It is very interesting the similarities between captive vortices and magnetron swirling electron clouds! The type of vortex generator I’m referring to has proven to be extremely elusive in terms of internet searches. I have one that is rather large by the usual standards that I have seen these as. It is about 40 cm in length and 12 cm in diameter at the widest part of the taper, it reduces to the exhaust port at about 40 mm. I picked this one out of the dirt that it was half buried in from being run over by the giant tires of the industrial forklift that they used there in an industrial junqueyard!
The one I have has no data plate on it, and it was also made for some serious gas or steam pressures due to the thickness of the walls and the fact that it has no damage from being repeatedly run over by 24 inch width 6 foot diameter tires for an undetermined length of time. it had been there in the dirt for quite a while because it had absolutely no paint anymore and was completely uniformly surface rusted. This one was a freebie from the proprietor (a friend) and was completely filled with dry mud.
I did not know what this thing was for a few minutes, but standing there examining the completely dirt filled cone shaped tube, I immediately began to grasp what the thing did by simple virtue of its shape and fittings. I knew for certain that this device did generate a captive tornado inside. I took the unit home and dropped it in the doggie bathtub full of water for it to soak overnight and soften the mud plug. I did clean the unit up and did a inspection sufficient to determine that the object was still a functional device despite its uniform surface rust. I have seen these before associated with some industrial boilers and other gas/vacuum systems, but have yet to get any names of manufacturers for these. They are used as a kind of exhaust ejector, and I know they are capable of some very high quality vacuums!
I would sure as shit like to know what the industry name for this device is!!!! I find the magnetron an intensely fascinating device from the fact that it functions on Michael Faradays mercury rotator principle in the form of an electron cloud motor of a sort, and that this principle is very useful for much more than just a magnetron oscillator!
I know a “Tesla Coil” proper is essentially an air core device, but the iron cored automobile ignition is a direct offspring of his air core device, and that the point type ignition actually was patented by Nikola Tesla in the very late 19th century! also those nice ballast transformers and oil burner ignition transformers all work on the reluctance bypass principle of Teslas constant wattage and constant current transformers patented between 1888 and 1890 as additions to his transformer patents.
I hope I can find someone who knows what my curious tornado cone is called!
