The modeling of fire whirlwinds
Webhour, these winds had not been hitting the fire area. Suddenly an intense whirlwind formed in adjacent green timber and passed over the dormant slash fire. The fire leaped to life with an erup tion of sparks and flame and ran for over a mile finally joining a second fire. (See example No. 9, Table 1.) Fire whirlwinds have received little attention Webfire whirlwinds. Byram and Martin 6 reported on fire whirlwind modeling in the laboratory using solid walls to generate the eddy. They later used both air jets and fire to form the generating eddy and reported updraft velocities in laboratory chambers of 43 ft/sec (13 m/sec)2, s Burning
