Aerodynamic Shape Optimization with Grassmannian Shape Parameterization Method
Energies, 2022 The conventional method of optimizing the aerodynamic performance of an airfoil heavily depends on the confines of the design space. The design variables create a non-normalized space that is fragmented into several different clusters of airfoils.

Multiphase Shape Optimization Problems [PDF]
SIAM Journal on Control and Optimization, 2014 This paper is devoted to the analysis of multiphase shape optimization problems, which can formally be written as $\min\Big\{{g}(F_1( _1),\dots,F_h( _h))+ m\vert\,\bigcup_{i=1}^h _i\vert :\ _i\subset D,\ _i\cap _j =\emptyset\Big\},$ where $D\subset\mathcal{R}^d$ is a given bounded open set, $\vert _i\vert$ is the Lebesgue measure of $ _i ...
