynamics, CFD) and the experimental (Particle Image Velocimetry, PIV) tools. Numerical analyses are performed to investigate the...
Measurement of leading and trailing edge vortex shedding mechanism for flapping airfoil in hover using particle image velocimetry technique Çekinmez, Aybüge; Alemdaroğlu, Hüseyin Nafiz; Department of Aerospace Engineering (2013) In this thesis, the vortex shedding formation/mechanism for flapping airfoil making the figure of eight motion in hover is investigated experimentally using Particle Image Velocimetry (PIV) technique and numerically for some parameters determined. For this investigation, a new flapping mechanism is designed and implemented to the existing water tank, where the airfoil is traversed laterally, such that the motion depicts a figure of eight. The traversing system is moved both in x (horizontal) and y (vertical...
Low reynolds number aerodynamics of flapping airfoils in hover and forward flight Günaydınoğlu, Erkan; Kurtuluş, Dilek Funda; Department of Aerospace Engineering (2010) The scope of the thesis is to numerically investigate the aerodynamics of flapping airfoils in hover and forward flight. The flowfields around flapping airfoils are computed by solving the governing equations on moving and/or deforming grids. The effects of Reynolds number, reduced frequency and airfoil geometry on unsteady aerodynamics of flapping airfoils undergoing pure plunge and combined pitch-plunge motions in forward flight are investigated. It is observed that dynamic stall of the airfoil is the mai...
Numerical and experimental investigation of pitching / plunging airfoils in hover Hızlı, Hasan; Kurtuluş, Dilek Funda; Department of Aerospace Engineering (2012) In this thesis, results of the numerical and experimental study corresponding to four airfoils, namely SD7003, NACA0012, 10% thick elliptical, 10% thick flat plate, undergoing sinusoidal pure pitch, pure plunge and combined pitch-plunge types of hovering motion are presented. A number of cases are investigated consisting of different pitching and plunging amplitudes. The study aims to provide a better understanding of the aerodynamics phenomena and the vortex topology of flapping wings in motion for applica...
Parallel, navier-stokes computation of the flowfield of a hovering helicopter rotor Geçgel, Murat; Özyörük, Yusuf; Department of Aerospace Engineering (2003) The aim of this study is to extend a parallel Fortran90 code to compute three6dimensional laminar and turbulent flowfields over rotary wing configurations. The code employs finite volume discretization and the compact, four step Runge-Kutta type time integration technique to solve unsteady, thin6layer Navier6Stokes equations. Zero6order Baldwin6Lomax turbulence model is utilized to model the turbulence for the computation of turbulent flowfields. A fine, viscous, H type structured grid is employed in the co...
