In summary, shaping fire is possible, but it is dependent on the presence of gravity and convective flow. Without these factors, the flame will take on a spherical shape. Additionally, controlling the flow of fuel and oxidizer is necessary to maintain a shaped flame.

Hi,
I'd like to ask, if its possible to shape a fire. Would it be possible on tealight ?
I don't want complex shapes just simple ones like sphere, cylinder...

Thanks

martin1512: What is a tealight? If you want to "shape" fire I suggest you study this first, then you may decide for yourself what is possible:

The shape of a tealight (or any small candle/match/lighter flame) is driven by buoyancy and convective flow. Take away gravity, and flames become spherical. Of course, once you take away convective flow, you have to control the flow of fuel and oxidizer otherwise the flame will burn out:

FAQ: Shape Tealight Flame - Simple Sphere & Cylinder

What is the shape of a tealight flame?

The shape of a tealight flame is typically a simple sphere or cylinder. It can vary slightly depending on the specific conditions and environment, but the overall shape remains consistent.

Why is the shape of a tealight flame important?

The shape of a tealight flame is important because it can indicate the efficiency and quality of the burning process. A well-shaped flame is a sign of a clean and complete combustion, while an irregular or flickering flame can indicate an issue with the fuel or oxygen supply.

What factors can affect the shape of a tealight flame?

The shape of a tealight flame can be influenced by several factors, including the type and quality of the fuel (e.g. wax or oil), the size and design of the wick, the amount of oxygen present, and the surrounding temperature and air flow.

Can the shape of a tealight flame be manipulated?

Yes, the shape of a tealight flame can be manipulated by adjusting the surrounding conditions. For example, blowing on the flame can cause it to flicker or change shape, while increasing the oxygen supply can result in a taller and more stable flame.

How does the shape of a tealight flame compare to other types of flames?

The shape of a tealight flame is similar to other types of flames, such as a candle flame or a gas stove flame. However, the size and intensity may vary depending on the specific fuel and conditions. Overall, all flames have a similar shape due to the natural tendency of hot air to rise and cool air to sink, creating a convection current.
