Thread with fire demos for students
There are a lot of ways to stylize fire. You can simplify it with rising masses, you can track holes and edges

The fire is rising because the hot particles and gas is lighter than air, this also creates air current that is pretty turbulent for bigger flames or if there's wind/lots of other stuff.
In closed room without wind a candle would be pretty static and won't move much. The smoke from it will rise pretty straight too and may start to curl quite far from the source. If you add wind you'll get the roll, flicker or more chaotic motion.
Using the principle of small rising mass at the top similar to flicker we can build very simple stylized flame like this
We can also simplify flames if we imagine it as waves going to the top
Waves can be further apart too!
Then we add mass at the start and erase more of the shape with curved in part of the wave
That's how we get particles!
Of course there are way more flame behaviors and ways to simplify it. You can imagine flame as a flag or flapping cloth. This is the example from Joseph Gilland's book
