摘要 就热分解效果而言的一个改进的数字热转移模型被建议预言受到辐射热 flux.The 模型的耐热织物的热性能在织物 thermophysical properties.The 合并导致热的变化新模型与试验性的数据表演从抗火的棉花 fabrics.Comparison 的修改绚烂的保护的表演( RPP )测试与数据被验证了在 charrin 以内的集体损失率和温度侧面的预言 An improved numerical heat transfer model considering pyrolysis effect is proposed to predict thermal performance of heat-resistant fabric subjected to radiant heat flux. The model incorporates the heat-induced changes in fabric thermophysical properties. The new model has been validated with data from modified Radiant Protective Performance (RPP) tests of flame-resistant cotton fabrics. Comparison with experimental data shows that the predictions of mass loss rates and temperature profiles within the charring material and skin simulant are in reasonably good agreement with the experiments. Results from the numerical model contribute to a better understanding of the heat transfer process within flame-resistant fabrics under high heat flux conditions, and also to establish a systematic method for analyzing heat transfer in other fibrous materials applications.
