This paper presents a complete 3D optimization of a shrouded fan using the Turb'Opty parameterization software. High order derivatives of the flow variables with respect to shape parameters, produced by Turb'Opty, are post-processed using Taylor series expansions coupled with Non-dominated Sorting Genetic Algorithm 2.
