, for me the air is better "swirled" (it is pretty this word
) in the other direction, this example is wrong, just see the size of the rubber hose (which is even oval!).
the elect is there, but it's probably not that place!

hello, oval air cyclone: it works perfectly ...
air and water are fluids that move regardless of the channel through which they pass. So round, oval, square or bizarre, they pass with just disturbances related to the forms precisely. VSLAs only introduce a form to these fluids to avoid the negative effects of disturbed fast flows.
So
experimentally No matter the number, shape, size of the fins, the only important point is to initiate these vortices (at most they can disturb these streams moreover.)
hello, I find that in the case of aerodynamic air cyclones (WITH) the vortices are coarse with 3, 4, 5 blades, and become finer with 6,7,8,9,10, etc. blades, if the blades are short, the streams lengthen and lose their rotations, if the blades are long, the vortices go further in their path of the hoses ... to the admission chambers ... if the angles of the blades are around 45 ° the flows turn but advance slowly, if the angles pass 55 ° up to 65 °, there their rotations and their speeds are effective ...
observations made by experiments, and reactions under the accelerator pedal, and the revving, and ribs ...
