Hey Rob, I couldn't find my last post so I tried reposting it (sorry for the complication).
Anyway, I'll have a look at all three of those cited to implement them.
As you've asked on the other post, I want to excite the jet in the range of 10-200 Hz. The Model is really really simple as in the image im uploading below
It consists of a velocity profile coming out generated by an other internal flow simulation.
(Out of the article "Control of a Plane Jet by Fluidic Wall Pulsing" By J. C. Béra, Et al)
I'll post as soon as possible as a reply to this post the contours of velocity & velocity vectors. You've previously asked if I was running transient, and actually I'm initially trying to run steady, and eventually progressing to transient. Also, I'll have a look for fluidic switches as you had said.
