| contents | In this work, we study a boundary control problem for the evolutionary Navier-Stokes equations, under mixed boundary conditions, in two dimensions. The cost functional here considered is of quadratic type, depending on both state and control variables. We provide a comprehensive theoretical framework to address the analysis and the derivation of a system of first-order optimality conditions that characterizes the solution of the control problem. We take advantage of an adequate treatment of the Dirichlet control through the study of the reduced functional. Despite the fact that this approach is quite common, a detailed analysis for the case of mixed boundary conditions with is still lacking. Finally, solution-finding algorithms of descent type are proposed and illustrated with several simulations. |
