Bladeless fan works differently from conventional fans. The upper part of the fan is the ring, The lower part of the fan is cylindrical and has a variable speed control switch on it.
The bladeless ring works in a manner similar to aircraft wings. Actually, the fan does have blades; They are provided in the base of the fan. The air comes in towards a circular structure called a mixed flow impeller inside the cylindrical structure. The mixed flow impeller is actually an air pump, and it is used for blowing air upwards to the ring.
When the air reaches the ring, it creates a negative pressure above the joint of the ring and cylinder. This negative pressure forces the air that is present over the back side of the ring forward. Further, this creates a negative pressure at the back side of the ring, and due to this, air starts flowing from back to front, in what is called the Coanda effect. The air flows forward in a circular cross section. The air around the flow also starts moving due to viscous shearing, and the speed of the flow becomes sixteen times larger than that of any ordinary fan
