We examine the optimal control of stationary thermally convected uid ows from the theoretical and numerical point of view. We use thermal convection as control mechanism, that is, control is eeected through the temperature on part of the boundary. Control problems are formulated as constrained minimization problem. Existence of optimal control is given and(More)
This paper is concerned with optimal control problems for a Ginzburg-Landau model of superconductivity that is valid for high values of the Ginzburg-Landau parameter and high external fields. The control is of Neumann type. We first show that optimal solutions exist. We then show that Lagrange multipliers may be used to enforce the constraints and derive an(More)
This article presents a reduced order method for simulation and control of uid ows. The major advantage of this method over others such as nite element, nite diierence or spectral method is that it has fewer degrees of freedom. The present methodology's feasibility for ow control is demonstrated on two boundary control problems. The rst one is a velocity(More)
