Lets NB that an electron traveling at around 175 000km/h (IIRC) does not stop until it's inside the 2nd surface.
Any air molecule that may have been ionized by said electrons may well be traveling a lot slower, but also does not stop until IT is the molecule on the opposite charged surface.
ie: Airspeed is of little importance here and Boundary Layer is no longer part of the equation!
For anyone else who doesn't give a buck afout Renaults or his nucking fumber after seeing that,
See B here for how you do DBD:

Here are all the high voltage doodats you might require:

1) Pick a useful 'size' for your wing.
2) From it's 'length', reverse-engineer it's required velocity in standard air, based upon the given stated Rn.
3) Then explain to the global community how they could derive any possible benefit in the 'real world ' from the 'so-called' technology, when applied to automobiles operating at common posted speed limits.
( the big clue is, the difference between a laminar, and turbulent boundary layer )
