Optimization of aeroelastic flapping motion of thin airfoils in a biplane configuration for maximum thrust
Kaya, Mustafa; Tuncer, İsmail Hakkı; Jones, Kevin D.; Platzer, Max F. (2007-01-01)
An aeroelastic flapping motion of thin airfoils in a biplane configuration is optimized for maximum thrust. Airfoils are attached to swing arms by an elastic joint, which is model led by a torsional spring. A spring-mass system is employed for the aeroelastic coupling. The stiffness coefficient and the mass moment of inertia of the airfoil are optimized for maximum thrust. A gradient based optimization method is employed in a parallel computing environment. Unsteady, low speed flows are computed in parallel...

© 2015, American Institute of Aeronautics and Astronautics Inc, AIAA. All rights reserved.Mesh deformation technique plays an important role in several numerical simulations and applications including design optimization. This paper aims to implement the developed unstructured mesh deformation technique for CFD Design Optimization around 2-D Airfoils. During the optimization procedure, the newly deformed mesh is generated by using the updated Ball-Center Spring analogy mesh deformation technique. The compar...

Flow measurement in open channels by combined use of free surface PİV and CFD
Gharahjeh, Siamak; Aydın, İsmail; Department of Civil Engineering (2016)
Stream discharge measurement in open channels is of great importance in hydraulic engineering. For many years, classical devices such as propellers, current meters and weirs have been used for this purpose. In recent times, non-intrusive methods such as PIV (Particle Image Velocimetry) and PTV (Particle Tracking Velocimetry) have been very popular as they are more practical and convenient to automatically collect water free surface velocity which is further analyzed for discharge measurement. Image processi...
