Abstract:
Fire whirls are a rare but potentially catastrophic form
of fire. In order for one to exist, there must be an
external source of organized angular momentum that
products large swirl velocity components as air is
entrained into the fire plume. The vertical
acceleration induced by the buoyancy generates strain
fields which stretch out the flames as they wrap around
the nominal plume centerline. Fire whirls are known to
increase substantially the danger of naturally occurring
or post-disaster fires.
