I use the term 'wrapping around curved surfaces' (and similar) to explain the low pressures that are generated when attached flow follows a convex surface*.
In an email to me last week, former head of Porsche aerodynamics, Dr Thomas Wolf, puts it this way:
"According to the Coanda-Effect the air follows the curved (upper) surface. According to Newton’s first law, there must be a force which pulls the air downwards. This force is exerted to the air by the car body and pulls the air downwards. According to Newton’s third law (action = reaction) there must be a force of the same magnitude in the opposite direction acting on the body."
But hey, what would Dr Wolf know?
Unfortunately, a lot of what Aerohead so steadfastly believes is simply wrong, as some simple on-car measurements very quickly shows. It's just a crying shame that Aerohead has so effectively mislead so many people here for so long.
(*The opposite happens with concave surfaces - high pressures are developed.)
