Aerodynamic optimization of turbomachinery cascades using Euler/boundary-layer coupled genetic algorithms
Oksuz, O; Akmandor, IS; Kavsaoglu, MS (American Institute of Aeronautics and Astronautics (AIAA), 2002-05-01)
A new methodology is developed to find the optimal aerodynamic performance of a turbine cascade. A boundary-layer coupled Euler algorithm and a genetic algorithm are linked within an automated optimization loop. The multiparameter objective function is based on the blade loading. For a given inlet Mach number and baseline cascade geometry, the flow inlet and exit angles, the blade thickness and the solidity are optimized by a robust genetic algorithm. First, the Sanz subcritical turbine cascade is selected ...
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...
Aerodynamic modelling and optimization of morphing wings
Körpe, Durmuş Sinan; Özgen, Serkan; Department of Aerospace Engineering (2014)
This thesis deals with aerodynamic optimization of morphing wings under performance and geometric constraints. In order to perform the optimization process, flow solvers computing aerodynamic lift and drag were developed as a function evaluator. A gradient based optimization method was used in order to develop the optimization algorithm. Three dimensional panel method solver was developed in order to obtain lift, pressure drag and induced drag values for a finite wing. Obtained results were compared with di...
