To build the generator we used ordinary rainwater tank, in which previously cut out the inlet. The next step was the use of denim as a membrane which was attached to the back of the container. Its tension allows the rubbers connected to the container through hooks which reduce their fraying.
So how our generator works in generally? By stretching the membrane attached to the wider end of the container we cause suction portion of air into tank interior. Then when release the handle the diaphragm returns to its former position while pushing the compressed air through the reduced tank outlet, which further increases its speed. On the outside of the tank compressed air is decelerated and pushed aside by the atmospheric air located in its path. Moving forward core again entrained air outwardly bent to form a ring. To accurately visualize the phenomenon occurring before any movement of the membrane outlet of the tank fill with smoke using generator, which can be found in every decent disco.
Where in practice we meet with such a phenomenon? Such vortices are formed spontaneously in nature which is associated with common convection currents, which may take the shape of a ring. You may encounter this phenomenon while volcanic eruptions, as well as under water. Ring vortex generators are also used to break up the cloud hail (of course they have more power).
