Anyone with a High Speed Camera on the forum?

Hahahahaha I love this guys!

Not yet, it was sadly an unexpected working weekend for me (didn't even exercise my right to get REKT :() and it's been a mad house ever since. I'll make some time one of the evenings this week.

No problem ace_d_house_cat ... I guess paid work has to come ahead of our hobbies :rolleyes:
 


Here's a link to the actual video on my Google drive, actually took this video in Jan playing around with the slow mo cam and just rewicked the brunhilde


Some feedback on the file ...

When the video is examined frame by frame, the majority of vapour certainly seems to emanate from the wick ends, so status quo, there's merit in confirming this phenomenon ;)

I also removed the locating tabs from the cap off a Recurve Dual, so that I could place its top cap on, with the air inlets facing the coil ends as apposed the sides of the coils, and there is a substantial difference with respect to flavour, (using a single spaced plain wire coil).
It does need some more work to direct the air closer to the coil end tho' to prevent vape dilution.
I'm now in search of a second Recurve, (or two other identical and preferably simple decks), so that I can do some back to back comparisons between air flows.
 
I love it! ... so the pops we all know about, and some of those droplets find themselves in your mouth too, however if you look to the left of the coil, that's what I noticed, that trickle of vapour, which prompted the thought. I then tried with a loose-ish wick, and saw it happen on both sides of the coil, and NOT the center! :)

EDIT:
I can't get enough of this :campeon2: ... I would love to see the video frame by frame, as it looks to me like that pop happens on the right side of the coil ... now this explains how Zeus get it right by directing air on the ends of the coil as apposed the sides, it also substantiates why wicking density is more of an issue with some tanks than others.
You might be on to something with that statement. If I turn my RDA cap on the Tobhino inline with the coil I have noticed a difference in flavour and I also get a bit more airflow.

I'd certainly recommend giving it a try as you've done, to confirm what I have observed to date, namely that the vapour from a coil definitely emanates from the ends, more so than the outer surface at low to medium power levels ... I would require much better high speed camera footage to be able to confirm what happens at higher power levels though, also;
Subjectively ... the vapour density seems to improve when the air inlets face the coil ends as apposed their 'normal' position of facing either the bottom or outer sides of the coil, I've tested this on Zeus X and Recurve Dual decks to date and both seem to improve, however, again;
I would require some non subjective method of proving this phenomenon, and am having a look at building a fairly simple test jig that can supply 6 litres of air per minute, (a typical DTL draw), and feed it into a spectrometer for density and quality comparison.
If all of this goes well, then we'll end up with a method of scientifically measuring specific vapour density, and should also be able to resolve the ongoing vapers argument of which coil types, wire types and wrapping methods are best as well ;)
 
One can simply imagine a dual micro chimneys RTA with air outlets directly on top of the coil ends reducing the Vaper dilution and producing a phenomenal flavour! I can see the Ecigssa RTA taking shape as we move on into this thread!

You may well be correct @Grand Guru :) ... We're only talking about the coil atomisation in free air at the mo', and things behave very differently in a vacuum, to which the chimney, (or chimneys?), would also need some work ... ideally they should also be tapered towards the tip to maintain the vape density as the vape cools, but the jury is still out on where it / they should be placed ;)

I love the idea of a Ecigssa RTA BTW :inlove:

That's how I've been using the Tobhino almost since I got it. I think I have posted it on the forum somewhere. I set my coil and then turn the cap.

Spoiler alert. @Intuthu Kagesi is making it happen!

That's fantastic news :) and supports the testing I've done on the Recurve and Zeus. I would still like some more high speed footage of other coils types to confirm whether this phenomenon holds true across the range of coil and wire types, and in the meantime, am just going ahead with my test rig to automatically suck and dump a measured quantity into a spectrometer for comparative analysis :).
