I am not quite sure I am following "angle of the flow to lengthwise of the trim," could you please reiterate?
  • A ridge parallel to flow would have negligible effect.
  • A ridge athwart the flow would act like a Gurney flap; given enough height, promoting reattachment.
  • A ridge at a 45į angle could trigger a vortex on the lee side.
