Abstract

Far-field analysis for drag prediction and decomposition is here explored and applied to aerodynamic shape design problems. The work aims at illustrating how the far-field approach may allow substantial reductions of the computational effort required by a shape design task. The advantage of this method, in comparison with classical near-field methods, is illustrated both in the classical field of deterministic design optimization and in the robust shape design context. In particular, the approach is shown by optimizing the wave drag of a NACA 0012 airfoil in transonic flow conditions at zero angle of attack. Both the deterministic and the robust stochastic approach have been used, and the obtained results are here reported.
