CFD Analysis and Shape Optimization of Airfoils Using Class Shape Transformation and Genetic Algorithm—Part I

This paper presents the parameterization and optimization of two well-known airfoils. The aerodynamic shape investigation includes subsonic (NREL S-821) transonic airfoils (RAE-2822). class transformation is employed for parametrization while genetic algorithm used purposes. absolute scheme process carried out minimization drag coefficient maximization lift to ratio. In-house MATLAB code incorporated with a calculate ratio resulting optimized airfoil. panel method utilized in pressure distribution, coefficient, airfoil shapes validates XFOIL NREL experimental data. Furthermore, CFD analysis conducted both original obtained. present shows that achieved an improvement by 7.4% 15.9% S-821 RAE-2822 airfoil, respectively, technique provides high design desirable stability parameters. These features significantly improve overall performance newly Finally, improved aerodynamics results are reported turbulence modeling phase II, Phase III, VI HAWT blades.
