Özet

© 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.
