Electromagnetic control of separated flows using periodic excitation with different wave forms


Electromagnetic control of separated flows using periodic excitation with different wave forms

Cierpka, C.; Weier, T.; Gerbeth, G.

Time periodic Lorentz forces have been used to influence the separated flow on an inclined flat plate in deep stall at a Reynolds number of 10000. The influence of the control parameters effective momentum coefficient and excitation frequency as well as excitation wave form is discussed based on phase averaged PIV measurements. As expected, control authority depends strongly on momentum input and excitation frequency, but effects of the excitation wave form can be shown as well.
