Fellow techo's

Has anyone given thought to the turbulence that the butterfly valve introduces to airflow and what possible altenatives could be designed?

Take a bottle of water, turn it upside down–see how fast it empties-glug, glug. Same bottle of water, instill in it a rotation by circular motion, turn it upside down and vortex will assist emptying.

Case study: 750 ml Wolf Blass Eaglehawk wine bottle.
Straight (glug) empty: 9.29 seconds
Vortex empty: 4.76 seconds
n=1

Liquid=water (just drank the wine Wink

Any thoughts?

David
