© 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 comparison to the traditional Spring Analogy mesh deformation technique is made as well. SU2 Open Source flow solver is used for performing the CFD Analysis, where a viscous solver is utilized. The optimization processs is done by using Optimization Solver in Phoenix Model Center. In the optimization, the objective function is to minimize the drag, while keeping the generated lift to be constant.

A multi-fidelity, multi-disciplinary analysis and optimization framework for the design of morphing UAV wings Ciarella, Andrea; Tsotskas, Christos; Hahn, Marco; Werter, Noud P. M.; De Breuker, Roeland; Beaverstock, Chris S.; Friswell, Michael I.; Yang, Yosheph; Özgen, Serkan; Antoniadis, Antonios; Tsoutsanis, Panagiotis; Drikakis, Dimitris (null; 2015-01-01) © 2015 American Institute of Aeronautics and Astronautics Inc, AIAA. All rights reserved.A framework for the design and optimization of a morphing wing is presented. It allows the user to simplify the design process of a morphing UAV wing with a simple and effective interface with the possibility to easily switch between flight phases and morphing concepts. It consists of two main solvers: a high-fidelity CFD module for detailed RANS simulation and a fast low-fidelity module that solves the aeroelastic prob...
Structural dynamics analysis and passive control of wind turbine vibrations with tuned mass damper (TMD) technique Farsadi, Touraj; Kayran, Altan (2016-01-01) © 2016, American Institute of Aeronautics and Astronautics Inc, AIAA. All rights reserved.This paper investigates the use of a passive control device, tuned mass damper (TMD) for the control of vibrations of a simplified wind turbine. In the wind turbine model, tower and blades are modeled with continuous beam structure. Concentrated mass is considered as the nacelle. TMD system is placed at top of tower and attached to the nacelle. The coupled governing equation of motions and associated boundary condition...
Modification of the extended messinger model for mixed phase icing and industrial applications with TAICE Ayan, Erdem; Özgen, Serkan (2017-01-01) © 2017, American Institute of Aeronautics and Astronautics Inc, AIAA. All rights reserved.Computational studies have been performed in order to predict mixed phase ice accretion on aircraft components. In-house developed TAICE tool has been used in this study. Previously, TAICE was already validated for icing cases due to water droplets only. In addition, in the framework of High Altitude Ice Crystals (HAIC) FP7 European project, mixed phase ice accretion prediction capability has been added to TAICE. Up to...
Experimental design and statistical modeling methodology for wind tunnel aerodynamics of an agile missile to improve the simulation accuracy and performance Savas, Ozgun; Topbas, Eren; Unal, Kenan; Karaca, H. Deniz; Kutay, Ali Türker (2018-01-01) © 2018, American Institute of Aeronautics and Astronautics Inc, AIAA. All rights reserved.Wind tunnel testing is an essential procedure to investigate the aerodynamics forces and moments. In this paper, a methodology is presented to perform such test in an efficient way. Experimental design process is carried out before the testing in order to cover the flight regime as much as possible with the least possible number of tests. After the determination of the test matrix and conducting the wind-on tests, the ...
Analysis of effects of different diffusion models in hypersonic flow regimes Gur, H. Berk; Eyi, Sinan (2017-01-01) © 2017, American Institute of Aeronautics and Astronautics Inc, AIAA. All rights reserved.Hypersonic flows become popular due to its use in space explorations and military applications. It occurs normally, when a space craft re-enter to the atmosphere. Space crafts are exposed to high temperatures and high pressures because of Earth’s atmosphere and gravity. In addition in high temperatures, gases tend to react with each other. These reactions also have effects on space craft’s surface. In order to calculat...
