Optimization of Axial Flow Compressor Blades Using Genetic Algorithm and Computational Fluid Dynamics

Optimization of airfoil blade section using evolutionary algorithm coupled with numerical methods of analysis is becoming a trend nowadays. A new MATLAB code is developed to realize the optimization of high pressure ratio axial flow compressor blades using genetic algorithm coupled with the Computation Fluid Dynamics (CFD) package. Use of Bezier-PARSEC parameterization is made to parameterize the base CDA airfoil. MATLAB code successfully integrates and runs the optimization process and optimum results thus obtained shows a good agreement with experimental results
