WATER PHENOMENA What is the water, and how water behaves naturally. One can increase the understanding of water by visible movement. We have developed a number of water phenomenon for large and small to experiment with. We design and build even site-specific water phenomena of various kinds. These phenomena stands are designed for major theme parks. Virbela studio also holds courses where water phenomenon is described and illustrated.






The vortex funnel (above) the viewer can study the shape of a water vortex, and discover that it really is a vortex of air in water. By varying the circulation flow, one can see that the faster the circulation of various layers of clear water at the side of the air funnel. These layers screws down along the pipe towards the bottom, resembling a narrow string in the tube below the container. The currents are not straight as one could expect. Around the air string you see particles that spins horizontally around the air string that goes up.



 

Here (above) the viewer can discover what the vessels as the significance of how easily water flows. In the square container with corners everywhere, it is impossible to form a vortex. The cylinder with a flat bottom is easier. The cylinder with round bottom is easiest.


 

     Archimedes was famous for coming up with such no one else thought of before. It was like 2200 years ago and maybe someone tired of carrying water and asked him to come up with something clever. He invented anyway this water screw as Leonardo da Vinci later developed into the propeller. Here (above) we have created a 3-channel screw at the optimum angle of 30 º can lift a lot of water in a steady stream with very little effort on the crank.

 

Rocking bowl (above) is an invention made by designers from Flow Design Research. The challenge for those rocking the dish is to get to a beautiful rocking of the water. Is it right sway creates a harmonious flowing in and out of the rotation of the water. You swing too fast, it will be only chaos.
     

 

What happens when you drag a brush through the water in a straight line? Curiously Every trace of alternating vortices. These are known as vortex streets and occurs everywhere in the air and water, but almost never seen. On vortex gate table, however, these vortices visible thanks to silver colored water is thickened with glycerin.


 


Why winding river? Meander known phenomenon in nature. The reason lies in the interaction between the water's movement patterns and the surrounding landscape character. What happens when you drop water on the polished surface? It meanders anyway! At the end of the disc sees "Coanda" effect, where water persists in the backward curved plate.

 

The inventor Leonardo Da Vinci liked to play, observe and draw water flowing in gutters. How did wake? How moving water under the surface for different items? The "Da Vinci" table viewer can play by adjusting the slope and see what happens in and on the water, thanks to a dye in the water. An electric pump circulates water
