I'd be wary of tripping the flow and perhaps modifying the way the duct handles the flow with any strings.  Besides, how would you observe it--fly in close formation?  Sounds fun, but...
   
  I've never tried it, but I've heard that smearing oil (old, dirty stuff will probably show up better) on an area of interest will clearly show not only the direction, but also the stability of the flow--laminar/turbulence boundary--on the surface.  EZ guys use this when toying with the numerous cowl designs that abound for Rutan canards.  They dab it on upstream, go flying and then see where the oil went after landing and shutting down (and of course, wipe off the mess).
   
   Cheers,

  Is there yarn small enough, yet big enough to see, that could tell us the flow of water droplets about a teeny NACA?  I have further questions, but my wife wants to go to dinner.  Tata for now..
