Kurzbeschreibung (Abstract)
An approach for the efficient simulation and optimization of turbulent
reactive flow problems is presented. A gradient-based optimization strategy is
employed involving a parallelmultigrid solver for the flow and sensitivity equations.
The geometry variation is realized using NURBS surfaces providing a large scale
of possible deformations with a small number of design variables. The sensitivitybased
computation of the gradient of the objective function is systematically
verified by comparisons with finite-difference approximations. The efficiency of the
multigrid method and the parallelization is investigated. The functionality of the
optimization approach is illustrated by results for representative test cases.
