Air vortexes

On a factory floor of Boeing the big aircraft company is supposed to be a saying:

Our engineers have worked out that a bumblebee can´t fly.

It is very nice to hear, how the academics fool themselves. Apparently they feel that there are things between heaven and earth we can´t perceive with our limited sense organs and meters. After zillions of years of developing work it is exactly nature presenting us solutions our technicians only dreamt of. Viktor Schauberger, the ingenious Austrian autodidact polymath, started here and formed the key to his successnote:

First figure it out – then copy it.

Indeed they have seen hurricanes before Katrina which inspired the director Andreas Linke for his TV-film „Tornado – Zorn des Himmels“. What sort of power becomes manifest in such a phenomenon! Perhaps it is possible to domesticate these forces for the use of energy generation. The chapter Vortexes in Technology shows how it is possible to let work the vortexes for us. Up to now to my knowledge there is no device in which an artificial vortex energy is generated. But it would have charm.

So the challenge: to create an artificial tornado!

The Wirbelkammer is such a possibility. I found the model on this website www.tornadoproject.com. In reality it was not so easy for me to built the apparatus. But there is it working properly. Input of energy for the creation of a tornado: approx. 50W.

The next experiments are about stabilizing the tornado, directing towards a self-amplifying process, in a way that the energy input is reduced. You can see it at www.vortex-dynamics.com.au/visual2.html, however it contains a more artistic ambition – the eye-catcher.

Ranque-Hilsch-Vortex-Tube

This tube is a fascinating invention. This is the reason why I have ordered a vortex tube and built up the experimental set-up with two temperature meters and a pressure meter. It is the smallest model available, shown below, and nevertheless it is possible to get -25°C without any problems. What sort of potential is incorporated in this device?

Water Vortexes

Twister

Yet pouring tea into a cup we can see much mysterious force keep the water-jet together. In another chapter I assumed a witch was responsible for this. Perhaps is it really a law of nature, that all fluids begin spiralling at a certain viscosity, at least when they start flowing.

Perhaps a little earlier, once heat equalisation enhances convection processes because of differences in temperature. There is an impressive story by Theodor Fontane in his novel „Der Stechlin“.

Under certain weather conditions floating branches and whole trees on a lake are forced to the centre and sucked down. After a fairly long time the lake spits all the lumber and timber with thunderous boom from the depth of the water and throws it into the air.

My first goal was: to observe vortexes in liquids. At the right time I saw the so called Lavoskop by Felix M. Hediger. There one can really observe a water/air vortex in an ideal manner.

Water Funnel

Viktor Schauberger often dealt with the spiralling of fluids, especially of water, as this improves its qualities. The hopper needs to have hyperbolic shape and the water must be poured in a tangential way, as you may well note in the figure. The funnel is made from copper, because this material is supposed to have a good interaction with the plants.

From the point of view of the owner of the pond (a little lake in a garden) the quality of the water is in a significantly better state than the time before, more clear and the koi carp inside are in good conditions.

Kudu horn

You can observe vortexes in a kudu antelope horn. Not that spectacular, and I even do not know, in which way my experimental object has been altered. My special interest is based on the fact that Viktor Schauberger suspected some special water flow features in a so called Doppeldrallrohr pipe, which had been designed in accordance to the horn.

When water flows through the horn, a pigtailed beam is formed. Right close to the mouth it is flat and dissolves in drops later, which circle downwards.
