CircleOfFire by Totte

Just a little hint what can be done with this

Yes, this is very nice constructed and very well choosen colors and it seems realistic as a circle.

If you want to make a ARTISTIC or SURREALISTIC ring of fire, this is nice and gives a good effect, but if you want to make a REALISTIC ring of fire, all the flames must go always upward.

If a black hole would be in the middle of Totte´s circle of fire, would this be a real representation? as all the flames would be attracted to the center by the black hole force and gravity

Kraellin as you have given a clue to realistic fire I want to expand this.

Very short answer, heat always go up!

Short simply answer 1

When something burns, the chemical reactions that are occurring release heat. The heat warms the air in and around the fire. Warm air rises. That is why it is sometimes hotter up near the ceiling than down by the floor. When the warmed air in and around the fire rises upward, more air flows toward the fire to replace the part that went up. The inflowing air comes fr om all directions -- from around the sides and from under the burning material. This airflow tends to confine the flames. As a result, the flames have nowhere to go but up.

Short answer 2

When a fire burns, the hot air is less dense and thus rises. this creates a vacuum effect that pulls cooler air in from the sides, continuing to fuel the fire. The flame is just following the air currents generated by its own heat.

In space, a flame doesn't do this because air density doesn't force air to rise. In space a candle looks more like a sparkler because there is no direction wh ere 'rising' has any relevance without gravity. The candle just pushes the flame away from its source fuel in all directions as the air expands.

Longer more explained answer

How a flame burns is determined by the Earth’s gravitational force. Fire is a chemical reaction of oxygen with fuel like wood or petrol etc. Presence of Oxygen and heating of fuel to the ignition temperature is required for combustion to happen. When Combustion occurs, oxygen in the air is consumed accompanied by production of other gases like carbon dioxide with transformation of energy into heat and light.

Transformed energy heats up the gases produced, increasing the gases temperature than the environment. Hot gases expand and possess lower density than the atmosphere surrounding it and hence the gases move upwards. Fire burns upwards as the heated gases carry energy and move upwards.

Normal flame assumes the shape of a tear drop as a result of upward convection of air and buoyancy supported by gravity.

In the case of no gravity no convection current is present and buoyancy would be zero forcing the flame to assume the shape of a sphere. Flame would not burn longer as there is no upward movement and oxygen in the surrounding would be consumed quickly.

Ever seen a circular gas burner where the flames always goes outwards?

Lots of images showing gas burners

Yes, is true that in a circular gas burner flames always go outwards and also upwards as soon as they can

Why they go outward ? Because the holes where the flames go through are on the sides and covered by the metal disc so it can´t go up, must go to the side but then as soon as the flame can, it makes a curve and goes upward.

ALL the circular gas burner go the flame outwards ? No, if the holes are on the top and not in the sides, flames will not go outwards and will go only upward, as seen in some of the images shown in the Google link.

This looks better?

Please answer me to this question, do you want to make an ARTISTIC or SURREALISTIC ring of fire? Or do you want a true real ring of fire as in nature ?

Yes is better, if it is artistic this is very nice and beautiful, and well constructed and very well choosen colors and it seems realistic "as a full circle", and a very dangerous fire ring.

Also must have a very powerful fuel or gas source to make such a huge dangerously ferocious flames

If you want to make it true realistic, I am sorry but is not better as the flames keep going downward, and this can´t happen

Here are some examples if you want a true real ring of fire

Realistic Ring with few flames

Car going through a real ring of fire

Lion going through real ring of fire
