火灾模型是从工程科学的角度出发，分析研究火灾的发生、发展，烟气蔓延以及火灾对周围环境诸如建筑设备、森林植被及大气环境等影响的数学模型。介绍了广泛应用于建筑物内部受限空间的场、区域、网模型以及经验模型的理论思想与数学方程，分析了4种模型在相应环境下应用的合理性，并对火灾模型的发展做出了展望。

The aim of the present review is to provide the reader with a brief discussion on the mathematical modeling techniques, currently available for compartment fires. The relevant underlying physical assumptions are presented first and the conventional model performance is analyzed in the range of application. The final part of the review deals with current trends and perspective of mathematic fire models and highlights the need for extensive validation studies and interaction between theoretical and experimental investigations.
