Engineering relies heavily on mathematical models of real systems. However, physical processes are often highly complex and not entirely understood, so the modeling of the first principles can be challenging, sometimes even impossible. System identification allows for any system, however complex or obscure, to be modeled solely on the basis of measurements.
Active flow control by the use of DBD actuators has been proven to be a promising concept for the delay and even elimination of boundary layer separation. In order to further develop these actuators, the interaction between the plasma and the flow under different operating conditions has to be investigated.
