Talk to me about wicks.

[Powerman]

This might be a silly question, but do wicks wick when the coil fires? Does juice continue to flow?

I ask because it seems to me the coil would vaporize the juice in the coil and that's it. I mean I can pull too long and the wick burns. I'm assuming the center gets dried out and starved.

They wick as one takes a draw, unless one is auto dripping on a genesis style atty...

A wick will saturate itself with juice and continue to do so as the juice is vaped.

put the end of a paper towel in water and watch the water absorb ..... same thing with the wick ...... of course wicked improperly with a kink for example and you can be getting dry hits because the juice is not getting a good path to travel

I know what a wick does and how it works. But when you flash liquid to vapor, and increase temp and pressure, things change.

We want coils that heat inside out. But once things are up to temp, juice will flow to coil. But if it is vaporizing once it gets to the coil, then it never gets to the middle of the coil. I'm sure heat, length, and diameter play a big role.

We obviously know what can exceed the limits of the wick or we would never get a burnt hit.

Maybe I'm misunderstanding your meaning, but to me the point of the coil heating from the inside out is to ensure even amperage is going to the coil.

You tell me. Seriously, I'm no expert. I don't know why we want contact coils heating inside out.

 

[CrazyChef]

Even distribution is what I've always figured.

With the chemical process involved with wicking the fluids being vaporized will speed up as the heat increases. If you have a hot spot in you coil that is away from the center it will stop the flow at that point. If you interrupt that flow any point behind it will not receive juice enough to keep your wick from drying out and burning. Resistance wire has small inconsistencies that will cause the current flow to get trapped in certain spots from the terminal points. That is why I wrap my coils as evenly and tightly as I can to save time in working out those hot spots. Terminal spacing is bilateral so chances are if you have one hotspot that you see there will be one on the other side of the coil in nearly the same area of the polar opposite. If you work your coil out to have the even heating from dead center burning your wick would be an improbability. Electricity and vape fluids are both flowing when the process is started. As long as your coil is built and tuned properly and your wick has ample access to the fluid, it doesn't matter if you are vaping straight vg (as I do undiluted no pg or water added) you won't burn your wicks until they get too old and gunked to flow.
