actually is the same whether it is tissue or beer cans.

Sigh my ass. The reason there is a Wind Chill factor is the wind will
carry away the extra BTU's that still air can not. The body's response
is that it tries to get to the ambient temperature faster. At the same
speed as if the air was xx degrees colder. The Wind Chill factor. Same
reason that RCE stated that turbulent flow will transfer more heat.
Laminar flow will have a small slow speed component of air right next to
the surface. That small bit of air will insulate the surface from the air
above. Works with beer cans also. Same reason that a car radiator works
with air flowing over it. No fan and hot day and sitting still and you
overheat.
I agree with everything you posted, including tissue or beer cans, except
the effect is not "wind chill". In moving air the tissue and beer can, if
warmer or colder than the ambient temperature will cool or warm faster to
the ambient temperature than in still air.
Wind chill is the apparent lower temperature (than ambient) that living
tissue experiences due to it's inability to keep up with the increased heat
loss in windy conditions. It is equal to that temperature the tissue would
be exposed to if there was no wind.
And with that, I am done with this wind chill discussion. It's leaving me
cold.
Well, I'm glad to see everybody having fun today. :)
