Abstract
  To keep pace with current trends in the wind industry, this paper aims at the improvement of the annual energy production of a horizontal axis wind turbine by aerodynamic optimization of blades at the wind conditions of the Manjil site. To achieve this goal, the Riso wind turbine, whose characteristics ...  Read More

Airfoil Shape Optimization with Adaptive Mutation Genetic Algorithm

A. R. Jahangirian; M. Ebrahimi

Volume 11, Issue 1 , June 2017

Abstract
  An efficient method for scattering Genetic Algorithm (GA) individuals in the design space is proposed to accelerate airfoil shape optimization. The method used here is based on the variation of the mutation rate for each gene of the chromosomes by taking feedback from the current population. An adaptive ...  Read More

The Effects of Shape Parameterization on the Efficiency of Evolutionary Design Optimization for Viscous Transonic Airfoils

Ava Shahrokhi; Alireza Jahangirian

Volume 5, Issue 1 , March 2008, , Pages 35-43

Abstract
  The effect of airfoil shape parameterization on optimum design and its influence on the convergence of the evolutionary optimization process is presented. Three popular airfoil parametric methods including PARSEC, Sobieczky and B-Spline (Bezier curve) are studied and their efficiency and results are ...  Read More
