deflagration

Deflagration is a type of rapid combustion where a flame moves through a flammable material at subsonic speeds, meaning slower than the speed of sound. It involves a chemical reaction releasing heat, light, and gases, causing the material to burn quickly but in a controlled manner. This process is typical in things like wood fires or gasoline explosions, where the fire spreads steadily through the material. Unlike detonations, deflagrations are less violent and produce less destructive shockwaves, making them a slower, more controlled combustion process.
