Vapor experiment Color Theory, with taste impact.

[ColJD]

Hi, I have been experimenting with vapor production.
Using simple carbonized stainless steel mesh threaded with nichrome wire.
Using some knowledge I once read on water vapor
" When you boil a kettle you see white cloud. This white cloud is not steam (vaporized water), the cloud is most likely water molecules that have condensed from steam now being carried by the steam and soon to 'rain' down.
Steam itself is transparent to the human eye as the molecules are spread far apart"
-
Ok to test this I super heated e liquid under pressure and pumped the vapor into a clear heated pyrex pressure flask.
initially it appeared that the flask was, empty or just had air in it. But there was an overpowering smell of blueberry the flavor of my e liquid.
Now I slowly cooled the flask so as not to break it.
Result as the flask cooled to about 90C the pressure obviously dropped,
and a white cloud or mist appeared that then rapidly caused the flask to appear full.
The flask then cleared and a few drops of eliquid appeared in the bottom.
I had started with 2 ml and I'm guessing less existed.
- What appears to me is that the clear true vapor is responsible for taste, however the nicotine or throat hit must come from condensed eliquid vapor.

I d be happy for criticisms or debate of what I'm doing in my quest to design a better vaporizer.

You taste the flavor additives, the vapor is just the carrying agent for the molecules that your tounge senses as taste. From what you describe, I'm not really sure what your trying to achieve or prove. To keep from getting too complicated I'll submit the following.

You cant see true water vapor as there is too much space between the molecules for the naked eye to pick up. Just like you dont see the nitrogen and oxygen in the air every day. When the gas cools and begins forming droplets is when you see the white cloud.

The clear vapor and the cloud are the same thing, the first is just in a more excited state than the latter.

From my little experiment that is exactly what happens.

I am trying to understand the process to have a better knowledge in respect to building a better device.

One big problem I see with the current atomizer type system is the regulation of the pressure within the device.
As vapor is produced the pressure increases rapidly, however low pressure is essential for efficient vapor production,
If the vapor is not removed by lowering the pressure eg airflow and inhaling, the battery will be just supplying energy to heat the vapor, which is detrimental to the experience.
Thus it could be assumed that a lot of white cloud shows that the vapor has been heated to just over the ideal temperature to be able to condense quickly on mixing with the airflow.

This should really mess up your expected results then.

Exhale in your hand. It's warm right? The air coming out of your lungs is heated to your body temperature.

Now, take a good puff from your ecig, inhale, and blow it into your hand.


How does it feel?

Strange reaction for a liquid that was boiled to produce vapor, eh?

 

[ColJD]

If the liquid was at 1 bar pressure it would boil at aprox 133 C
Decrease the pressure and the temp drops.
But this doesn't really explain this.
