The corona devices are made with a perfectly centered wire so the wind in theory is in all directions but still some might be circling and you can feel it. At higher voltages (but before breakdown) it's more noticeable. And if you do this between a metallic plate and your hand with a very low current (otherwise it hurts), when air starts to ionise, you feel some cold air moving on your hand.

    You should add that the left plate gets a black spot on its surface.
    That is where the positive ions go - the carbon+ ions.
    And for the record, there is always an equal amount of negative and positive produced.
    The flame is asymmetrical because the positive ions are bigger than the electrons.

      Socket 60 Hz AC probably wouldn't do anything, though with a high enough voltage you might see a breakdown facilitated by the presence of the flame. If you could modulate the frequency to match the oscillation of the flame (looks like 5-10 Hz for this flame) you might see a resonance. For maximum effect, the E-field should be oriented vertically.

    I hooked my oxy/acetylene jewelers torch to the positive side of my HV power supply once (yes, I took all necessary precautions and isolated everything with ground connections and flashback arrestors on the gas lines at either end of the hose), after I coincidentally noticed my raw acetylene flames were attracted and repulsed by the anode/cathode of my HV system, I turned the oxygen off so it was just raw acetylene burning and then held the cathode in front of the flame. If you ever get the opportunity to try it it's mesmerizing, I was fascinated as I watched a bug fluffy cloud of soot growing into dendrites off the cathode, rather quickly I might add. I wish I had recorded a video of it, maybe I'll have to haul my torch set out of the garage and dust off the HV supply one of these days and record a quick video of it happening. I could very well be wrong but I think some of the acetylene gets transformed into carbon nanotubes, I remember hearing about methods of growing carbon nanotubes that involved an acetylene gas filled reaction chamber that is burned under high voltage but I could be remembering a dream, don't quote me on that. Regardless, it's a fascinating experiment to see a flames properties when exposed to high voltage, especially when you can grow big fluffy-cloud dendrites of complex carbon structures with nothing but a bit of burning acetylene and a cheap ebay 20,000 volt transformer lol.

    The positive ions would tend to be of smaller sizes than the negative ones. This would tend to give them move ability to move through the air. Also, H+ would be very light and tiny, so those would move fast and far. If you used AC, you could likely setup so interesting resonances with the flame.

      Except that in reality, free electrons barely attach to air molecules to give negative ions and the few created are short lived, hence free electrons are the main electric (electronic in this case) current flowing. In plasma physics, the electronic current is always greater than the ionic one and free electrons make the streamers for example. Although here, we don't have a plasma admittedly. In any case, free electrons are much more mobile than positive ions and their mean free path is much longer. Also, there is no hydrogen in the air (infinitesimal traces).

  • @craig4320
    @craig4320 3 ปีที่แล้ว +11

    In blue flames like a Bunsen burner the light comes from ions recombining, but in yellow flames like candles, most of the light comes from incandescing soot particles. In a clean yellow flame the soot particles are quickly burned when they reach the higher oxygen regions away from the center of the flame.
    Overall the flame is expected to have a neutral charge, with equal numbers of positive and negative charges. You can see from the spot of soot on the negative plate on the left that the soot has been attracted to the negative plate. Therefore the soot particles are positively charged. A reasonable conjecture is that the negative charges are electrons, which would be attracted to the positive plate on the right, and the atomic ions, like the soot particles, are positively charged.
    It certainly would be a good idea to try the experiment with a soot free flame. Bunsen burners have metal parts which would be prone to sparking in the strong electric field. candles easily flicker, and are likely to extinguish when they are flickering. It would be easier to claim that a flame was extinguished by the separation of charges if the flame was not flickering.
    The important variable is the electric field gradient, which depends on the voltage difference between the plates of course, but also is greater when the plates are closer together. At the end of the video, when the plates were brought together, the gradient was raised.
    A Van de Graaff generator could easily generate the 25 kilovolts, but this experiment needs more current. If you had access to only a 5 kilovolt power supply, you might be able to run the experiment with a smaller plate separation and a very small ceramic burner. As far as I know, sufficiently small burners are not easily available.

      You can calculate the approximate capacitance fairly easily. The plates seem to be about 100 mm in diameter, and are about 100 mm apart (my guesses). C = epsilon_0 * Area / distance_between_plates The permeability of air is about the same as for vacuum, so epsilon_0 is about 8.854e-12 Farads/meter so.... 8.854 Farads/meter * pi * (diameter/2)^2 / 0.1 meter = 0.695 picofarads. You can now compute using the capacitor discharge equation V(t) = 25 kV * e (-t/RC). R is given in air about 10e9 ohm-meters. (but varies with temp, humidity, etc) with .1 meters, we have R= about 10e8. So, after 1 second after removing the 25 kV source (that is, t=1), we compute V(t) to be .... a very tiny number ( so small, my calculator returns 0.0). Now, Capacitance = Charge / Voltage; in this case, then, Q (amount of charge) = 0.695 picofarads * 25 kV = 17.4 nanoCouloumbs. The Energy stored in this capacitor = 1/2 * C * V^2 ; in this case 217e-6 Joules. Now, if you get the plates 'too close', you can ionize the air itself, and there will be a nice spark between the plates. You need about 3 kV per mm to do that; so in this case, being 100 mm apart, you would need about 300 kV to get a spark between the plates. Still: DON'T TRY THIS AT HOME unless you understand this sort of thing COLD.

      The problem is (based on my understanding) it wouldn't really stop the combustion, it would just pull away the "flame". So it would be ineffective against anything that burns without a flame e.g. coal.
      Also, it only puts out the candle is because the combustible matter is concentrated in a small area (the wick). If you had more fuel to the left and the right you might in fact increase the spread of the fire.

  • @crusinscamp

    Interesting demonstration.
    The flame is electrically isolated from ground. Most candle wicks contain a fine metal wire to keep the wick standing straight in the flame. It would be interesting to ground this wire at the base of the candle to ground the flame, thereby providing a source of electrons to the flame of the candle. The flame may develop an electrical bias due to the difference of ion mobility in the electric field.
    I'd like to understand why intensifying the electric field puts the flame out.
    Try running a small stream of water in a unipolar electric field (you can use a charged piece of plastic ). I had a physics teacher do that once to surprise the class.

The ignitor is continuously energized with twenty four volts A/C which is conducted through the burner flames to the grounded "flame rod:" this is known as "proving the flame" or "flame sense." If one or more burner flames extinguish or ignition fails on any burner for a short, set amount of time, the gas valve is shut off. Excellent visual demonstration.

It used the flame envelope to push air AKA a speaker. I got a 400V DC power supply from my pastor (who was also an electrical engineer/HAM operator) and modulated it with a signal from a cassette player. The weakest part of the setup was the electrodes which needed to be placed inside the flame. I used nails, but they deteriorated pretty quickly. Trumpet sounds were so crystal clear (BS&T of course).

    Humidity in the air (H2O) goes doink, aligning itself with the electric field surely since it is a polar (non-symmetrical) molecule, slightly negative on the oxygen side (pointing toward the positive plate) slightly positive between the hydrogens pointing toward the negative plate. CO2 is not polar, it's straight across. In water, it only takes 2.3 volts per molecule (if I remember right) to line 'em up and strip them apart during electrolysis to make hydrogen and oxygen gases when they recombine in like pairs. (Lots of current though, unless pulses/frequencies might help).
    Just have to wonder if they ever separate in a strong electric field in air, first time it ever crossed my mind. If so, would we be losing some hydrogen floating upward with our 100 lightning strikes on earth per second?

      What you heard was a reference to what's either called conventional current, or sometimes 'physics current', called 'conventional' because at the time that electrical theory was first being characterized, we had no idea that the electron itself existed. We only knew that _something_ with many characteristics of a fluid was discovered which could flow through certain solids(conductors), and it seemed sensible to assume that if it(electricity) were fluid like it's probably 'pumped' through the solid by positive pressure rather than being 'drawn' through it by negative pressure.
      It's sometimes referred as physics current simply because positive charges, even theoretical ones, are a bit easier to deal with than negative ones. Take the right hand rule for instances. If youre conceptualizing a flow of positive charges from positive to negative then the right hand rule will tell you exactly what direction force is applied to the charges if they pass through a magnetic field. If you use the right hand rule for electrons flowing from negative to positive, then the answer provided for the same condition must be flipped 180° to be accurate.

    When a candle burns it creates a convection current as the hot air, now being lighter, rises and is replaced by colder air underneath. The hot air rising has less oxygen than the cooler air underneath it. This is why we get that shape that we do. Fire in space forms a ball since there is no gravity moving the hotter and lighter gases up. When you create the electric field wouldn't that interfere with any normal airflow? Couldn't that prevent the CO2 from being able to move away from the flame to create room for O2 to reach the flame?

    I’m pretty sure you can also reproduce the effect using 5kV. You’ll just have to bring the plates closer together. Electric field within a plate capacitor is E=V/d, where V is the voltage between the plates and d is distance. Correct me if I’m wrong!

      Yes. You can try but the plates will then start to spark as the air resistance breaks down. It has some effect but not as good. 😃

    This is kind of like a pilot safety system on a gas fired furnace. Unburned natural gas does not conduct electricity while a pilot flame will conduct electricity. An ac signal is changed to a basically dc signal by using different size conductors for the signal so a short circuit would not defeat the safety, It is called a flame rectification system. The older style heaters used a thermocouple. which develops a 30 millivolt signal which energizes a solenoid which allows gas flow.

    Fun video. It would be very interesting to now what voltage is being applied at the different points when the flame is affected. Also, the flame would look much better if you turned down the exposure on the camera (and possibly the contrast too). Would this work with a much lower voltage if you put the plates closer and used a smaller camera? How low can you go? It would be cool to see different types of flame too.

    Is there a way the burning efficiency could be monitored for this? Maybe investigate what happens to flame fronts within the field? How big/small a burst of current would be needed to affect the flame?

    • @oddball_the_blue
      @oddball_the_blue 3 ปีที่แล้ว

      Further thoughts lead me to wonder what would happen of you had a hole between each plate? Which leads to to thoughts on applications for 2 different purposes... Then further thoughts on if pulsing has any effect and what frequency/voltage/wattage combinations would induce useful effects. Enquiring minds and all that, if it's already been investigated I'd be interested in research papers.

    Your videos remind me of elementary school. I love watching these. Also, reminds me of Science Fair experiences.
    when i was little, like 6th grade, of course our school had science fairs and wanted the students to participate.
    I wasnt very smart but was happily interested in science and effects of physics on mass / objects of different masses and material makeup. my project was on effects of gravity on objects, when underwater. had seen a lot of movies at that time during the 80's , and was fascinated with metals and weightlessness.
    I attached different paperclips , 2 sizes the big ones and small ones, to a magnet at the top of a fish tank full of water, and tested how many the magnet could hold while dangling underwater, and then tested the same outcome outside of water to see the difference. i dunno... something about it made sense to me as a kid lol ....
    It wasnt a great project... however presented well. but i feel like i never grasped the concept that was teasing my brain into the desire to create the test in the first place....
    😂 ... laughing now.
