| 摘 要： | 在森林火灾中，各种旋涡大量存在，着火物在旋转流场作用下运动导致火灾蔓延．本文采用二相流单颗粒模型，研究了着火物在火焰旋涡流场中的运动，给出了环境气流分别以Ｂｕｒｇｅｒｓ涡和Ｓｕｌｉｖａｎ涡作旋转运动时，着火物的运动规律．结果表明，着火物将在火焰旋涡流场作用下，被加速带到高空，并飞离流场，形成飞火传播．

| Abstract: | There are various vortices in forest fires. Under rotating flow field action, burning debris result in fire spread . In this paper, the model of single particle for two phase flow is used, the motion law of the burning debris in fire whirl flow is studied ,and the laws of fire whirl and fire propagation are revealed. |
