The Coanda effect occurs due to the presence of a curved surface immersed in a flowing fluid when the surface curves away from the flow. The flow 1) causes a lowered pressure at the surface and 2) entrains fluid to flow towards the surface. The effect can be seen as smoke streams in a wind tunnel follow the shape of, e.g. a streamlined automobile.
Another example is a water flow adhering to the back of a spoon. This is caused primarily by the Van der Waals (surface tension) forces between the water and the surface of the spoon.
The Coanda effect was named after the Russian aerodynamics pioneer Henry Coanda. The effect is the tendency of of a fluid jet to be attracted to a nearby surface.
He was born in Bucharest, Romania
he didn't. He just lied about it years after othewrs invented the jet. I, Sorin Ligureanu am ashamed that coanda was such a worthless liar.

The first jet plane was build 1910 by Henry Coanda, a Romanian engineer. 1910, at the International Aeronautic Salon in Paris 1910 he was flying his "Coanda-1910", a "thermojet" powered aircraft.
Not henri coanda. He just said many lies with no prouve.
Henri Coanda - http://www.otp-airport.ro/index.php
Henri Marie Coandă (Romanian pronunciation: [ɑ̃ˈri maˈri ˈko̯andə]; June 7, 1886 - November 25, 1972) was a Romanian inventor, aerodynamics pioneer and builder of the world's first jet powered aircraft, the Coanda-1910. He also discovered the Coandă effect. (wikipedia)
They are blown venturi tubes. A small volume of high pressure air is blown over the curved "wing" of the Dyson ring. This air adheres to the ring via the Coanda Effect and transfers momentum to the air in the ring, creating a high volume of low pressure air.

A Romanian, Henri Coanda, developed an engine in 1910 that was similar to the modern jet engine. Coanda's engine required an external motor in addition to the jet engine so most people accept that his development is not classed as the jet engine that was later developed by Sir Frank Whittle in Britain. Whittle produced the first jet engine that was self supporting and ran without the aid of external equipment.
