OF, while I typically agree with most things you post this time I disagree but have to experiment more to properly refute you (or concede). I can explain my logic though. First you asked how did arizer miss boring out the holes to improve airflow and I think the answer is larger holes would allow particles to fall through and ignite, and the second reason is that the unit doesn't have a heat exchanger.
I will report back after I have experimented more but it might not be until tomorrow evening due to work and a family obligation.
Yes, by all means please do experiment and report what you see. I surely don't expect folks to take what I say just because I say it, I always (I hope) include the reasons for what I say and stand ready to discuss them....science demands no less, right. The idea has to stand on it's own.
I'm sorry I don't know Vapolution.
As to 'particles falling through and igniting' I seriously doubt that, unlike some ofter vapes there is noting down there hotter than the SS cup is exposed....nothing to ignite. The area does in fact fill up with debris as it is. I agree that there is no intentional heat exchanger I can find either, yet another reason I don't think the maker intended to draw in air and heat it to working temperature before admitting it in the bottom through the holes, there's no heat exchanger to do the heating. Units that intend to do this have identifiable heat exchangers?
Here's a bit more 'food for thought' for you. I woke up bothered by this still. I realized with my 'remove the covers and use just the cup' experiment I'd stopped short. More data could have been collected. I had only checked the draw. So I took it apart again and redid it but this time used the 'blow gently into it and see where the vapor come out' technique. I see, I believe,
the majority of the vapor comes out the gap between the stem and cup (some does come out the quadrant openings, depending on the tip of the stem). But IMO the majority is coming coming up through the larger area opening (the gap around the stem). This vapor would
cross over the gap at the top of the cup (you can see this gap looking in the top normally) and will be
combined with that coming up the outside of the cup (through the four holes) and comes out from under the cover being misinterpreted in the above test as all coming from those holes? Without removing the cover there's no way to tell where that vapor is coming from, that which comes up the gap will also come out the exact same place as that through the holes?
I think this is a key point we've all missed up to now, the flow inside or outside the cup is
mixed at both ends. This is why the vents in the Solo body don't matter, the two routes are common just above the cup.
All in all, an interesting discussion, at least to me. I don't think it has any practical use, but what's happening and opinions why are perhaps useful? But opinions (mine included) are only as sound as what they're based on and science that can't be
repeated by others and
successfully defended isn't science but something else?
Thanks much, please do poke around some and make up your own theories if you're not happy with what others have said. IMO that's exactly how it should be.
