A flam e tornado is pretty self-explanatory, it is just a flame being spun in circles{explain how fire tornados are created and what they are, maybe talk about them in the real world}The fire tornado works by “the rotating screen [giving] the air molecules an initial spin (called angular momentum or rotational momentum). The rotating air molecules collide with the hot air rising from the fire and the flame twists into the shape of a tornado” (“Steve”). Fire tornados actually happen in the real world, most commonly found during forest fires when winds blow in between trees.
I tested to see if increasing rotational speed and adding vents to the bowl would increase flame length because both would promote air flow, which would allow …show more content…
The highest with the faster speed and no slits was 9 inches, and the average height was 5.35±.67 inches. The highest with the slower speed and slits was 11inches, and the average height was 7.38±.88 inches. The highest with the faster speed and slits was 10 inches, and the average height was 5.69±.67 inches. The trials with the slower speeds both had higher averages and higher maximum s than the faster speeds’. The trial with the slower speed and no slits did have a larger maximum than that of the slower speed with slits, this could be due to the fact that the bowl might not have been perfectly balanced and not directly in the center. Since the platter wobbled a bit no matter the speed, if the bowl was not in the center, it would just throw off the flame even …show more content…
One of the reasons that the flames decreased in height when speed was increased was that platter became more wobbly when spinning. This wobbling made it hard for the flame to build up, and made the flame more sporadic since the amount of air being supplied to it was varying. The air vents did help
Since the flame was constantly changing height, it was impossible to set the camera to the same height as the flame to view, so that limited how accurate the measurements were. The flame is also constantly moving so 26 data points might not have been enough to get a good average of the data.
In order for the flame to reach more than 10 inches, the flame needed
If I were to get a smoother rotation with equal sized vents, I could get larger flames.
