Does anyone have any slight knowlidge of "dynamics of flow"? 
This device has come up thanks to the experimentation of Charles T. McCullogh, described at www.steamup.info It's a "killer replacement" for chimneyfans, in my view. Even this initial crude design, provides more than double the suction provided by traditional chimneyfans. It will easily hold a 4x4 inch paperclipping.
All parts are standard plumbing, and a beachtoy inflator. The inflator moves a lot of air, with only moderate pressure.
The air-inlet pipe must end in between the downward column (to the chimney), and the air outlet. It can even just go into the narrower outlet, as long as a small portion around it connects to the air behind and around the air-inlet blowing pipe.
The air-outlet can not be larger in diameter than the inlet blow-pipe - hence the reduction for the outlet, that make them exactly equal. I don't know what would happen, if the inlet blow-pipe was smaller than the outlet ;-)
I bought all the parts ready made yesterday, and was running the T&inflator suction device in 10 minutes! Some standard plumbing-parts, a snippet of hose, and the rechargeable inflator, everything just off the shelves. Total cost (in Sweden) about USD 30!
I would be grateful for any suggestions for further experimentation, because I know nothing about "dynamics of flow", so I have absolutely no idea in what direction to look / go
