Abstract. For a generalized Brinkman-Forchheimer’s equation under divergence-free and mixed boundary conditions, the stationary equilibrium problem and the inverse problem of shape optimal control are considered. For a convex, geometry-dependent objective function, the equilibrium-constrained optimization is treated with the help of an adjoint state within the Lagrange approach. The shape differentiability of a Lagrangian with respect to linearized shape perturbations is derived in the analytic form by the velocity method. A Hadamard representation of the shape derivative using boundary integrals is derived. Its applications to path-independent integrals and to the gradient descent method are illustrated.
