Fire whirls have long fascinated the research community, however their destructive power has hidden many features of their formation, growth and propagation. Most of what is known about fire whirls, therefore, comes from scale modeling experiments in the laboratory. Both the methods of formation, dominated by wind and geometry, and the inner structure of the whirl, including velocity and temperature fields, have been studied at this scale. The particular case of quasi-steady fire whirls directly over a fuel source forms the bulk of current experimental knowledge, despite many other cases existing in nature. The present article reviews the state of knowledge concerning the fluid dynamics of fire whirls, including the conditions for their formation, their structure and the mechanisms which control their unique state. Finally, recent discoveries will be highlighted as well as potential research avenues for the future.

火旋风

火旋风长期以来一直让研究界着迷，但其破坏力隐藏了其形成、生长和传播的许多特征。因此，大部分关于火旋风的知识都来自实验室中的比例模型实验。以风和几何学为主的形成方法和漩涡的内部结构，包括速度和温度场，都在这个尺度上进行了研究。尽管自然界中存在许多其他情况，但准稳态火直接在燃料源上旋转的特殊情况构成了当前实验知识的大部分。本文回顾了关于火旋风流体动力学的知识状态，包括其形成条件、结构和控制其独特状态的机制。最后，
