Cooling tower shape
Cooling tower shape
(OP)
I was wondering why cooling towers are shaped hyperbolically. I was guessing that it decreases the pressure and increases the velocity of the exhaust air right above the fan, acting as a better vacuum. But, why is it flared at the ends again at the top?

Natural draft is produced on basis of the buoyancy of warmer and more humid rising air. IMO the adoption of the hyperboloid shape was entirely was based on economics: minimum use of material of construction and enhanced structural strength. Comments are gladly invited.
