The experiment with a model of the fire whirl arranged small-scale fire sources which used alcohol, and conducted it. The interval was prepared between the flames of fire sources, the air current flowed in between them, and the whirl occurred by being mixed with the ascending current by a flame. The point currently solved were the following that (1) if a side wind is strong, a whirl will not occur, (2) if two or more collected heat sources exist and each heat source has an interval, it will be easy to generate a fire whirl. Analysis was conducted about the heat sources pattern arranged into L character, and has checked generating of the same whirl as an experiment.

用火焰旋风模型进行的实验是在使用酒精的小型火源上设置火焰，在火源的火焰之间设置间隙，使气流在其间流动，通过火焰与上升气流混合而产生旋风。目前解决的问题如下：（1）如果侧风强，则不会发生旋风，（2）如果存在两个或更多个收集的热源并且每个热源具有间隔，则容易产生火旋风。分析了L形热源布置方式，并通过实验验证了相同涡动的产生。
