Study on the Dynamic Characteristics of Fire Whirl

In the forest fire, fire whirl wind often appears. In the atmospheric surroundings, the gas density of flame is nonuniformity because of the nonuniformity of its temperature, and this nonuniformity can produce a difference between the flame and its surroundings. Moreover, because of the Coroilis force, a fire whirl will be produced; Furthermore, the Coroilis force also has an effect on the rotating direction of fire whirl.
