When the air reaches the ring, it creates a negative pressure above the joint 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 tofront, in what is called Coanda effect.
The air flows forwards in a circular cross section.
The air around the ring flow also starts movng due to the viscous hearing, and the speed of the flow becomes fifteen larger than that of any ordinary fan.Compared with the traditional fan, the airflow for the bladeless fan is more stable ,sitting in front of a bladeless fan, you will feel comfortable and cozy.
