How To Increase Vapor Production?

[Caterpiller]

So I see lots of posts on V=IR

And talk about the decreasing importance of R with the newer high power VV/VW devices.

Often posts explain that without the limits imposed by Mech's that sub-ohming is now becoming redundant, as the newer devices can push far more watts at most resistances.

But to be honest, I still find I build between 0.3-0.6 ohms dual coils (Kanthal), and that anything less than 5 wraps or more than 9 wraps perform poorly.

So what is the key to producing more vapor without excessive heat?

I'm leaning towards a balanced heat flux to airflow.

ie: The more airflow available, the more heat flux you can cool. The higher the heat flux the more juice is vaporised, and that watts, volts and amps are less important factors.

I get Ohms law, and don't need instruction in it, and I understand that the greater the airflow, the greater the ability to push more watts through the build.

But ultimately I'd like to understand how to increase vapor production on device "A" with no airflow control, but any choice of coil or power setting, without producing a overly hot vape.

Only way is to play...

Build a 1 ohm coil at 1mm, 2mm, 3mm, 4mm,5mm. Same wire
Wick them the same, same juice.
Fire each beginning at 10 watts and ramp up to the max wattage on your device.

You will find the vape that YOU are satisfied with for THAT topper and battery combo.

Take copious notes.

Cheers

Heavy VG liquids tend to improve vapor production.

It would help to know what device "A" is.

That said the limits are common. You can only build so large before you start to go outside the airstream or start to block flow. Fluid flow rate increases as you use a higher diameter wick. Wick material density has to be balanced. Smaller wire has a faster evaporation cycle rate than thick wire so i'd use lots of wraps of small wire vs less wraps of thick wire to cover the same surface area.

This.
Every atty will perform differently, and every user will have a different definition of "perfect". More surface area is definitely the key though. The more wire you have in contact with the wick, the more juice you will vaporize per given time frame. But you have to balance the heat from the coil with the air flow to keep it from getting too hot.
