The combination of the optimization software,modeFRONTIER and the commercial CFD software is used to optimize the aerodynamic functions of the airfoil,NACA0012.The N-S equations are adopted for calculating the airfoil aerodynamic properties(Cl,Cd and etc).Two kinds of optimization algorithm,the Multi-Object Genetic Algorithm(MOGA) and the Multi-Object Simulated Annealing(MOSA),are used in the optimization process respectively.The optimized airfoils show remarkable improvement of its aerodynamic functions(The ratio of lift to drag increases up to 282%) relative to its original one.
