Integrated optimization method for airfoil aerodynamic characteristics

To reduce the numerical simulation amount and improve the optimization efficiency for automotive airfoil aerodynamic characteristics, a experiment matrix is obtained by Isight and Latin Hypercube sample and the numerical simulation is performed. An approximate model is built based on the simulation results and the global optimization is performed by evolutionary algorithm. The results indicate that, the integrated optimization method can get reasonable airfoil installation parameters; it only depends on the optimization process of the approximate model and can quickly obtain the rational results according to different constraint conditions and optimization goals; the optimization cycle is dramatically shortened.
