Abstract
The industrial design of turbines and compressors requires fast and reliable algorithms for the numerical optimization of design parameters that influence the flow in the turbomachine. The engineering process of designing the shape of the blades inside the turbomachine aims at the matching of the velocity profile of the flow around the blade with desired properties. This problem is formulated as a boundary control least squares minimization problem. A new direct simultaneous solution approach is developed which uses at its core a partially reduced SQP-method allowing for intermediate infeasibilities. Special multigrid methods are constructed for the solution of the arising large scale forward and adjoint linear systems.
