Difference between macro and parallel builds

[dyanaprajna]

My first build was a 24 gauge Kanthal, 3 mm ID, 7 wrap @ .4 ohms. I'm wanting to try a parallel build at around .2 ohms-basically I'm looking for more clouds. If I'm using the 24 gauge Kanthal, how many wraps should I make a parallel build? I'm planning on staying with 3mm ID, but I can change this if I need to. Any help would be greatly appreciated.

Steam Engine is your friend. Is this close enough?

 

[dyanaprajna]

Yeah, that's pretty close. I was thinking it was going to be around 7 or 8 wraps.

You called it well. I've used some parallel build and liked them so it's worth a go.

Note this is for single coil. Dual would be half the ohms. Dual at same as single ohm...twice the wraps approx.

A 8wrap 24g parallel coil is going to be huge. Dual coils that way will also get really hot.

OK, so I may need decide on a different build.

Or same build using different wire.

I wonder if a dual 24g Kanthal twisted would be any better?

 

[93gc40]

Maybe maybe not.... twisting will increase ohm rate and capacity but probably lower heat flux..... same I'd and wrap count a higher ohm coil that need more power to achieve heat of lower ohm coil.

Depends on the goal.

Personally I prefer twisted to parallel, Flavor wise and para for clouds.

What are you using for an atomizer?

TFV8 rba.

I was playing around with steam engine, and noticed that, keeping the same wire and gauge, and same target resistance, if I lowered the ID, it would require more wraps, without changing the heat capacity. So, would simply going from a 3 mm ID to, say, a 1.5 mm ID give more surface area, hence, bigger clouds? Or would it stay about the same? And how would this effect flavor?

Going from 3mm id to 1.5mm id will give you less surface area not more.

 

[dyanaprajna]

I kind of thought that might be the case. I did a 6 wrap at 3 mm and .3 ohm, and it said the same resistance at 1.5 mm would be 8 wrap (or something similar, I can't remember the numbers off the top of my head). So I thought that might give more surface area, but with a smaller ID, I guess it does give less surface area.

Any coil that uses the same gage wire that has the same final resistance will have the same surface area because it will be the same length wire.
