✦ Synopsis

a b s t r a c t

In this paper we consider shape optimization of systems, which are governed by external Bernoulli free boundary problems. A pseudo-solid approach for solving discrete free boundary problems is introduced. The solution strategy readily allows us to obtain geometrical sensitivities of the system, in particular the sensitivity of the free boundary. The sensitivity information can then be used to solve, e.g. inverse design problems, where the free boundary is driven towards some target boundary by changing the shape of the other component of the boundary.

Optimal shape design approach is applied to numerical computation of a model potential free boundary value problem. The problem is discretized using the ÿnite element method. To test the approach the problem is formulated in both velocity potential and stream function formulation and four di erent ÿ
