在发生火灾如城市火灾的情况下，有时会产生旋流，即所谓的火旋风。火旋风的产生是一种罕见但潜在的灾难性火灾形式。为了控制火旋风的产生，必须明确火旋风的产生机理。本文对旋转火焰进行了实验和数值模拟研究。实验装置采用丙烷燃烧器作为火源。在实验中测量了火旋风的温度和速度分布。此外，利用CFD软件对火焰旋转现象进行了预测。计算流体力学程序，这是FDS Ver.3.1在NIST开发的，用于数值模拟。
In case that conflagration such as urban fire occurred, there is case which the swirl flow, so-called fire whirls sometimes generates. The generation of fire whirls is a rare but potentially catastrophic form of fires. In order to control of fire whirls, it is important to specify the generating mechanism. In this paper, experimental and numerical studies are reported on whirling flames, which modeled fire whirls. A propane burner was used as a fire source of experiment apparatus. The distribution of temperature and velocity of fire whirl were measured in experiments. Moreover, the prediction of fire whirls phenomenon was carried out by using CFD code. The CFD code, which is the FDS Ver.3.1 developed in NIST, was used for numerical simulation.
