Does re-attached flow negate prior drag ?
Dumb question of the week : Does re-attaching flow negate drag prior to the cause of the drag ?
Example : Darin's Insight and Civic boattail designs with open tail lights.
There is turbulence just after the tail lights, but it reataaches farther on.
I would think that of coarse it doesn't - it just smooths the flow later on, so that the air does not continue to produce even more drag.
Duh.
