Drip Tips can Solve or Create Problem (maybe they're more important than we thought)

[StrappedKaos]

I have always wondered why as a whole no matter where we go in the vaping world design wise no one thinks about the fluid dynamics of it all.... Ok so bare with me, I have fabricated and designed intake and exhaust manifolds/Headers/Air boxes and the likes for companies such as Bill Davis Racing(Nascar Team) I don't have the access to the same tools anymore so I can't make what in theory would work but I can share some ideas since I wont be able to help otherwise.
Consider rifling in a drip tip and top cap also

I have yet to see things like venturi effect really adopted to our hobby....Maybe on a small side but still it can help and all thought some have somewhat done just that no one has micro air tested or even attempted to test the effects of the smallest changes in the builds that I have seen. Much to be perfected in the future.

Consider this and see what you get from it -Warning be careful what you try this on- Take your drip tip off, and pull thru the intake air hole while vaping-the part we drill by the coils(Don't do in public) Then put a couple diff. sized tips on and keep trying, Any thing changed? I have found that if you could build a top cap that pulls air from the side thru holes by the wicks and incoming air comes from the place we normally place a drip tip it boost all the things we look for, Flavor and vapor production. Even Directing the air where we want it has a huge effect on the total outcome. Like small tubes that are velocity effect that help the air spin in the top coil after it hits the wick(imagine the tubes at angles and not just holes in the top cap) Sorry im horrible at explaining these things.

Much like stated here already air reacts the same in many environments, I could run 3in. air intake to 4-3in runners in a manifold and to 4-3in exhaust runners to a collector that goes into a 2in exhaust pipe and it could create a great low end but by running an 4in exhaust it kills the low end and overall output is raised....many wont understand my simple theories but it is that just simple since i'm not going into great detail just expressing my thoughts on how much a quality R&D RDA could produces loads of everything we would want and solve many issues we have......... Why cant I have my mill and lathe at a time like this? I could have created so many great products on breaks and after hours lol!

I see what your getting at. Basically our RDA chamber would be like the float bowl on a carburetor, and we would indirectly be drawing the vapor out of the chamber by way of the venturi effect. I think this would be a cool looking top cap. As an engineering student I have full range of the machinery at school (CNC mill, CNC lathe, mill, lathe); I may try making something to test the concept.

In the end I think doing something like this may have some problems. I think we would have to have a big enough hole coming from the chamber to the venturi (like 3mm) to flow enough vapor (the hole in the chamber wall would to be much lager to compensate for the wall thickness of the mechanism, think drip tip hole size). This may cause the device to be rather big and clunky. Another possible problem is I think the vapor will be thinned out much like gasoline (a fluid like vapor) is thinned out/atomized into the air in a carburetor. This could reduce throat hit (a positive or negative) but could also reduce the vapor to air ratio (reducing vapor density and flavor).

If I get a chance to test the concept I will do it by making a drip that looks like a capital T (T). One would have to suck from the side of the drip tip (instead of the top) and it wont be in the ideal location (on the side by the coil), but the concept is the same, just sideways. I am interested to see if the performance will be the same, better, or worse.

On a side note most clearomizers, carto-tank systems, and Kayfun/Russian tank wick/feed juices by or assisted by a venturi type effect.

Something cool I have coming in the mail if you are into RDAs. I think its a pretty cool drip tip innovation, plus I got the titanium one and I love titanium.

Anyway thanks for bringing up this neat idea. It's at the least something for me to tinker with when I'm bored/not-busy.

I agree, the room needed to make some of thw affects I am after might be ro great. Maybe by changing the diameter/angle/ and the distance of the tube would allow user to control the affect. I.e. if the in coming air hole had an adjustable and replaceable tube the would stick out that you either slide thru or screw into the hole allowing you to manipulate the angle and amount of incoming air. Instead of building a coil to match the air hole you can build the coil in a better spot and bring the air to it where ever you may want it. I notice the aqua and kayfun and some others have a chimney that starts out wide on deck and tapers like a velocity stack when reaching drip tip. Still wish I had the means to create for these experiments

Much better tips than ninja's.

Venturi tips, just as you suggested a couple of months ago

Yes it is a venturi but so is the ninja mods, any drip tip with a hole in the side creates a venturi when used on an RDA. If diameter in a flow decreases (chamber of RDA to drip tip opening) velocity increases inversely of pressure creating a low pressure zone in the drip tip compared to the atmospheric pressure. This pressure difference causes surrounding air to flow into the openings on the drip tip. (I'm an engineering major taking and acing a course in Fluid Mechanics).

Saying that tip is better is only based on personal opinion. Sure if the bore size of the drip tip is smaller you could get a way with smaller holes (because of the higher velocity produced and a bigger pressure drop), but the ninja mod tip is infinitely adjustable to small holes so that is not a problem. I aslo can open the holes so much that I can get more vapor out of a disposable cig-a-like.

Anyway Ninja Mods beet them to the punch but marketed it a different way (not using the term venturi). We were talking about using a venturi to draw the vapor out of the chamber not drawing the surrounding air into the tip. None-the-less it is another great drip tip I have to get as I am a drip tip fanatic, Great Find!!!

A little Necromancy for ya, but I was just so happy to have read this. This whole thread is GREAT!

Either- A: I'm NOT totally insane, or B: Those of us thinking along these lines ARE totally insane....

and this too. Absolutely made my day.

enter: the tobh slam cap. airflow is no longer a concern.
