摘要
The inverse aerodynamic design of transonic airfoil shapes using parallel simulated annealing (PSA) and computational fluid dynamics (CFD) was discussed. The objective function was evaluated using the flow analysis module, based on the finite volume method of Navier-Stokes equations. The PSA was implemented by dividing the Markov main chain into subchains on multiple processors. Results showed that the airfoil shape is parameterized using 14 basis functions, in which 7 define the upper surface and the other 7 define the lower surface of the airfoil.
