Smoke propagation into a corridor configuration is an important issue in fire safety engineering. One important characteristic is the smoke behaviour in the steady state, namely, the smoke layer thickness, its mean temperature and its mean velocity. The question that is investigated here is how these quantities vary as a function of the corridor geometrical characteristics and of the fire heat release rate. To achieve this goal, new experimental data are provided in a small scale configuration. The results show that the smoke layer thickness is independent of the heat release rate of the pool fire. By rescaling the velocity and temperature profiles with respect to the fire heat release rate, these profiles fall onto unique curves. Finally, based on energy and mass conservation equations, a scaling relation is proposed for the smoke enthalpy.

小长度走廊中烟流的实验表征

烟雾进入走廊配置是消防安全工程中的一个重要问题。一个重要的特征是稳态下的烟气行为，即烟层厚度、平均温度和平均速度。这里研究的问题是这些量如何作为走廊几何特征和火灾热释放率的函数而变化。为了实现这一目标，在小规模配置中提供了新的实验数据。结果表明，烟层厚度与池火的放热率无关。通过相对于火灾热释放率重新调整速度和温度曲线，这些曲线落在独特的曲线上。最后，基于能量守恒方程和质量守恒方程，提出了烟焓的标度关系。
