The transition from streamline flow in a pipe (parabolic velocity distribution) to turbulent flow (uniform velocity distribution) can be seen as a transition from isotropic micro vortices with their axes perpendicular to the direction of flow to vortices with their axes parallel to the flow direction. <<<<<<<<<  Notation by Richard.. as neat a description of a liquid vortex as I've seen Now if BR electron orbits are oriented in the same manner as turbulent flow vortices then a collimated beam can be expected. We recently used a "Q" beam lamp to study a new "Coanda Effect" ( double stacked bladed propeller with venturi effect between blades) being tested in our windowed water tank. The bright lamp permitted us to watch the thrust characteristics of the propeller. A reverse vortex appeared.  It projected from the recess in the prop hub( used for the prop mounting bolt)  in a tight straight vertical pattern downward from the vertically mounted 3450RPM vertically mounted electric motor driven unit. The vortex did appear to repeatedly " cycle" in formation and decay. Drat that welder of ours for not having the new equipment finished for our 10,000 RPM run tests to see if we can get a UV and perhaps a gamma event from increasing the speed . Yes! we have a RAD meter handy. The formation of the vortex is not nearly as interesting to us as the "cycling". This indicates we have a capacitor event taking place. hmmm!! Richard
