Well -what I am getting at is the point of the discussion.
Maybe I don't know all there is to know about fluid dynamics -however it is enough knowledge to invent workable ,proven money making patents involving fluid flow and heat control.
Almost all the Leisure suits made by Levi Strauss in the 60's-were thermal set on the machines I designed and patented.
So much for my credentials.
Those and a buck will maybe get you a cup of coffee today
The discussion is about how does the cooling on model engine really work-
Not analogies- nor who's ---- is the biggest .
My comments on cooling -in models- is from only one viewpoint - actual, measured cooling on many different engine/cowl setups.
And I made some pretty good screwups along the way .
Still do -
Cooling the engines -is like moving a chain down a road - you can't push it along - put it will pull very nicely.
