Dyson Air Multiplier

Introduce to you a new technology and new product..if you not already knew..

Its fantastic and amusing..
Dyson Air Multiplier, a fan, 风扇, kipas.

What so amusing about it?
because it is a fan with no blades, no buffeting.


so how does it work?

Instead the air is driven up into the ring-shape you can see in the picture. The jet of air created passes over an airfoil ramp that channels its direction. Added to this is the fact that the surrounding air is drawn into this flow of air, combining to amplify the flow of air by a factor of 15. The Dyson fluid dynamic engineers call this process of amplification 'inducement and entrainment' - something they know well in relation to the Air Multiplier, as they ran hundreds of simulations to map the air flow
