Computational Algorithms for High-Fidelity Multidisciplinary Design of Complex Aerospace Systems

Abstract

During the first year, with the help of S. Nadarajah, a number of different studies on the suitability of the continuous and discrete adjoint formulations for design using the viscous Reynolds-Averaged Navier-Stokes equations were carried out. Our conclusion is that the implementation of the continuous formulation is more straightforward and leaves more freedom on the choices of discretization of the adjoint equations. We found, however, that the discrete adjoint approach can be very helpful in resolving some of the mathematical ambiguities that are left in the continuous approach when creating imposing boundary conditions.
