Aerodynamic shape optimization by variable-fidelity computational fluid dynamics models: a review of recent progress
Abstract
A brief review of some recent variable-fidelity aerodynamic shape optimization methods is presented.We discuss three techniques that—by exploiting information embedded in low-fidelity computationalfluid dynamics (CFD) models—are able to yield a satisfactory design at a low computational cost, usu-ally corresponding to a few evaluations of the original, high-fidelity CFD model to be optimized. Thespecific techniques considered here include multi-level design optimization, space mapping, and shape-preserving response prediction. All of them use the same prediction–correction scheme, however, theydiffer in the way the low-fidelity model information it utilized to construct the surrogate model. Thepresented techniques are illustrated using three specific cases of transonic airfoil design involving liftmaximization and drag minimization.
