Below is an excerpt from my paper “The Tornado And The Channelized Air Effect.” It is a technical explanation of CAE (Channelized Air Effect) and
should shed some light on how the ST (Synthetic Tornado) works.
Technical explanation
To explain what is going on lets start with the classic ideal gas model. Air consists of molecules, each of which move perpetually through space
until it hit something as another molecule or a surface. At this time the molecule under goes a loss less collision and is redirected off into
another direction. This process repeats it self over and over again for each molecule for ever.
For some people it sounds like gas molecules are violating some written law of physics. Obviously there not, but the feeling is a hint that just
because a law is written down doesn’t mean that it is one hundred percent correct.
To continue lets look at figure 1. Arrow (1) shows the path of a molecule before it hits the surface of an air channel. If the surface was
perfectly smooth then the molecule would bounce off at an angle equal to the angle of incident. However the surface will never be perfectly smooth at
the molecular level so the molecule could bounce off at a typically steeper angle as in arrow (2) or at a typically swallower angle as in arrow (3).
A molecules traveling along (2) will under go another random path correcting collision before one traveling along (3). It is not necessary that
molecule travels from one side to another without a colliding with another molecule. If it does collide then it will, on the average, transfer its
directional bias to the other molecule. This conditional frequency of wall collisions translates to the rule that the more a molecule is traveling
along the length of the channel the fewer path correcting wall collisions it under goes. This rule results in an average directional bias along the
length of the channel for the molecules in the channel. This directional bias is airflow.
Figure 1 shows the air flowing from left to right. The CAE process could easily result in a right to left flow. The direction that wins out is
the result of a tug or war involving the whole system. The direction that results in the largest number of molecules being channelized has the
greater push and will win out. For the hair comb case, air flow coming in through sides and being force to exit through the small bottle neck teeth
ends results in the greatest number of molecules being bunched up and channelized between the teeth. Thus we observe air coming from the ends and not
going into them.
It is easy to rationalize that, on the average, each molecule wall collision results in a very small increase in air velocity. Thus the change
in velocity is directly proportional to the total number of wall collision. This is directly proportional to the total channel surface area and
inversely proportional to the air velocity. The total ram force is proportional to the air velocity squared. This means that the change in force is
proportional to the produce of the velocity and the change in velocity. The final result here is that the total increase in ram force is directly
proportional to the total channel surface area and independent of air velocity. It will be seen later how this independents is the key to producing
real power from CAE.
