Exhibit 1: Wind Tunnel
Plasma Actuators for Flow Control
Plasma actuators are used for flow control applications in the near-wall region. They consist of two electrodes separated by a nonconducting layer and can easily be applied on arbitrary surfaces. If the electrodes are powered with a high-voltage, a strong electric field is created. This leads to ionization of surrounding air molecules and a weakly charged plasma spreads along the surface. The ionized air molecules collide with neutral ones which are subsequently accelerated.
The resulting force is used for separation control on airfoils as can be seen in the exposition.
This challenging flow-control method is descriptive demonstrated in our exhibition experiment.
Exhibit 2: Surface Cube
To get an impression of a variation of smart interfaces a surface cube with 6 different surfaces is displayed at the Hannover Messe. Structures like the lotus effect, plasma or sinus curves can be experienced visually and haptically.
