Hey all. Since I'm a newb that's still learning and currently do not have the space to set up a proper work station to build my own wire, there's not much I can do to contribute to the forums outside of posting my setups. Hopefully this thread will be seen as a positive contribution to VU and help gain better understanding of what goes into building a solid atty to achieve our desired outcome which is clouds, flavor and/or both.
A combination of things have led me to create this thread so here's a short list.
1) the name and my building experience with the OBS Engine Nano.
2) my recent build on the Goon 22.
3) my background of being a gearhead that loved pulling engines apart to build more power. Did a lot of street racing in the 90's.
4) the names of two atomizers, the 454 big block and Jai Haze's new 502.
Volumetric Efficiency is defined in three different ways according to Wikipedia, and I absolutely relate and agree with how wiki defines it.
https://en.m.wikipedia.org/wiki/Volumetric_efficiency
Internal combustion engine.
"Volumetric efficiency in an internal combustion engine design refers to the efficiency with which the engine can move the charge of fuel and air into and out of the cylinders. It also denotes the ratio of air volume drawn into the cylinder to the cylinder's swept volume. [1] More specifically, volumetric efficiency is a ratio (or percentage) of the mass of air and fuel that is trapped by the cylinder during induction divided by the mass that would occupy the displaced volume if the air density in the cylinder were equal to the ambient air density. "
Hydraulic pumps
"Volumetric efficiency in a hydraulic pump refers to the percentage of actual fluid flow out of the pump compared to the flow out of the pump without leakage. In other words, if the flow out of a 100cc pump is 92cc (per revolution), then the volumetric efficiency is 92%. The volumetric efficiency will change with the pressure and speed a pump is operated at, therefore when comparing volumetric efficiencies, the pressure and speed information must be available. When a single number is given for volumetric efficiency, it will typically be at the rated pressure and speed."
Electronics
"In electronics, volumetric efficiency quantifies the performance of some electronic function per unit volume, usually in as small a space as possible. This is desirable since advanced designs need to cram increasing functionality into smaller packages, for example, maximizing the energy stored in a battery powering a cellphone. "
Our atomizers function very similarly to an internal combustion engine with a few minor differences. Those differences being no volatile fuel or spark to ignite it. However, in a sense our juice is our fuel, our coils are our spark plugs and the inside of our atomizers is the combustion chamber where all the magic happens to create the vapor/flavor ( exhaust ) we all desire.
I'm going to use two examples of how this comes together in our rta's and rda's.
1) the Engine Nano and one of the primary sources that sparked the idea to create this post. As the juice tank drains and becomes filled with air again, the Nano loses VE due to air from the juice tank somehow being sucked in and mixed with the air coming in from outside of the atomizer. How do I know this? Because as the juice tank drains and becomes back filled with air, I have to increase the wattage as compensation to achieve the same result as when the tank was completely filled. By the time I've drained the juice tank down to around 20% of its total volume, I've compensated with an additional 5-10 watts to keep the flavor and cloud production the same which in turn drains my batteries more. It's a trickle down effect. It's this inefficiency and overall volume size of the combustion chamber that led me to building bigger coils for my Nano's. Filling up the combustion chamber with more coil just makes sense provided the batteries can sufficiently supply the additional power needed and that coil is wicked properly. Here's where VE was maximized, by increasing the coil size and thus increasing the amount of wick to supply the larger coil, I decreased the amount of air available in the combustion chamber which has allowed me to vape at a lower wattage while achieving better flavor and clouds. I'll go ahead and speak on my batteries behalf and say they are much happier when they are running cooler and lasting longer in between charges. Less stress will only increase the longevity of the batteries as well the safety aspect of them.
Now let's take my most recent purchase, the Goon 22, as the next example. When I purchased that little beauty almost a week ago, I had a choice between the 22 and the 24. My dude at the vape shop was kinda surprised when I chose the 22 over the 24. 1) I just really dig 22's for flavor so it's just my thing and 2) I knew if built it correctly I could stuff that atty full of coil wire which means more wick and juice and less volume available in the combustion chamber for residual air. Volumetric efficiency.
I'd like to use another example if you are still with me, hopefully you are. I have both the 22 and 24mm Herakles rda's. The 24 is killer for build space and juice well depth but a killer ( in a bad way ) on flavor as well. Due to the huge amount of space with the combustion chamber and juice well, I cannot achieve the flavor the 22 gives me. Which is sad really because I usually run the 24 with dual larger coils at 5mm ID and have even tried 4 coils at 3mm ID but the flavor just isn't there. I admit, the clouds can be very, cloudy lol. The 22 I run a single coil between the velocity posts with 7 wraps spaced and a 4mm inner diameter which gives me some really nice flavor, much better than the 24 using dual or quad coils and using less watts which keeps my batteries cooler.
So, subtle differences aside, we are tinkering with small engines. Atomizers require air intake like an engine, fuel ( juice ) like an engine to create exhaust ( tasty clouds ) like an engine.
I genuinely hope this helps and is seen as a contribution to the VU forum because I really do dig this place and appreciate all I've learned as well as the folks that have taken the time to help educate me.
I've never met or even conversed with these folks on line but I would like to take the time to thank, first and foremost, Battery Mooch for his efforts in battery testing and continuing to harp on the safety aspect of using and storing our batteries. You Fucking rock man! Would also like to thank reviewers such as Matt from SMM, GrimmGreen, Vaping Bogan, Mike vapes, DJ LSB, vaping Fagan, Jai Haze, Ghost Vapor and vaping with Vic for their videos that have taught me so much in such a short time. I know there's probably a few I forgot so I'll just go ahead and say, my bad dudes.
One last thing we should all keep in mind. A finely tuned atomizer on a properly functioning mod will go a long way in battery safety. If are to continue the good fight against the FDA, we must do our best to not become a part if the statistics they will use as fuel against us all. In other words, don't be a Fucking idiot with these high powered devices by pushing them too far to where we become injured and thus giving the FDA fuel against us. Let's simply use our brains to out-witt the FDA half-witts.
