Aerodynamic Shape Optimization Methods
1997Although fast and accurate in creating aerodynamic shapes compatible with the specified surface pressure distribution, the inverse shape design methods create configurations that are not optimal even at the design operating conditions [163], [164].

Aerodynamic Shape Optimization of Heat Exchangers
2023The development of efficient methods to reject waste heat has been instrumental throughout aircraft design history. In current airliners heat exchangers cool the cabin air, avionics, and engine oil. As the aviation industry transitions toward electric or hydrogen-powered propulsion, heat exchangers will become more important.

Aerodynamic Shape Optimization by Space Mapping
2013This chapter describes an efficient aerodynamic design optimization methodology for wings in transonic flow. The approach replaces a computationally expensive high-fidelity computational fluid dynamic model (CFD) in an iterative optimization process with a corrected polynomial approximation model constructed by a cheap low-fidelity CFD model.

A Framework for Aerodynamic Shape Optimization
2009A framework for aerodynamic shape optimization is presented. It uses a shape parameterization method based upon the Chebyshev polynomials, an unstructured finite-volume formulation for the solution of the Euler equations and a discrete adjoint method for the computation of the sensitivity.

Aerodynamic Shape Optimization of a Stator
Volume 12C: Turbomachinery — Design Methods and CFD Modeling for Turbomachinery; Ducts, Noise, and Component InteractionsAbstract In this paper, a numerical study conducted on a compressor stator is presented. The results are compared with existing literature and experimental data. For this purpose, a grid refinement study for the baseline geometry at the design condition with an unstructured mesh family is performed.
