... that I intend to gather first in a terminal of form anal concentric...

It's a sassy configuration! : Cheesy:

ppfiuuu it becomes grivoix unexpectedly, in any case, we all hope that this "anal" form will not lack air : Mrgreen:

Yes Turbinair, I still believe that making an orientation of flows "roughly" in the rules of the art would not cost you much more and does not require a battalion of engineers ...

Try to tilt your air inlets and also work on the blades ... Inspire yourself, Francis or Turgo. You also have engine turbochargers, which are a bit of miniature Francis.

As for Chatelot, it makes you good remarks, me I reason a little on the case of the pressurized fluid, but if it is not under pressure, then it is necessary more to resort to phenomena of lift that of impact, so we would be there more in wind turbines and airplane wing profiles for blades ... or else very rustic vertical axis wind turbines, like Savonius ... but the yield is lower.

Finally it is the whole approach process that has benefited

Finally it is the whole process of approach that has benefited from this blunder! Rationale: I write all at once, and in order not to interrupt this regime, I write the term preserving the basic wording on which I return for the development of the text. In this case, I thought "ringed" (inspired by the geometric figure) while writing "anal" ... unconsciously fearing probably that it does not fart! Is not that that relieves ... laughter!
Thank you Remundo for the proposal regarding the profile that seems to announce the outcome.

if there is no pressure there is no power

power = flow x pressure

if pressure = 0 power = 0

even a wind turbine has a certain pressure, weak but not zero: another way of understanding the limit of betz, it is to seek the optimum pressure to oppose the wind

if pressure too low power too low

if too much pressure the wind passes by the flow becomes too weak and it is not good either

the turbine design must be adapted to the flow source! what pressure can she do?

Being neither a specialist in turbines or breakdowns or flatulence:

anal, everyone understood the meaning

ringed is not the adjective meaning "ring-shaped" - this applies to worms made up of rings

the adjective which means "ring-shaped" is annular (like the finger for that matter).

French is sometimes complicated and sometimes facetious!

Help for complex calculation

Hello everyone,
Here, I developed a diagram with a question that is important to me: can we achieve a flow of 3 or 4 m3 / s with such a turbine? all specifications are in this diagram.
thanks.

If the air flows are parallel to the vanes (as I think from the drawing), why should we see a rotation?

Basically, if instead of telling us about your turbine, you first told us what gave you this hot air, how much, and especially how much pressure.

because, if it drops your huge turbine, may not be the best solution to recover this energy.
