#PhyFron கீவெளியில் "ஆகாயம் தீப்பிடிச்சா" என்ற தலைப்பில் "Microgravity Combustion" பற்றி உரையாற்றிய அவர்களுக்கு நன்றி. இன்று @engaareaa உரையில் சொன்ன தகவல் தொடர்பான சில குறிப்பிடல்கள் கீழே

1.Combustion is another word for burning. In a combustion reaction, a fuel is heated and it reacts with oxygen.

2.The first microgravity combustion experiment was performed in 1997 aboard the Columbia shuttle. Called Structure of Flame Balls at Low Lewis-number

3.
How Wildfires Work
After combustion occurs and a fire begins to burn, there are several factors that determine how the fire spreads. These three factors include fuel, weather and topography.

4. Microgravity is the condition in which people or objects appear to be weightless. The effects of microgravity can be seen when astronauts and objects float in space

4.Buoyancy Effect on Downward Flame
doi.org/10.1007/s10694…
Understanding material flammability is important for fire safety applications in space facilities where the environments may include microgravity, low velocity flows, low pressure and elevated oxygen concentration

5.Fire Prevention in Space
If a fire were to break out on a spacecraft in orbit, astronauts would fight the flames in slightly different ways than they would on Earth.

6.Surface to Volume ratio
The ratio between the surface area of an object, such as a fuel particle, to its volume. The smaller the particle, the more quickly it can become wet, dry out, or become heated to combustion temperature during a fire.

7.Fire in Microgravity
In space, flames don’t extinguish under the same low-oxygen conditions that would put them out on Earth, setting the stage for dangerous flare-ups.

8.Swissair flight 111 aviation disaster

Swissair flight 111, flight of a passenger airliner that crashed on September 2, 1998, off the coast of Nova Scotia, Canada, killing all 229 on board.

9. Zero-G Experiments on Earth: The Bremen Drop Tower
In Bremen, Germany, there's a tower more than a hundred metres high: it's called the Fallturm, or the Drop Tower. If you want a cost-effective way to test an experiment in microgravity -

10. a . parabolic flights
Parabolic flights are aircraft flights conducted with specific mission profiles using specially converted aeroplanes.
