对某仓库货架火灾进行了全尺寸实验和数值模拟，研究了货架火灾的着火方式、火蔓延和燃烧特性。采用计算流体动力学（CFD）模型FDS（Fire Dynamics Simulator）数值求解火灾的Navier-Stokes方程。首先进行了烟头和打火机点火方式实验。在此基础上，进行了一个全尺寸的货架火灾实验。测量了火灾过程中的温度，分析了火灾的发展和蔓延过程。采用数值模型对实验进行模拟，研究了温度、火生长和热释放速率。在数值模拟中，分析了网格尺寸分辨率。将实验测得的温度和火的生长与蔓延过程与数值模拟结果进行了比较。计算结果与实验结果吻合较好。在实验和模拟中也观察到了烟囱效应。这些有用的数据可以帮助整个仓库火灾事故的数值重建。
Full-scale experiment and numerical simulations are carried out on a shelf fire in a storehouse to study the ignition manner, the fire spread and the combustion characteristics. A computational fluid dynamics (CFD) model of fire-driven fluid flow, FDS (Fire Dynamics Simulator), is used to solve numerically a form of the Navier–Stokes equations for fire. Ignition manner experiments with both cigarette ends and lighter are conducted first. Then a full-scale experiment on a shelf fire is performed. The temperatures are measured and the fire growth and spread process is analyzed. A numerical model is used to simulate the experiment; the temperatures, fire growth and heat release rate are studied. In numerical simulations, the grid size resolution is analyzed. The experimental results of temperatures and the fire growth and spread process are compared with the results of numerical simulations. It shows that the numerical results are in good agreement with the experimental results. The chimney effect is also observed in both the experiment and the simulation. These useful data can be helpful in the numerical reconstruction of the whole storehouse fire accident.
