Abstract
The paper presents a fully three-dimensional coupled simulation of flame propagation through epoxy resins reinforced with glass fiber (glass–epoxy) under the action of a heat flux from two sides, using the Fire Dynamic Simulator package. The model includes three-dimensional heat and mass transfer, diffusion of basic substances in the gas phase, and diffusion transport of pyrolysis products in the solid phase. The pyrolysis and oxidation processes are represented by macroreactions and take into account the effect of the phosphorus-containing flame retardant DDM-DOPO. The model satisfactorily predicts the experimentally observed dynamics of flame propagation.
热通量作用下火焰在聚合物中传播的全三维耦合模拟
摘要 本文利用火灾动态模拟器软件包，对玻璃纤维增强环氧树脂（玻璃-环氧）在两侧热流作用下的火焰传播进行了全三维耦合模拟。该模型包括三维传热和传质、气相中基本物质的扩散以及固相中热解产物的扩散传输。热解和氧化过程由宏观反应表示，并考虑了含磷阻燃剂 DDM-DOPO 的影响。该模型能令人满意地预测实验观察到的火焰传播动态。

期刊介绍：
Technical Physics Letters is a companion journal to Technical Physics and offers rapid publication of developments in theoretical and experimental physics with potential technological applications. Recent emphasis has included many papers on gas lasers and on lasing in semiconductors, as well as many reports on high Tc superconductivity. The excellent coverage of plasma physics seen in the parent journal, Technical Physics, is also present here with quick communication of developments in theoretical and experimental work in all fields with probable technical applications. Topics covered are basic and applied physics; plasma physics; solid state physics; physical electronics; accelerators; microwave electron devices; holography.
