What happens when you add a vortex generator (not trip strip) to a high lift or laminar wing, operating say at 500k to 1,000k Re?
I understand vortex generators add a little less lift than a slat on a classic naca wing, about 0.6cL. I understand that vortex generators are very different than trip strips, as they actually add energy to the boundary layer. I understand that both vortex generators and trip strips change the flow from laminar to turbulent, but trip strips don't add cl like a vortex generator does.
So ... what happens when you add a vg to a high lift wing like the selig 1233 or the eppler or Wortmann series of reflex or non-reflex laminar wings.
Do vortex generators still add about 0.6Cl or is it actually detrimental as these wings are designed to operate in laminar flow, not turbulent flow?
