Whatever transpired between the two of you is none of my business, but if Dr. Wolf actually agreed to the use of 'attached flow', as proper nomenclature, then I cannot abide by that.
' Downwash' yes, 'attached flow' no.
Well, you're on your own.

I have already said how the head of Jaguar aero described flow attached through the action of downwash as 'attached flow', and today I noticed that the Aerodynamics of Road Vehicles (5th edition P 37) does the same. In describing the tuft pattern on the Adler (1930s?) the book says:

On both sides the vortices roll up, pull down the flow coming over the roof, and keep it attached until the lower end of the slant.

So you can either be big enough to admit your mistake and correct it, or you can do as you have always done in the past and just say that you're right and everyone else is wrong.
