I have been thinking about how I want to try and flow the air through my
Sam James "Rotary Cowling" and I am wondering what you all thought about the
possibility of creating some "bypass" air to help accelerate the airflow
out of the engine before it re-enters the airflow along the belly of the
aircraft.
I also was wondering if there might be some advantage during ground
operations and climb out if I install some kind of door as seen in the
diagram...

Doug,
Hot air rises - that's for sure! but from my knowledge that's a high
pressure area and would more than likely push air into the cowl.
As far as air by-pass, I've not heard of that before, it sounds like it
might create pressure at the back of the radiator restricting flow through the
radiator; unless it was an exhaust augmenter which creates a low pressure area
and sucks on the radiator exit. This has been done successfully by many.
