These additional influences are active influences because they imply an unsteady or at least adaptive change of boundary or flow conditions with the help of external energy..Examples given in the lectures are the influence of p

Optimal Control and Other Complex Systems Paradigms in the Context of Turbulent Flows,ple, e.g. a fixed point dynamics, it is necessary to perturb it in order to reconstruct the model. Of course, perturbations are also necessary to control a system. The problem with these perturbations is that they may activate additional variables which are not included in the simple model. Thus, th

Passive Ventilation of Shocks in Steady and Unsteady Internal Flows,y supersonic compressor flow. Alternatively we show the effectiveness of ventilation by very thin slits instead of a cavity covered by a porous blade..Finally we apply the method of ventilation to unsteady internal transonic flow. Experiments and numerical results of the Euler equations for inviscid

Instabilities of Compressible Flows with Internal Heat Addition,choking (Delale, Schnerr and Zierep [1]) with steady or unsteady moving shock waves and instabilities like high frequency pressure oscillations. Self-excitation develops because of the instantaneous interaction of the shock with the phase transition process. Control and handling of these steady and

Another more efficient technique uses sound waves focused by a mirror on a small region of a certain wing area. This results in a stronger localised excitation which reduces laminar flow se
