Aerodynamic shape optimization using adaptive remeshing
Adaptive mesh refinement is one of the most important tools in Computational Fluid Dynamics (CFD) for solving complex engineering design problems. The paper investigates two practical transonic aerofoil design optimization problems using a genetic algorithm coupled with an Euler aerodynamic analysis tool.

Aerodynamic shape optimization of fan blades
The purpose of this work is to develop and evaluate an inverse optimization algorithm which designs two-dimensional fan blade shapes. Given a prescribed pressure distribution and inlet and outlet flow angles, this design optimization technique finds the optimal fan blade shape, stagger angle, and pitch/chord ratio.

Massively parallel aerodynamic shape optimization
Computing Systems in Engineering, 1992Abstract We consider the problem of finding the shape of an airfoil which produces a pressure distribution closest to a desired one. The flow is modeled by the nonlinear potential equations of compressible flow. The problem is formulated as an optimization problem constrained by a discrete approximation to a nonlinear boundary value problem.

Effect of Shape Parameterization on Aerodynamic Shape Optimization
45th AIAA Aerospace Sciences Meeting and Exhibit, 2007This paper studies the effect of shape parameterization on automatic aerodynamic shape optimization. Four shape parameterization techniques are studied: mesh points, Hicks-Henne bump functions, B-spline curves and the PARSEC method. The objective is to compare them based on accuracy and impact on the computational cost.

Aerodynamic shape optimization of turbomachinery cascades
13th Computational Fluid Dynamics Conference, 1997During the last years, steadily increasing interest in computer based methods for aerodynamic shape optimization can be observed. The approaches that emerged up to now can be divided mainly into two groups methods based on genetic algorithms and numerical optimization methods.
