How flame propagate?

Flame propagation refers to the spread of flames through a combustible material or gas mixture. It occurs when a heat source ignites the fuel, producing hot gases that rise and create convection currents, which in turn can ignite nearby fuel. The flame spreads as the heat from the combustion process heats adjacent fuel, leading to further ignition. Factors influencing flame propagation include the type of fuel, concentration, temperature, and environmental conditions such as wind and pressure.
