I mean clearly you know more than the textbooks or the people who have spent not only their lives but also their pHds on the exceptionally hard core and misunderstood area that is boundary layer physics. If you are correct you surely up for a nobel prize. ( this is a joke as what you are saying contradicts a lot of current fluid mechanics as practiced by some very intelligent profs who could continually slap everyone here around till they admit they know nothing about fluid mech and are in fact idoits. If your insight is correct it would earn a Nobel and billions of dollars but I feel that some intelligent guys at Stanford/MIT/Imperial/Cambridge might just say no)

Friction is important but more of it in this context doesn’t mean there is more heat absorbsion. Continuum mechanics would say that more air flow velocity is,

Agreed without viscosity that there would be no heat transfer but beyond on that to understand what is going on you need a pHd as its exceptionally complex.
