Active flow control earns growing interest for manufacturers of large transport aircraft
because of the constant need to improve these aircraft in terms of less fuel consumption,
higher efficiency, steep approaches and departures and less weight. Flow control devices
that are based on fluidic actuators, e.g. vortex generator jets (VGJs), have shown a promising
potential to influence separating boundary layers and keep them attached (e.g. Godard &
Stanislas (2006a‐c); Johari. & Rixon (2003); Johnston & Nishi (1990); Mc Manus et al. (1996);
Ortmanns et al. (2008a); Pauley & Eaton (1988); Scholz et al. (2006)). For an efficient operation
such devices need to be optimized regarding their ability to influence the flow. However,
optimization turns out to be very challenging because of the vast parameter space and the
lack of an adequate “figure of merit”. The proposed contribution will discuss the possibility
to assess and optimize such devices by analyzing the velocity fields from stereoscopic PIV
measurements.
