| Abstract: | We propose a numerical scheme which aims at solving shape optimization problems in the context of hydrodynamic stability. It is the goal to minimize the drag and ensure hydrodynamic stability by modification of parts of the underlying geometry. The stability issues are represented by eigenvalue constraints. Numerical results for a test case show that a transition from an unstable design into a stable one is attainable by considering an adequate change of the geometry. (© 2008 WILEY-VCH Verlag GmbH & Co.
